  Use the DMA_{64,32}BIT_MASK constants from dma-mapping.h when calling
  pci_set_dma_mask() or pci_set_consistent_dma_mask()

Subject:   [PATCH] drivers/net/smc-mca.c: cleanups

  This patch contains the following cleanups:
  - make a needlessly global function static
  - make three needlessly global structs static const

  Since after moving the now-static stucts to smc-mca.c the file smc-mca.h
  was empty except for two #define's, I've also killed the rest of
  smc-mca.h .

Subject: [PATCH] smc91c92_cs: Reduce stack usage in smc91c92_event()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch reduces the stack usage of the function smc91c92_event() in
smc91c92_cs driver from 3540 to 132.  Currently this is the highest stack
user in linux-2.6.12-rc2-mm3.  I used a patched version of gcc 3.4.3 on
i386 with -fno-unit-at-a-time disabled.

The patch has only been compile tested.

Subject: Input: This patch implements compat_ioctl for joydev.

       I've tested it with a Logitech WingMan Rumblepad on an x86-64
       machine, and on an ia32 machine to make sure I didn't break
       anything.

+ *   Complete rewrite to support Linux 2.6.10, thanks to mtouchusb.c for hints.
+ *   Unfortunately no calibration support at this time.
+ * 
+ * 1.2.1  09/03/2005 (HCE) hc@mivu.no
+ *   Code cleanup and adjusting syntax to start matching kernel standards

Subject: Input: add semaphore and user count to input_dev structure;       
 serialize open and close calls and ensure that device's        open and close
 methods are only called when first user        opens it or last user closes
 it.

Subject: Input: HID items of width 32 (bits) or greater are incorrectly
 extracted        due to a masking bug in hid-core.c:extract(). This patch
 fixes it        up by forcing the mask to be 64 bits wide.

Subject: Input: lifebook - various cleanups:        - do not try to set rate
 and resolution in init method, let          psmouse core do it for us. This
 also removes special quirks          from the core;        - do not disable
 mouse before doing full reset - meaningless;        - some formatting and
 whitespace cleanups.

Subject: Input: ALPS - fix forward/back buttons on Ahtec laptop.

I have an Ahtec laptop with a ALPS GlidePoint device, with 4 buttons.
With Linux hernel 2.6.12rc4 and rc5 I'm unable to use the vertical
scroll buttons (BACK and FORWARD).

BACK gets detected as BTN_MIDDLE and FORWARD is undetected.

I've modified the drivers/input/mouse/alps.c from 2.6.12rc5 and now it
works fine!

Subject: Input: return correct value when setting up absolute device via
 uinipt.

uinput_alloc_device() is supposed to return the number of bytes read,
the value is returned to uinput_write() and from there to userspace. If
EV_ABS is set then it returns the value from uinput_validate_absbits()
instead, which is zero when everything is ok instead of the count.

Subject: Input: do not corrupt system-wide procfs fops.

entry->proc_fops is a pointer to struct file_operations. When we
call create_proc_entry(...), it pointis to proc_file_operations,
deep in fs/proc/generic.c. By adding a 'poll' member to this struct
we effectively force the 'poll' member on every file in /proc,
which is wrong (they all fail select(...) calls).

This patch changes a copy of entry->proc_fops and reassigns it rather
than changing the original member.

From 04df1925fcda9a35c716423ad2b73abd70eb0913 Mon Sep 17 00:00:00 2001
From: Dmitry Torokhov <dtor_core@ameritech.net>
Date: Wed, 1 Jun 2005 02:39:44 -0500
Subject: Input: pmouse - introduce proper locking so state-changing       
 operations do not iterfere with each other.        Also make sure that serio
 core takes serio->drv_sem        not only for connect/disconnect but for
 reconnect        too.

From c611763d048990de5cdf848d97af6392f8fa7430 Mon Sep 17 00:00:00 2001
From: Dmitry Torokhov <dtor_core@ameritech.net>
Date: Wed, 1 Jun 2005 02:39:51 -0500
Subject: Input: add ps2_drain() to libps2 to allow reading and discarding     
   given number of bytes from device. Change ps2_command to        allow using
 0 as command ID and actually pass it to the        device instead of working
 as a drain.

Subject: drm: 32/64-bit DRM ioctl compatibility patch

The patch is against a 2.6.11 kernel tree.  I am running this with a
32-bit X server (compiled up from X.org CVS as of a couple of weeks
ago) and 32-bit DRI libraries and clients.  All the userland stuff is
identical to what I am using under a 32-bit kernel on my G4 powerbook
(which is a 32-bit machine of course).  I haven't tried compiling up a
64-bit X server or clients yet.

In the compatibility routines I have assumed that the kernel can
safely access user addresses after set_fs(KERNEL_DS).  That is, where
an ioctl argument structure contains pointers to other structures, and
those other structures are already compatible between the 32-bit and
64-bit ABIs (i.e. they only contain things like chars, shorts or
ints), I just check the address with access_ok() and then pass it
through to the 64-bit ioctl code.  I believe this approach may not
work on sparc64, but it does work on ppc64 and x86_64 at least.

One tricky area which may need to be revisited is the question of how
to handle the handles which we pass back to userspace to identify
mappings.  These handles are generated in the ADDMAP ioctl and then
passed in as the offset value to mmap.  However, offset values for
mmap seem to be generated in other ways as well, particularly for AGP
mappings.

The approach I have ended up with is to generate a fake 32-bit handle
only for _DRM_SHM mappings.  The handles for other mappings (AGP, REG,
FB) are physical addresses which are already limited to 32 bits, and
generating fake handles for them created all sorts of problems in the
mmap/nopage code.

This patch has been updated to use the new compatibility ioctls.

From 169a3e66637c667b43dab7c319ffd5c99804cad8 Mon Sep 17 00:00:00 2001
From: Jay Vosburgh <fubar@us.ibm.com>
Date: Sun, 26 Jun 2005 17:54:11 -0400
Subject: bonding: xor/802.3ad improved slave hash

Add support for alternate slave selection algorithms to bonding
balance-xor and 802.3ad modes.  Default mode (what we have now: xor of
MAC addresses) is "layer2", new choice is "layer3+4", using IP and port
information for hashing to select peer.

Originally submitted by Jason Gabler for balance-xor mode;
modified by Jay Vosburgh to additionally support 802.3ad mode.  Jason's
original comment is as follows:

The attached patch to the Linux Etherchannel Bonding driver modifies the
driver's "balance-xor" mode as follows:

      - alternate hashing policy support for mode 2
        * Added kernel parameter "xmit_policy" to allow the specification
          of different hashing policies for mode 2.  The original mode 2
          policy is the default, now found in xmit_hash_policy_layer2().
        * Added xmit_hash_policy_layer34()

This patch was inspired by hashing policies implemented by Cisco,
Foundry and IBM, which are explained in
Foundry documentation found at:
http://www.foundrynet.com/services/documentation/sribcg/Trunking.html#112750

Subject: 8139cp: safer spin loop for get_statistics

The spin loop in 8139cp is limited to 100 iterations when pulling hardware
stats. There is no allowance for processor speed so on a fast machine, the
stats may not be available that fast. Also, if the board doesn't return
soon enough make sure turn the address back off to prevent later updates
when memory has gone away.

From 1e7f0bd8c8f2d0496ad338be5e69ff4395d77da4 Mon Sep 17 00:00:00 2001
From: Domen Puncer <domen@coderock.org>
Date: Sun, 26 Jun 2005 18:22:14 -0400
Subject: drivers/net/: Use the DMA_{64,32}BIT_MASK constants

Use the DMA_{64,32}BIT_MASK constants from dma-mapping.h when calling
pci_set_dma_mask() or pci_set_consistent_dma_mask()

This patch includes dma-mapping.h explicitly because it caused errors
on some architectures otherwise.

See http://marc.theaimsgroup.com/?t=108001993000001&r=1&w=2 for details

Subject: [PATCH] pcnet_cs.c: IRQ handler optimization

During some performance diagnostics I stumbled on this slightly wasteful
code in pcnet_cs.c which I made the patch included at the bottom for (two
minor comment fixes included).

Improvement:
instead of *always* calculating
lea    0x2c0(%edx),%ebx
and then additionally doing the
mov    %edx,0xc0(%ebx)
addition *if we need it*,

we now do the *whole* calculation of
mov    %edx,0x380(%ebx)
*only* if we need it.
This even manages to save us a whole 16-byte alignment buffer loss
in this compilation case.

Result: slightly improves IRQ handler performance in both shared and
non-shared IRQ case, which should make my rusty P3/700 a slight bit happier.

Thank you for your support,

Andreas Mohr

Subject: [PATCH] document that 8139TOO supports 8129/8130

The 8129/8130 support is a sub-option that is not visible if the user
hasn't enabled the 8139 support.

Let's make it a bit easier for users to find the driver for their nic.

Subject: [PATCH] defxx: Use irqreturn_t for the interrupt handler

This is a fix for the interrupt handler in the defxx driver to use
irqreturn_t.  Beside the obvious fix of returning a proper status at all,
it actually checks board registers as appropriate for determining if an
interrupt has been recorded in the bus-specific interface logic.

The patch also includes an obvious one-line fix for SET_NETDEV_DEV needed
for the EISA variation, for which I've decided there is no point in sending
separately.

Subject: [PATCH] net/sb1000: replace nicedelay() with ssleep()

Use ssleep() instead of nicedelay()
to guarantee the task delays as expected. Remove the prototype and
definition of nicedelay(). This is a very weird function, because it is
called to sleep in terms of usecs, but always sleeps for 1 second,
completely ignoring the parameter. I have gone ahead and followed suit,
just sleeping for a second in all cases, but maybe someone with the
hardware could tell me if perhaps the paramter *should* matter. Additionally,
nicedelay() is called in TASK_INTERRUPTIBLE state, but doesn't deal with signals
in case these longer delays do not complete, so I believe ssleep() is more
appropriate.

Subject: [PATCH] drivers/net/skfp/: cleanups

This patch contains the following cleanups:
- make needlessly global code static
- remove the completely unused smtparse.c
- remove the following unused global functions:
  - drvfbi.c: init_dma
  - drvfbi.c: dis_dma
  - drvfbi.c: get_rom_byte
  - drvfbi.c: mac_drv_vpd_read
  - drvfbi.c: mac_drv_pci_fix
  - fplustm.c: mac_set_func_addr
  - fplustm.c: mac_del_multicast
  - hwmtm.c: mac_drv_rx_frag
  - pcmplc.c: pcm_set_lct_short
  - smt.c: smt_please_reconnect
  - smt.c: smt_change_t_neg
  - smtdef.c: smt_set_defaults

Subject: [PATCH] orinoco: always use 802.11 header for rx processing

If the frame has ToDS flag set, mark it by setting skb->pkt_type to
PACKET_OTHERHOST, so that applications unaware of promiscous mode won't get
uplink (STA->AP) packets for STA->STA transmissions relayed by the AP.
Thanks to John Denker and David Gibson for finding the problem and the
solution.

Patch from Pavel Roskin

 /*
- * v0.01 -> v0.02 - 21/3/2001 - Jean II
- *	o Allow to use regular ethX device name instead of dldwdX
- *	o Warning on IBSS with ESSID=any for firmware 6.06
- *	o Put proper range.throughput values (optimistic)
- *	o IWSPY support (IOCTL and stat gather in Rx path)
- *	o Allow setting frequency in Ad-Hoc mode
- *	o Disable WEP setting if !has_wep to work on old firmware
- *	o Fix txpower range

- *	o Fix Prism2/Symbol WEP to accept 128 bits keys
- *	o Add Symbol WEP (add authentication type)
- *	o Add Prism2/Symbol rate
- *	o Add PM timeout (holdover duration)
- *	o Enable "iwconfig eth0 key off" and friends (toggle flags)
- *	o Enable "iwconfig eth0 power unicast/all" (toggle flags)
- *	o Try with an Intel card. It report firmware 1.01, behave like
- *	  an antiquated firmware, however on windows it says 2.00. Yuck !
- *	o Workaround firmware bug in allocate buffer (Intel 1.01)
- *	o Finish external renaming to orinoco...
- *	o Testing with various Wavelan firmwares
- *
- * v0.03 -> v0.04 - 30/3/2001 - Jean II
- *	o Update to Wireless 11 -> add retry limit/lifetime support
- *	o Tested with a D-Link DWL 650 card, fill in firmware support
- *	o Warning on Vcc mismatch (D-Link 3.3v card in Lucent 5v only slot)
- *	o Fixed the Prism2 WEP bugs that I introduced in v0.03 :-(
- *	  It works on D-Link *only* after a tcpdump. Weird...
- *	  And still doesn't work on Intel card. Grrrr...
- *	o Update the mode after a setport3
- *	o Add preamble setting for Symbol cards (not yet enabled)
- *	o Don't complain as much about Symbol cards...
- *
- * v0.04 -> v0.04b - 22/4/2001 - David Gibson
- *      o Removed the 'eth' parameter - always use ethXX as the
- *        interface name instead of dldwdXX.  The other was racy
- *        anyway.
- *	o Clean up RID definitions in hermes.h, other cleanups
- *
- * v0.04b -> v0.04c - 24/4/2001 - Jean II
- *	o Tim Hurley <timster AT seiki.bliztech.com> reported a D-Link card
- *	  with vendor 02 and firmware 0.08. Added in the capabilities...
- *	o Tested Lucent firmware 7.28, everything works...
- *
- * v0.04c -> v0.05 - 3/5/2001 - Benjamin Herrenschmidt
- *	o Spin-off Pcmcia code. This file is renamed orinoco.c,
- *	  and orinoco_cs.c now contains only the Pcmcia specific stuff
- *	o Add Airport driver support on top of orinoco.c (see airport.c)
- *
- * v0.05 -> v0.05a - 4/5/2001 - Jean II
- *	o Revert to old Pcmcia code to fix breakage of Ben's changes...
- *
- * v0.05a -> v0.05b - 4/5/2001 - Jean II
- *	o add module parameter 'ignore_cis_vcc' for D-Link @ 5V
- *	o D-Link firmware doesn't support multicast. We just print a few
- *	  error messages, but otherwise everything works...
- *	o For David : set/getport3 works fine, just upgrade iwpriv...
- *
- * v0.05b -> v0.05c - 5/5/2001 - Benjamin Herrenschmidt
- *	o Adapt airport.c to latest changes in orinoco.c
- *	o Remove deferred power enabling code
- *
- * v0.05c -> v0.05d - 5/5/2001 - Jean II
- *	o Workaround to SNAP decapsulate frame from Linksys AP
- *	  original patch from : Dong Liu <dliu AT research.bell-labs.com>
- *	  (note : the memcmp bug was mine - fixed)
- *	o Remove set_retry stuff, no firmware support it (bloat--).
- *
- * v0.05d -> v0.06 - 25/5/2001 - Jean II
- *		Original patch from "Hong Lin" <alin AT redhat.com>,
- *		"Ian Kinner" <ikinner AT redhat.com>
- *		and "David Smith" <dsmith AT redhat.com>
- *	o Init of priv->tx_rate_ctrl in firmware specific section.
- *	o Prism2/Symbol rate, upto should be 0xF and not 0x15. Doh !
- *	o Spectrum card always need cor_reset (for every reset)
- *	o Fix cor_reset to not lose bit 7 in the register
- *	o flush_stale_links to remove zombie Pcmcia instances
- *	o Ack previous hermes event before reset
- *		Me (with my little hands)
- *	o Allow orinoco.c to call cor_reset via priv->card_reset_handler
- *	o Add priv->need_card_reset to toggle this feature
- *	o Fix various buglets when setting WEP in Symbol firmware
- *	  Now, encryption is fully functional on Symbol cards. Youpi !
- *
- * v0.06 -> v0.06b - 25/5/2001 - Jean II
- *	o IBSS on Symbol use port_mode = 4. Please don't ask...
- *
- * v0.06b -> v0.06c - 29/5/2001 - Jean II
- *	o Show first spy address in /proc/net/wireless for IBSS mode as well
- *
- * v0.06c -> v0.06d - 6/7/2001 - David Gibson
- *      o Change a bunch of KERN_INFO messages to KERN_DEBUG, as per Linus'
- *        wishes to reduce the number of unnecessary messages.
- *	o Removed bogus message on CRC error.
- *	o Merged fixes for v0.08 Prism 2 firmware from William Waghorn
- *	  <willwaghorn AT yahoo.co.uk>
- *	o Slight cleanup/re-arrangement of firmware detection code.
- *
- * v0.06d -> v0.06e - 1/8/2001 - David Gibson
- *	o Removed some redundant global initializers (orinoco_cs.c).
- *	o Added some module metadata
- *
- * v0.06e -> v0.06f - 14/8/2001 - David Gibson
- *	o Wording fix to license
- *	o Added a 'use_alternate_encaps' module parameter for APs which need an
- *	  oui of 00:00:00.  We really need a better way of handling this, but
- *	  the module flag is better than nothing for now.
- *
- * v0.06f -> v0.07 - 20/8/2001 - David Gibson
- *	o Removed BAP error retries from hermes_bap_seek().  For Tx we now
- *	  let the upper layers handle the retry, we retry explicitly in the
- *	  Rx path, but don't make as much noise about it.
- *	o Firmware detection cleanups.
- *
- * v0.07 -> v0.07a - 1/10/3001 - Jean II
- *	o Add code to read Symbol firmware revision, inspired by latest code
- *	  in Spectrum24 by Lee John Keyser-Allen - Thanks Lee !
- *	o Thanks to Jared Valentine <hidden AT xmission.com> for "providing" me
- *	  a 3Com card with a recent firmware, fill out Symbol firmware
- *	  capabilities of latest rev (2.20), as well as older Symbol cards.
- *	o Disable Power Management in newer Symbol firmware, the API 
- *	  has changed (documentation needed).
- *
- * v0.07a -> v0.08 - 3/10/2001 - David Gibson
- *	o Fixed a possible buffer overrun found by the Stanford checker (in
- *	  dldwd_ioctl_setiwencode()).  Can only be called by root anyway, so not
- *	  a big problem.
- *	o Turned has_big_wep on for Intersil cards.  That's not true for all of
- *	  them but we should at least let the capable ones try.
- *	o Wait for BUSY to clear at the beginning of hermes_bap_seek().  I
- *	  realized that my assumption that the driver's serialization
- *	  would prevent the BAP being busy on entry was possibly false, because
- *	  things other than seeks may make the BAP busy.
- *	o Use "alternate" (oui 00:00:00) encapsulation by default.
- *	  Setting use_old_encaps will mimic the old behaviour, but I think we
- *	  will be able to eliminate this.
- *	o Don't try to make __initdata const (the version string).  This can't
- *	  work because of the way the __initdata sectioning works.
- *	o Added MODULE_LICENSE tags.
- *	o Support for PLX (transparent PCMCIA->PCI bridge) cards.
- *	o Changed to using the new type-fascist min/max.
- *
- * v0.08 -> v0.08a - 9/10/2001 - David Gibson
- *	o Inserted some missing acknowledgements/info into the Changelog.
- *	o Fixed some bugs in the normalization of signal level reporting.
- *	o Fixed bad bug in WEP key handling on Intersil and Symbol firmware,
- *	  which led to an instant crash on big-endian machines.
- *
- * v0.08a -> v0.08b - 20/11/2001 - David Gibson
- *	o Lots of cleanup and bugfixes in orinoco_plx.c
- *	o Cleanup to handling of Tx rate setting.
- *	o Removed support for old encapsulation method.
- *	o Removed old "dldwd" names.
- *	o Split RID constants into a new file hermes_rid.h
- *	o Renamed RID constants to match linux-wlan-ng and prism2.o
- *	o Bugfixes in hermes.c
- *	o Poke the PLX's INTCSR register, so it actually starts
- *	  generating interrupts.  These cards might actually work now.
- *	o Update to wireless extensions v12 (Jean II)
- *	o Support for tallies and inquire command (Jean II)
- *	o Airport updates for newer PPC kernels (BenH)
- *
- * v0.08b -> v0.09 - 21/12/2001 - David Gibson
- *	o Some new PCI IDs for PLX cards.
- *	o Removed broken attempt to do ALLMULTI reception.  Just use
- *	  promiscuous mode instead
- *	o Preliminary work for list-AP (Jean II)
- *	o Airport updates from (BenH)
- *	o Eliminated racy hw_ready stuff
- *	o Fixed generation of fake events in irq handler.  This should
- *	  finally kill the EIO problems (Jean II & dgibson)
- *	o Fixed breakage of bitrate set/get on Agere firmware (Jean II)
- *
- * v0.09 -> v0.09a - 2/1/2002 - David Gibson
- *	o Fixed stupid mistake in multicast list handling, triggering
- *	  a BUG()
- *
- * v0.09a -> v0.09b - 16/1/2002 - David Gibson
- *	o Fixed even stupider mistake in new interrupt handling, which
- *	  seriously broke things on big-endian machines.
- *	o Removed a bunch of redundant includes and exports.
- *	o Removed a redundant MOD_{INC,DEC}_USE_COUNT pair in airport.c
- *	o Don't attempt to do hardware level multicast reception on
- *	  Intersil firmware, just go promisc instead.
- *	o Typo fixed in hermes_issue_cmd()
- *	o Eliminated WIRELESS_SPY #ifdefs
- *	o Status code reported on Tx exceptions
- *	o Moved netif_wake_queue() from ALLOC interrupts to TX and TXEXC
- *	  interrupts, which should fix the timeouts we're seeing.
- *
- * v0.09b -> v0.10 - 25 Feb 2002 - David Gibson
- *	o Removed nested structures used for header parsing, so the
- *	  driver should now work without hackery on ARM
- *	o Fix for WEP handling on Intersil (Hawk Newton)
- *	o Eliminated the /proc/hermes/ethXX/regs debugging file.  It
- *	  was never very useful.
- *	o Make Rx errors less noisy.
- *
- * v0.10 -> v0.11 - 5 Apr 2002 - David Gibson
- *	o Laid the groundwork in hermes.[ch] for devices which map
- *	  into PCI memory space rather than IO space.
- *	o Fixed bug in multicast handling (cleared multicast list when
- *	  leaving promiscuous mode).
- *	o Relegated Tx error messages to debug.
- *	o Cleaned up / corrected handling of allocation lengths.
- *	o Set OWNSSID in IBSS mode for WinXP interoperability (jimc).
- *	o Change to using alloc_etherdev() for structure allocations. 
- *	o Check for and drop undersized packets.
- *	o Fixed a race in stopping/waking the queue.  This should fix
- *	  the timeout problems (Pavel Roskin)
- *	o Reverted to netif_wake_queue() on the ALLOC event.
- *	o Fixes for recent Symbol firmwares which lack AP density
- *	  (Pavel Roskin).
- *
- * v0.11 -> v0.11a - 29 Apr 2002 - David Gibson
- *	o Handle different register spacing, necessary for Prism 2.5
- *	  PCI adaptors (Steve Hill).
- *	o Cleaned up initialization of card structures in orinoco_cs
- *	  and airport.  Removed card->priv field.
- *	o Make response structure optional for hermes_docmd_wait()
- *	  Pavel Roskin)
- *	o Added PCI id for Nortel emobility to orinoco_plx.c.
- *	o Cleanup to handling of Symbol's allocation bug. (Pavel Roskin)
- *	o Cleanups to firmware capability detection.
- *	o Arrange for orinoco_pci.c to override firmware detection.
- *	  We should be able to support the PCI Intersil cards now.
- *	o Cleanup handling of reset_cor and hard_reset (Pavel Roskin).
- *	o Remove erroneous use of USER_BAP in the TxExc handler (Jouni
- *	  Malinen).
- *	o Makefile changes for better integration into David Hinds
- *	  pcmcia-cs package.
- *
- * v0.11a -> v0.11b - 1 May 2002 - David Gibson
- *	o Better error reporting in orinoco_plx_init_one()
- *	o Fixed multiple bad kfree() bugs introduced by the
- *	  alloc_orinocodev() changes.
- *
- * v0.11b -> v0.12 - 19 Jun 2002 - David Gibson
- *	o Support changing the MAC address.
- *	o Correct display of Intersil firmware revision numbers.
- *	o Entirely revised locking scheme.  Should be both simpler and
- *	   better.
- *	o Merged some common code in orinoco_plx, orinoco_pci and
- *	  airport by creating orinoco_default_{open,stop,reset}()
- *	  which are used as the dev->open, dev->stop, priv->reset
- *	  callbacks if none are specified when alloc_orinocodev() is
- *	  called.
- *	o Removed orinoco_plx_interrupt() and orinoco_pci_interrupt().
- *	  They didn't do anything.
- *
- * v0.12 -> v0.12a - 4 Jul 2002 - David Gibson
- *	o Some rearrangement of code.
- *	o Numerous fixups to locking and rest handling, particularly
- *	  for PCMCIA.
- *	o This allows open and stop net_device methods to be in
- *	  orinoco.c now, rather than in the init modules.
- *	o In orinoco_cs.c link->priv now points to the struct
- *	  net_device not to the struct orinoco_private.
- *	o Added a check for undersized SNAP frames, which could cause
- *	  crashes.
- *
- * v0.12a -> v0.12b - 11 Jul 2002 - David Gibson
- *	o Fix hw->num_init testing code, so num_init is actually
- *	  incremented.
- *	o Fix very stupid bug in orinoco_cs which broke compile with
- *	  CONFIG_SMP.
- *	o Squashed a warning.
- *
- * v0.12b -> v0.12c - 26 Jul 2002 - David Gibson
- *	o Change to C9X style designated initializers.
- *	o Add support for 3Com AirConnect PCI.
- *	o No longer ignore the hard_reset argument to
- *	  alloc_orinocodev().  Oops.
- *
- * v0.12c -> v0.13beta1 - 13 Sep 2002 - David Gibson
- *	o Revert the broken 0.12* locking scheme and go to a new yet
- *	  simpler scheme.
- *	o Do firmware resets only in orinoco_init() and when waking
- *	  the card from hard sleep.
- *
- * v0.13beta1 -> v0.13 - 27 Sep 2002 - David Gibson
- *	o Re-introduced full resets (via schedule_task()) on Tx
- *	  timeout.
- *
- * v0.13 -> v0.13a - 30 Sep 2002 - David Gibson
- *	o Minor cleanups to info frame handling.  Add basic support
- *	  for linkstatus info frames.
- *	o Include required kernel headers in orinoco.h, to avoid
- *	  compile problems.
- *
- * v0.13a -> v0.13b - 10 Feb 2003 - David Gibson
- *	o Implemented hard reset for Airport cards
- *	o Experimental suspend/resume implementation for orinoco_pci
- *	o Abolished /proc debugging support, replaced with a debugging
- *	  iwpriv.  Now it's ugly and simple instead of ugly and complex.
- *	o Bugfix in hermes.c if the firmware returned a record length
- *	  of 0, we could go clobbering memory.
- *	o Bugfix in orinoco_stop() - it used to fail if hw_unavailable
- *	  was set, which was usually true on PCMCIA hot removes.
- * 	o Track LINKSTATUS messages, silently drop Tx packets before
- * 	  we are connected (avoids confusing the firmware), and only
- * 	  give LINKSTATUS printk()s if the status has changed.
- *
- * v0.13b -> v0.13c - 11 Mar 2003 - David Gibson
- *	o Cleanup: use dev instead of priv in various places.
- *	o Bug fix: Don't ReleaseConfiguration on RESET_PHYSICAL event
- *	  if we're in the middle of a (driver initiated) hard reset.
- *	o Bug fix: ETH_ZLEN is supposed to include the header
- *	  (Dionysus Blazakis & Manish Karir)
- *	o Convert to using workqueues instead of taskqueues (and
- *	  backwards compatibility macros for pre 2.5.41 kernels).
- *	o Drop redundant (I think...) MOD_{INC,DEC}_USE_COUNT in
- *	  airport.c
- *	o New orinoco_tmd.c init module from Joerg Dorchain for
- *	  TMD7160 based PCI to PCMCIA bridges (similar to
- *	  orinoco_plx.c).
- *
- * v0.13c -> v0.13d - 22 Apr 2003 - David Gibson
- *	o Make hw_unavailable a counter, rather than just a flag, this
- *	  is necessary to avoid some races (such as a card being
- *	  removed in the middle of orinoco_reset().
- *	o Restore Release/RequestConfiguration in the PCMCIA event handler
- *	  when dealing with a driver initiated hard reset.  This is
- *	  necessary to prevent hangs due to a spurious interrupt while
- *	  the reset is in progress.
- *	o Clear the 802.11 header when transmitting, even though we
- *	  don't use it.  This fixes a long standing bug on some
- *	  firmwares, which seem to get confused if that isn't done.
- *	o Be less eager to de-encapsulate SNAP frames, only do so if
- *	  the OUI is 00:00:00 or 00:00:f8, leave others alone.  The old
- *	  behaviour broke CDP (Cisco Discovery Protocol).
- *	o Use dev instead of priv for free_irq() as well as
- *	  request_irq() (oops).
- *	o Attempt to reset rather than giving up if we get too many
- *	  IRQs.
- *	o Changed semantics of __orinoco_down() so it can be called
- *	  safely with hw_unavailable set.  It also now clears the
- *	  linkstatus (since we're going to have to reassociate).
- *
- * v0.13d -> v0.13e - 12 May 2003 - David Gibson
- *	o Support for post-2.5.68 return values from irq handler.
- *	o Fixed bug where underlength packets would be double counted
- *	  in the rx_dropped statistics.
- *	o Provided a module parameter to suppress linkstatus messages.
- *
- * v0.13e -> v0.14alpha1 - 30 Sep 2003 - David Gibson
- *	o Replaced priv->connected logic with netif_carrier_on/off()
- *	  calls.
- *	o Remove has_ibss_any and never set the CREATEIBSS RID when
- *	  the ESSID is empty.  Too many firmwares break if we do.
- *	o 2.6 merges: Replace pdev->slot_name with pci_name(), remove
- *	  __devinitdata from PCI ID tables, use free_netdev().
- *	o Enabled shared-key authentication for Agere firmware (from
- *	  Robert J. Moore <Robert.J.Moore AT allanbank.com>
- *	o Move netif_wake_queue() (back) to the Tx completion from the
- *	  ALLOC event.  This seems to prevent/mitigate the rolling
- *	  error -110 problems at least on some Intersil firmwares.
- *	  Theoretically reduces performance, but I can't measure it.
- *	  Patch from Andrew Tridgell <tridge AT samba.org>
- *
- * v0.14alpha1 -> v0.14alpha2 - 20 Oct 2003 - David Gibson
- *	o Correctly turn off shared-key authentication when requested
- *	  (bugfix from Robert J. Moore).
- *	o Correct airport sleep interfaces for current 2.6 kernels.
- *	o Add code for key change without disabling/enabling the MAC
- *	  port.  This is supposed to allow 802.1x to work sanely, but
- *	  doesn't seem to yet.
- *
  * TODO
- *	o New wireless extensions API (patch from Moustafa
- *	  Youssef, updated by Jim Carter and Pavel Roskin).
  *	o Handle de-encapsulation within network layer, provide 802.11
  *	  headers (patch from Thomas 'Dent' Mirlacher)
- *	o RF monitor mode support
  *	o Fix possible races in SPY handling.
  *	o Disconnect wireless extensions from fundamental configuration.
  *	o (maybe) Software WEP support (patch from Stano Meduna).

Subject: [PATCH] smc91x: plug race between TX tasklet and driver reset

The race causes a kernel oops when smc_hardware_send_pkt() tries to
dereference pending_tx_skb which would have been freed from one of the
driver reset paths just after the tx_task tasklet has been scheduled.
This race is possible on SMP but was uncovered by the kernel RT work.

Subject: [PATCH] gianfar: Add support enhanced TSEC features on the MPC 8548

Jeff,

Just incase this got lost in the recent netdev mailing list transition
here is a nicer version of Andy's patch for gianfar.

- kumar

* TCP/IP/UDP checksumming and verification
* VLAN tag insertion/extraction
* Larger multicast hash-table
* Padding to align IP headers

Also added:
* msg lvl support
* Some whitespace cleanup

Subject: [PATCH] b44: check link state during open

Check the link state during b44_open.  This closes a 1 HZ window
that existed after b44_open ran but before the b44_timer handler ran,
during which ethtool would report "Link detected: yes" no matter what
the link state actually was.

Subject: [PATCH] Serial: Remove {un,}register_serial from 68328serial.c

68328serial.c does not make use of register_serial/unregister_serial,
which is traditionally used to register 8250-compatible UARTs with
the 8250-compatible serial driver.

Subject: [PATCH] Serial: Split 8250 port table

Add separate files for the different 8250 ISA-based serial boards.

Looking across all the various architectures, it seems reasonable that
we can key the availability of the configuration options for these
beasts to the bus-related symbols (iow, CONFIG_ISA).  We also standardise
the base baud/uart clock rate for these boards - I'm sure that isn't
architecture specific, but is solely dependent on the crystal fitted
on the board (which should be the same no matter what type of machine
its fitted into.)

From 22e2c507c301c3dbbcf91b4948b88f78842ee6c9 Mon Sep 17 00:00:00 2001
From: Jens Axboe <axboe@suse.de>
Date: Mon, 27 Jun 2005 10:55:12 +0200
Subject: [PATCH] Update cfq io scheduler to time sliced design

This updates the CFQ io scheduler to the new time sliced design (cfq
v3).  It provides full process fairness, while giving excellent
aggregate system throughput even for many competing processes.  It
supports io priorities, either inherited from the cpu nice value or set
directly with the ioprio_get/set syscalls.  The latter closely mimic
set/getpriority.

This import is based on my latest from -mm.

Subject: [PATCH] Fix cfq_find_next_crq()

In cfq_find_next_crq(), cfq tries to find the next request by choosing
one of two requests before and after the current one.  Currently, when
choosing the next request, if there's no next request, the next
candidate is NULL, resulting in selection of the previous request.  This
results in weird scheduling.  Once we reach the end, we always seek
backward.

The correct behavior is using the first request as the next candidate.
cfq_choose_req() already has logics for handling wrapped requests.

Subject: [PATCH] CFQ io scheduler updates

- Adjust slice values

- Instead of one async queue, one is defined per priority level. This
  prevents kernel threads (such as reiserfs/x and others) that run at
  higher io priority from conflicting with others. Previously, it was a
  coin toss what io prio the async queue got, it was defined by who
  first set up the queue.

- Let a time slice only begin, when the previous slice is completely
  done. Previously we could be somewhat unfair to a new sync slice, if
  the previous slice was async and had several ios queued. This might
  need a little tweaking if throughput suffers a little due to this,
  allowing perhaps an overlap of a single request or so.

- Optimize the calling of kblockd_schedule_work() by doing it only when
  it is strictly necessary (no requests in driver and work left to do).

- Correct sync vs async logic. A 'normal' process can be purely async as
  well, and a flusher can be purely sync as well. Sync or async is now a
  property of the class defined and requests pending. Previously writers
  could be considered sync, when they were really async.

- Get rid of the bit fields in cfqq and crq, use flags instead.

- Various other cleanups and fixes

Subject: [PATCH] CFQ io scheduler: scheduler switch oops

If cfq is managing a queue and a new scheduler is later selected, it is
possible for the cfqd unplug_work work to be queued after the kblockd
work struct has been flushed.  The problem is the ordering of
cfq_shutdown_timer_wq() and blk_put_queue() in cfq_put_cfqd().  The
latter may rearm the work, leaving cfq_kick_queue() with dead data.

Subject: [PATCH] USB: g_file_storage: export "stall" parameter

This patch changes the g_file_storage driver to make the "stall" module
parameter generally available; currently it is available only if the
testing version of the module has been configured.  It also fixes a typo
in a comment -- thanks, Pat!

Subject: [PATCH] USB: omap_udc updates (mostly cleanups)

Various USB patches, mostly for portability:

  - Fifo mode 1 didn't work previously (oopsed), so now it's fixed and
    (why not) defines even more endpoints for composite devices.

  - OMAP 1710 doesn't have an internal transceiver.

  - Small PM update:  if the USB link is suspended, don't disconnect on
    entry to deep sleep.

  - Be more correct about handling zero length control reads.  OMAP
    seems to mis-handle that protocol peculiarity though; best avoided.

  - Platform device resources (for UDC and OTG controllers) now use
    physical addresses, so /proc/iomem is more consistent.

  - Minor cleanups, notably (by volume) for "sparse" NULL warnings.

Subject: [PATCH] USB: Add isp116x-hcd USB host controller driver

This patch provides an "isp116x-hcd" driver for Philips'
ISP1160/ISP1161 USB host controllers.

The driver:
 - is relatively small, meant for use on embedded platforms.
 - runs usbtests 1-14 without problems for days.
 - has been in use by 6-7 different people on ARM and PPC platforms,
   running a range of devices including USB hubs.
 - supports suspend/resume of both the platform device and the root hub;
   supports remote wakeup of the root hub (but NOT the platform device)
   by USB devices.
 - does NOT support ISO transfers (nobody has asked for them).
 - is PIO-only.

Subject: [PATCH] USB: Fix oops at rmmod after failed probe in isp116x-hcd

This patch fixes an oops triggered at rmmod of isp116x-hcd
after the probe() has failed.

Also, it extends the error message printed, if the driver
cannot detect "Chip's Clock Ready" after a software reset.
As Ian Campbell recently reported, this happens if the
chip's H_WAKEUP pin is not pulled low during software reset.
Several people have already had this issue, hence the update
to the error message.

Also, extend the error message about the failed clock
detection after the software reset.

Subject: [PATCH] USB: turn a user mode driver error into a hard error

This patch turns a user mode driver error into a hard error, and updates
the relevant diagnostic slightly to help troubleshooting.  gphoto was
known to have this problem, hopefully it is now fixed (they have had
plenty of warning...)

This had been left as a soft error to give various user mode drivers a
change to be properly fixed, with the statement that starting in about
2.6.10 it would be changed.  It had been mostly safe as a soft error ...
but that can not be guaranteed.  Now that a year has passed, it's time to
really insist that the user mode drivers finally fix their relevant bugs.

Subject: [PATCH] USB UHCI: Add root hub states

This patch starts making some serious changes to the UHCI driver.
There's a set of private states for the root hub, and the internal
routines for suspending and resuming work completely differently, with
transitions based on the new states.  Now the driver distinguishes
between a privately auto-stopped state and a publicly suspended state,
and it will properly suspend controllers with broken resume-detect
interrupts instead of resetting them.

From a8bed8b6be75bc5a46aa599ab360d5f1db291c8f Mon Sep 17 00:00:00 2001
From: Alan Stern <stern@rowland.harvard.edu>
Date: Sat, 9 Apr 2005 17:29:00 -0400
Subject: [PATCH] USB UHCI: Add root-hub suspend/resume support

This patch implements (finally!) separate suspend and resume routines
for the root hub and the controller in the UHCI driver.  It also
changes the sequence used to reset the controller during initial
probing, so as to preserve the existing state during a Resume-From-Disk.
(This new sequence is what should be used in the PCI Quirks code for
early USB handoffs, incidentally.)  Lastly it adds a notion of the
controller being "inaccessible" while in a PCI low-power state, when
normal I/O operations shouldn't be allowed.

From 4daaa87c8f19c5f1978470e9e91b74d9e0fb0f8e Mon Sep 17 00:00:00 2001
From: Alan Stern <stern@rowland.harvard.edu>
Date: Sat, 9 Apr 2005 17:30:08 -0400
Subject: [PATCH] USB UHCI: Fix up loose ends

This patch tidies up a few loose ends left by the preceding patches.
It indicates the controller supports remote wakeup whenever the PM
capability is present -- which shouldn't cause any harm if the
assumption turns out to be wrong.  It refuses to suspend the
controller if the root hub is still active, and it refuses to resume
the root hub if the controller is suspended.  It adds checks for a
dead controller in several spots, and it adds memory barriers as
needed to insure that I/O operations are completed before moving on.

Actually I'm not certain the last part is being done correctly.  With
code like this:

	outw(..., ...);
	mb();
	udelay(5);

do we know for certain that the outw() will complete _before_ the
delay begins?  If not, how should this be written?

Subject: [PATCH] USB UHCI: Use root-hub IRQs while suspended

This patch, which has as478b as a prerequisite, enables the uhci-hcd
driver to take advantage of root-hub IRQs rather than polling during the
time it is suspended.  (Unfortunately the hardware doesn't support
port-change interrupts while the controller is running.)  It also turns
off the driver's private timer while the controller is suspended, as it
isn't needed then.  The combined elimination of polling interrupts and
timer interrupts ought to be enough to allow some systems to save a
noticeable amount of power while they are otherwise idle.

Subject: [PATCH] USB UHCI: improved reset handling

This patch improves the strategy uhci-hcd uses for performing controller
resets and checking whether they are needed.

	The HCRESET command doesn't affect the Suspend, Resume,
	or Reset bits in the port status & control registers, so
	the driver must clear them by itself.  This means the
	code to figure out how many ports there are has to be moved
	to an earlier spot in the driver.

	The R/WC bits in the USBLEGSUP register can be set by the
	hardware even in the absence of BIOS meddling with legacy
	support features.  Hence it's not a good idea to check them
	while trying to determine whether the BIOS has altered the
	controller's state.

Subject: [PATCH] USB UHCI: Add shutdown method

After all the discussion you might not be interested in this still, but
nevertheless here it is.  This patch adds a shutdown method to the
uhci-hcd driver.  Its prerequisite is the patch you wrote adding shutdown
support for PCI.

Subject: [PATCH] usbcore support for root-hub IRQ instead of polling

This is a revised version of an earlier patch to add support to usbcore
for driving root hubs by interrupts rather than polling.

There's a temporary flag added to struct usb_hcd, marking devices whose
drivers are aware of the new mechanism.  By default that flag doesn't get
set so drivers will continue to see the same polling behavior as before.
This way we can convert the HCDs one by one to use interrupt-based event
reporting, and the temporary flag can be removed when they're all done.

Also included is a small change to the hcd_disable_endpoint routine.
Although endpoints normally shouldn't be disabled while a controller is
suspended, it's legal to do so when the controller's driver is being
rmmod'ed.

Lastly the patch adds a new callback, .hub_irq_enable, for use by HCDs
where the root hub's port-change interrupts are level-triggered rather
than edge-triggered.  The callback is invoked each time khubd has finished
processing a root hub, to let the HCD know that the interrupt can safely
be re-enabled.

Subject: [PATCH] USB: usbtest updates

Updates to "usbtest" driver:

  * Improve some diagnostics.  One path that never generated diagnostics
    before should now generate two ... unless you hit a GCC bug that
    all my compilers seem to have, go figure.

  * Add suspend/resume support, so this behaves when the Linux host
    being used for testing suspends.

  * Don't test the "zero byte ep0 read" case unless real-world relevance
    for the testing is is irrelevant.

Subject: [PATCH] USB: PM support for zd1201

This patch enables power management (suspend, resume) support for zd1201.
It fixes problems after wakeup for me, but these problems did not appear
everytime without this patch.  it's a bit empirical, based on what the
usbnet does, so maybe not correct...  Maybe someone can give it a look
before it's applied.

My patch adding PM support for zd1201 didn't check for the device on
resume, which can oops if the device has been removed.

This patch fixes it.

Subject: [PATCH] usbcore: Remove hub_set_power_budget

This patch removes the hub_set_power_budget routine, which was used by a
couple of HCDs to indicate that the root hub was running on battery power.
In its place is a new field added to struct usb_hcd, which HCDs can set
before the root hub is registered.  Special-case code in the hub driver
knows to look at this field when configuring a root hub.

Subject: [PATCH] UHCI: Don't store device pointer in QH or TD

This patch simplifies the uhci-hcd driver by removing the device pointer
currently stored in the QH and TD structures.  Those pointers weren't
being used for anything other than to increment the device's reference
count, which is unnecessary since the device is used only when an URB
completes, and outstanding URBs take their own reference to the device.
As a useful side effect, this change means that uhci-hcd no longer needs
to have the root-hub device available in the start routine.

Subject: [PATCH] usbcore: register root hub in usb_add_hcd

This patch makes usbcore automatically allocate and register the root hub
device for a new host controller when the controller is registered.  This
way the HCDs don't all have to include the same boilerplate code.  As a
pleasant side benefit, the register_root_hub routine can now be made
static and not EXPORTed.

Subject: [PATCH] USB HCDs: no longer need to register root hub

This patch changes the host controller drivers; they no longer need to
register their root hubs because usbcore will take care of it for them.

From 340600ab4cf0cc41efd01a65af97ebb7d35a7f85 Mon Sep 17 00:00:00 2001

Subject: [PATCH] USB: rndis updates (mostly cleanup)

Some bugfixes and lots of cleanup (net code shrink):

  - On reset, force the RNDIS state machine its initial state

  - Hook up the RNDIS (outgoing) filters to the CDC mechanism

  - Lots of cleanup:
     * Eliminate duplicate copy of OID table;
     * Unify handlying of the OID "query" response data pointer;
     * Reduce code duplication for calculating query response lengths;
     * Remove some checks for "can't happen" errors;
     * Get rid of debugging #ifdefs by making the debug flag an integer level

Most of the patch, by volume, relates to those query response cleanups.
It incidentally shaves off a few hundred bytes of object code.

From 907cba35f7f24587f0eff60073e1f4e1e01c976d Mon Sep 17 00:00:00 2001
From: David Brownell <david-b@pacbell.net>
Date: Thu, 28 Apr 2005 13:48:09 -0700
Subject: [PATCH] USB: ethernet gadget updates (mostly cleanup)

Some cleanup for the the Ethernet part of the Ethernet/RNDIS gadget driver:

  - Remove remnants of ancient endpoint init logic; this is simpler, clearer

  - Save a smidgeon of space in the object file

  - Get rid of some #ifdeffery, mostly by using some newish inlines

  - Reset more driver state as part of USB reset

  - Remove a needless wrapper around an RNDIS call

  - Improve and comment the status interrupt handling:
      * RNDIS sometimes needs to queue these transfers (rarely in normal
        cases, but reproducibly while Windows was deadlocking its USB stack)
      * Mark requests as busy/not

  - Enable the SET_NETDEV_DEV() call; sysfs seems to behave sanely now

This is a net shrink of source code.

From 65111084c63d7674dc37833e8eb59cfdaa4d0bda Mon Sep 17 00:00:00 2001
From: David Brownell <david-b@pacbell.net>
Date: Thu, 28 Apr 2005 13:52:31 -0700
Subject: [PATCH] USB: more omap_udc updates (dma and omap1710)

More omap_udc updates:

  * OMAP 1710 updates
      - new UDC bit for clearing endpoint toggle, affecting CLEAR_HALT
      - new OTG bits affecting wakeup
  * Fix the bug Vladimir noted, that IN-DMA transfer code path kicks in
    for under 1024 bytes (not "up to 1024 bytes")
  * Handle transceiver setup more intelligently
      - use transceiver whenever one's available; this can be handy
        for GPIO based, loopback, or transceiverless configs
      - cleanup correctly after the "unrecognized HMC" case
  * DMA performance tweaks
      - allow burst/pack for memory access
      - use 16 bit DMA access most of the time on TIPB
  * Add workarounds for some DMA errata (not observed "in the wild"):
      - DMA CSAC/CDAC reads returning zero
      - RX/TX DMA config registers bit 12 always reads as zero (TI patch)
  * More "sparse" warnings removed, notably "changing" the SETUP packet
    to return data in USB byteorder (an API change, null effect on OMAP
    except for these warnings).

From 5742b0c95026c817d9c266174ca39a909e8d38ca Mon Sep 17 00:00:00 2001
From: Alan Stern <stern@rowland.harvard.edu>

Subject: [PATCH] USB dummy_hcd: Partial OTG emulation

Partial OTG support for dummy_hcd, mostly as a framework for further work.
It emulates the new OTG flags in the host and peripheral frameworks, if
that option is configured.  But it's incomplete:

  - Resetting the peripheral needs to clear the OTG state bits;
    a second enumeration won't work correctly.

  - This stops modeling HNP right when roles should switch the first time.
    It should probably disconnect, then set the usb_bus.is_b_host and
    usb_gadget.is_a_peripheral flags; then it'd enumerate almost normally,
    except for the role reversal.  Roles could then switch a second time,
    back to "normal" (with those flags cleared).

  - SRP should be modeled as "resume from port-unpowered", which is
    a state that usbcore doesn't yet use.

HNP can be triggered by enabling the OTG whitelist and configuring a
gadget driver that's not in that list; or by configuring Gadget Zero
to identify itself as the HNP test device.

Subject: [PATCH] USB: dummy_hcd: USB_PORT_FEAT changed to USB_PORT_STAT

This patch makes some cosmetic changes to dummy_hcd:

	Minor alterations of comments and whitespace.

	Replace USB_PORT_FEAT_xxx with USB_PORT_STAT_xxx.  This is
	appropriate as the values are stored in a status variable
	and they aren't feature indices.  Also it allows the
	elimination of a bunch of awkward bit shift operations.

Subject: [PATCH] USB dummy_hcd: Use separate pdevs for HC and UDC

This patch makes the dummy_hcd driver create separate platform devices for
the emulated host controller and emulated device controller.  This gives a
more accurate simulation and will permit testing of situations where only
one of the two devices is suspended.

This also changes the name of the host controller platform device to match
the name of the driver.  That way the normal platform bus probe mechanism
will handle binding the driver to the device.

Subject: [PATCH] USB dummy_hcd: Centralize link state computations

This patch adds to the dummy_hcd driver a new routine for keeping track of
all changes in the state of the emulated USB link.  The logic is now kept
in one spot instead of spread around, and it's easier to verify and
update the code.  The behavior of the port features has been corrected in
a few respects as well (for instance, if the POWER feature is clear then
none of the other features can be set).

Also added is support for the (relatively new) _connect() and
_disconnect() calls of the Gadget API.

Subject: [PATCH] USB dummy_hcd: Use root-hub interrupts instead of polling

This patch makes the dummy_hcd driver use emulated root-hub interrupts
instead of polling.  It's in the spirit of similar changes being made to
the other HCDs.

Subject: [PATCH] USB: Kconfig fixes for usb/gadget

This prevents gadget drivers from being selected when no controller has
been selected, by adding an additional boolean and depending on it.
It's mostly to help "allmodconfig".

Subject: [PATCH] USB: gadget driver updates (SETUP api change)

This updates most of the gadget framework to expect SETUP packets use
USB byteorder (matching the annotation in <linux/usb_ch9.h> and usage
in the host side stack):

  - definition in <linux/usb_gadget.h>
  - gadget drivers:  Ethernet/RNDIS, serial/ACM, file_storage, gadgetfs.
  - dummy_hcd

It also includes some other similar changes as suggested by "sparse",
which was used to detect byteorder bugs.

Subject: [PATCH] USB: net2280 updates (sparse, SETUP api change)

This is mostly "sparse" related updates, one of which was a missing
le32_to_cpu() should have affected big-endian hardware.

Notable is the API change:  setup packets are now provided in USB
byte order.  This affects only big-endian hardware, and the gadget
drivers have been updated in a separate patch.

Subject: [PATCH] USB: pxa2xx_udc updates

This has several small updates to the px2xx UDC driver:

  * small fixes from Eugeny S. Mints <emints@ru.mvista.com>
     - local_irq_save() around potential endpoint disable race
     - fix handling of enqueue to OUT endpoints (potential oops)
  * add shutdown() method to disable any D+ pullup
  * rename methods accessing raw signals, referencing the signals
  * describes itself as for "pxa25x", since pxa27x is different

Subject: [PATCH] USB: misc ehci updates

Various minor EHCI updates

   * Dump some more info in the debug dumps, notably the product
     description (e.g. chip vendor), BIOS handhake flags, and
     debug port status (when it's not managed by the HCD).

   * Minor updates to the BIOS handoff code:  always flag the HCD
     as owned by Linux (in case BIOS doesn't grab it "early"),
     and on the buggy-BIOS path always match the "early handoff"
     code and forcibly disable SMI IRQs.

   * For the disabled 64bit DMA support, there's now a constant
     to use for the mask; use it.

Subject: [PATCH] USB ATM: new usbatm core

Rework the core usbatm code: minidrivers (i.e. drivers for particular
modems) now register themselves with the usbatm core, supplying methods
for binding/unbinding etc.  The design was inspired by usb-serial and
usbnet.  At the same time, more common code from the speedtch and
cxacru (patch 3/5) drivers was generalized and moved into the core.  The
transmission and reception parts have been unified and simplified.  Since
this is a major change and I don't like underscores in file names,
usb_atm.[ch] has been renamed usbatm.[ch].

Many thanks to Roman Kagan, who did a lot of the coding.

+ *		usbatm_usb_send_data_context->urb to a pointer and adding code
+ *		to alloc and free it
+ *		- remove_wait_queue() added to usbatm_atm_processqueue_thread()
+ *
+ *  1.5:	- fixed memory leak when atmsar_decode_aal5 returned NULL.
+ *		(reported by stephen.robinson@zen.co.uk)
+ *
+ *  1.4:	- changed the spin_lock() under interrupt to spin_lock_irqsave()
+ *		- unlink all active send urbs of a vcc that is being closed.
+ *
+ *  1.3.1:	- added the version number
+ *
+ *  1.3:	- Added multiple send urb support
+ *		- fixed memory leak and vcc->tx_inuse starvation bug
+ *		  when not enough memory left in vcc.
+ *
+ *  1.2:	- Fixed race condition in usbatm_usb_send_data()

Date: Wed, 11 May 2005 20:20:40 +0200
Subject: [PATCH] USB ATM: port speedtch to new usbatm core

Port the speedtch driver to the new usbatm core.  The code is much
the same as before, just reorganized, though I threw in some minor
improvements (a new module parameter for choosing the altsetting,
more robust urb failure handling, ...) while I was there.

Subject: [PATCH] USB ATM: generic DSL modem driver xusbatm

Doesn't do any firmware loading etc, just transmission and reception.
The user needs to take care of modem initialization, and load the
module with parameters giving the endpoints to use and so forth.

Subject: [PATCH] USB ATM: reduce log spamming

Reduce the number of "unknown vpi/vci" debug messages to (usually) at most
one per-urb, rather than one per-cell.  This is only an issue when (a) many
packets come in but no connection is open; and (b) CONFIG_USB_DEBUG is set.

Subject: [PATCH] USB ATM: avoid oops on bind failure; plug memory leak

Zero the entire instance, not just the struct usbatm_data head.
Make sure the just allocated urb is freed if we fail to allocate
a buffer.  Based on a patch by Stanislaw W. Gruszka.

you seem to have applied the original, not the new improved one with
whiter teeth that uses kcalloc instead of kmalloc + memset.  Here's a
patch that goes on top of the one you applied.

Subject: [PATCH] USB: fix drivers/usb/gadget/ether.c compile error

This fixes a compile glitch with CONFIG_USB_ETH_RNDIS disabled, and
replaces some inline #ifdeffery (and other code) with inline functions
which can evaluate to constants.

Subject: [PATCH] USB UHCI: Detect invalid ports

This patch changes the way uhci-hcd detects valid ports.  The
specification doesn't mention any way to find out how many ports a
controller has, so the driver has to use some heuristics, reading the port
status and control register and deciding whether the value makes sense.
With this patch the driver will recognize a typical failure mode (all bits
set to one) for nonexistent ports and won't assume there are always at
least 2 ports -- such an assumption seems silly if the heuristics have
already shown that the ports don't exist.

buffer page pointer list of the iTD.  Particularly, a new page pointer
is needed every time when buffer data crosses a page boundary.

However, there is a bug in the allocation logic: the function does not
allocate a new entry when the current transaction is the first
transaction in the iTD (as indicated by first!=0).

The consequence is that, when the data of the first transaction begins
somewhere at the end of a page so that it actually does cross the page
boundary, no new page pointer is allocated.  This means that the data
at the end of the first transaction (beyond the page boundary) will be
accessed by the HC using the second page pointer, which is zero.
Furthermore, the first page pointer will be later overwritten by the
page pointers of the other transactions, which will garble it because
the value is or-ed into the iTD field.

All this particular check (for !first) does is cause incorrect
behaviour, so it should be entirely removed (and with it the variable
first that is not used for anything else).

Subject: [PATCH] USB Storage: endpoint toggles and reset delays

This patch does two things to help reset recovery.  It started life as
as496 and was rediffed by me.

First, the patch checks the result of a CLEAR_HALT request and doesn't reset the
endpoint's data toggle unless the request succeeded.

Second, it reduces the timeout for a device reset from 20 seconds to 5
seconds.

If all goes well, then I've finally figured quilt out and this patch should
apply cleanly.

Subject: [PATCH] USB Storage: retry hard errors

This patch started life as as527, and was rediffed by me.

Since the IDE interface doesn't convey much information about types of
errors, many USB-IDE adapters report all low-level errors with SK = 0x04,
which is supposed to be used only for non-recoverable errors.  As a result
the SCSI midlayer doesn't retry the command.  But quite often a retry
would succeed, whereas an unnecessary retry doesn't really hurt anything.

This patch uses a recently-implemented flag to tell the SCSI midlayer that
such hardware errors should be retried.

This fixes a build error on pxa25x processes with pxa2xx_udc and

        CONFIG_USB_ETH=m
        # CONFIG_USB_ETH_RNDIS is not set

The error is because on that CPU there's no status transfer support
except with RNDIS.  Workaround, enable the RNDIS support too.

since it only affects people doing selective (runtime) suspend/resume.

Subject: [PATCH] skge: function amd macro name change

The inlines and macro's needed some cleanup's and fixes:
 * change name of macro SKGEMAC_REG to SK_REG to better reflect usage
   and fix comments
 * ditto for SK_GEXM_REG -> SK_XMAC_REG and SKGEGMA_REG -> SK_GMA_REG

 * change skge_gm_ to just gm_ since it is just a local function and long
   names look ugly.
 * change skge_xm_ to just xm_
 * fix xm_write32 to write as two u16's with correct byte order
 * fix xm_outaddr to correctly use offset

Subject: [PATCH] skge: remove XM phy (untested code)

Remove support for the non-Broadcom genesis based boards. The code
is untested, and probably won't work as is. The newer boards are all
Yukon based, and only old Genesis board I can find uses Broadcom.

Subject: [PATCH] skge: make Genesis/Broadcom code work

Rewrite the code for handling the Broadcom PHY to something that
works. Remove link polling because Broadcom and Yukon don't need it.
When I wrote initial code, didn't have a genesis chipset based
board to test, so it was a non-working guess.

From 7e676d9136d89d0cdf661de4b9a5f8955af94e03 Mon Sep 17 00:00:00 2001
From: Stephen Hemminger <shemminger@osdl.org>
Date: Mon, 27 Jun 2005 11:33:13 -0700
Subject: [PATCH] skge: add PHY related debug messages

Cleanup messages (for debug) about PHY interrrupts, because when
user can't get driver working that is often the problem.
Use a consistent way of enabling interrupts by port.

Subject: [PATCH] ppc32: Bump PMU interrupt priority

The Power Management Unit on PowerMacs is very sensitive to timeouts during
async message exchanges.  It uses rather crude protocol based on a shift
register with an interrupt and is almost continuously exchanging messages with
the host CPU on laptops.

This patch adds a routine to the open_pic driver to be able to select a PMU
driver so that it bumps it's interrupt priority to above the normal level.

This will allow PMU interrupts to occur while another interrupt is pending,
and thus reduce the risk of machine beeing abruptly shutdown by the PMU due to
a timeout in PMU communication caused by excessive interrupt latency.  The
problem is very rare, and usually just doesn't happen, but it is still useful
to make things even more robust.

Subject: [PATCH] ppc32: remove obsolete macserial driver

The macserial driver has been obsoleted by the new pmac_zilog driver for a
while now and probably doesn't even work anymore on recent kernels.  This
patch removes it.

- * (most versions -- also with some Heathrow and Hydra ASICs) where a zero
- * at the input to the receiver becomes 'stuck' and locks up the receiver.
- * This problem can occur as a result of a zero bit at the receiver input

- *
- *	The SCC is initialized (hardware or software).
- *	A framing error is detected.
- *	The clocking option changes from synchronous or X1 asynchronous
- *		clocking to X16, X32, or X64 asynchronous clocking.
- *	The decoding mode is changed among NRZ, NRZI, FM0, or FM1.
- *
- * This workaround attempts to recover from the lockup condition by placing
- * the SCC in synchronous loopback mode with a fast clock before programming

Subject: [PATCH] ppc32: Remove CONFIG_PMAC_PBOOK

This patch removes CONFIG_PMAC_PBOOK (PowerBook support).  This is now
split into CONFIG_PMAC_MEDIABAY for the actual hotswap bay that some
powerbooks have, CONFIG_PM for power management related code, and just left
out of any CONFIG_* option for some generally useful stuff that can be used
on non-laptops as well.

Subject: [PATCH] IB/mthca: Use dma_alloc_coherent instead of
 pci_alloc_consistent

Switch all allocations of coherent memory from pci_alloc_consistent() to
dma_alloc_coherent(), so that we can pass GFP_KERNEL.  This should help when
the system is low on memory.

Subject: [PATCH] IB/mthca: Set RDMA/atomic capabilities correctly

mthca apparently had the meanings of the max_rd_atomic and max_dest_rd_atomic
QP attributes backwards.  max_rd_atomic limits the maximum number of
outstanding RDMA/atomic requests as an initiator (on a send queue), and
max_dest_rd_atomic specifies the resources allocated to handle RMDA/atomic
requests from the remote end of the connection.  We were programming our QP
context with these values swapped.

Subject: [PATCH] IB/mthca: Move mthca_is_memfree checks

Make mthca_table_put() and mthca_table_put_range() NOPs if the device is not
mem-free, so that we don't have to have "if (mthca_is_memfree())" tests in the
callers of these functions.  This makes our code more readable and
maintainable, and saves a couple dozen bytes of text in ib_mthca.ko as well.

Subject: [PATCH] IB/mthca: Align FW command mailboxes to 4K

Future versions of Mellanox HCA firmware will require command mailboxes to be
aligned to 4K.  Support this by using a pci_pool to allocate all mailboxes.
This has the added benefit of shrinking the source and text of mthca.

Subject: [PATCH] IB: Fix race in sa_query

Use a copy of the id we'll return to the consumer so that we don't
dereference query->sa_query after calling send_mad().  A completion may
occur very quickly and end up freeing the query before we get to do
anything after send_mad().

Subject: [PATCH] cciss: pci domain info pass 2

This is pass 2 of my patch to add pci domain info to an existing ioctl.  This
time I insert the domain between dev_fn and board_id as Willy suggested and
change the var to unsigned short to ease Christoph's concerns.  Although I
thought unsigned int was the correct var type for this.  I also thought it
didn't matter where I inserted it in the structure.

Subject: [PATCH] cciss: remove partition info from CCISS_GETLUNINFO

This patch fulfills a promise I made to Christoph sometime back.  I am
removing the partition info from the CCISS_GETLUNINFO ioctl as I was informed
my "driver had no damn business reading that structure." ;)

The application folks are to use /proc or /sys for partition info from now on.
 I am only aware of a few apps that use this ioctl and I'm not sure they ever
used the partition info.

Subject: [PATCH] ide: ide-generic, allow for capture of other unsupported
 devices

The ide-generic driver gives you DMA at bios tuned speed so can actually run a
lot of unsupported devices quite well.  It has a pci table so that it doesn't
grab disks owned by other drivers but no way to override this.  The patch adds
an option ide-generic-all which makes the driver grab everything going that is
IDE class.

The diff is messy because I put the special case as case 0 to make the if
conditional and long term maintenance easier.

This has been in Fedora for some time.

Subject: [PATCH] ide: fix the HPT366 driver layer

The highpoint driver is unreadable, buggy and crashes on some chipsets.  The
-ac one is more readable (but not ideal) and doesn't crash all over the place.
 Been in Fedora for some time.

Backported from the Fedora one to the old Bartlomiej IDE core.  No other
dependencies.

Subject: [PATCH] ide: fix crashes with hotplug serverworks

You can't install the base kernel on a Stratus box because of the overuse of
__init.  Affects both IDE layers identically.  It isn't the only misuser of
__init so more review of other drivers (or fixing ide_register code to know
about hotplug v non-hotplug chipsets) would be good.

Original issue found by Stratus and their patch was the inspiration for this
trivial one.

Subject: [PATCH] ide: it8212 backport for Bartlomiej IDE

This lets you throw out the iteraid stuff that has ended up back in due
to stupid goings on in the IDE world. Its the same heavily tested code
shipped in Fedora/Red Hat products but without the other dependancies on
the Bartlomiej IDE layer.

Pre-requisite: the ide-disk patch I sent to handle pure LBA devices.

Obviously you lose things like hot unplug with the Bartlomiej IDE layer
at the moment but that won't matter to most users.

The patch does the following
- Add IT8211/12 to pci_ids.h
- Add Makefile/Kconfig entry
- Add it8212 driver

No core IDE code is touched by this diff

Embedded system testing and the ability to force raid mode off by David
Howells

Made possible by the ite reference code, documentation and also several
clarifications and pieces of assistance provided by ITE themselves

+ *
+ *  The ITE8212 isn't exactly a standard IDE controller. It has two
+ *  modes. In pass through mode then it is an IDE controller. In its smart
+ *  mode its actually quite a capable hardware raid controller disguised
+ *  as an IDE controller. Smart mode only understands DMA read/write and
+ *  identify, none of the fancier commands apply. The IT8211 is identical
+ *  in other respects but lacks the raid mode.
+ *
+ *  Errata:
+ *  o	Rev 0x10 also requires master/slave hold the same DMA timings and
+ *	cannot do ATAPI MWDMA.
+ *  o	The identify data for raid volumes lacks CHS info (technically ok)
+ *	but also fails to set the LBA28 and other bits. We fix these in
+ *	the IDE probe quirk code.
+ *  o	If you write LBA48 sized I/O's (ie > 256 sector) in smart mode
+ *	raid then the controller firmware dies
+ *  o	Smart mode without RAID doesn't clear all the necessary identify
+ *	bits to reduce the command set to the one used
+ *
+ *  This has a few impacts on the driver
+ *  - In pass through mode we do all the work you would expect
+ *  - In smart mode the clocking set up is done by the controller generally
+ *    but we must watch the other limits and filter.
+ *  - There are a few extra vendor commands that actually talk to the
+ *    controller but only work PIO with no IRQ.
+ *
+ *  Vendor areas of the identify block in smart mode are used for the
+ *  timing and policy set up. Each HDD in raid mode also has a serial
+ *  block on the disk. The hardware extra commands are get/set chip status,
+ *  rebuild, get rebuild status.
+ *
+ *  In Linux the driver supports pass through mode as if the device was
+ *  just another IDE controller. If the smart mode is running then
+ *  volumes are managed by the controller firmware and each IDE "disk"
+ *  is a raid volume. Even more cute - the controller can do automated
+ *  hotplug and rebuild.
+ *
+ *  The pass through controller itself is a little demented. It has a
+ *  flaw that it has a single set of PIO/MWDMA timings per channel so
+ *  non UDMA devices restrict each others performance. It also has a
+ *  single clock source per channel so mixed UDMA100/133 performance
+ *  isn't perfect and we have to pick a clock. Thankfully none of this
+ *  matters in smart mode. ATAPI DMA is not currently supported.
+ *
+ *  It seems the smart mode is a win for RAID1/RAID10 but otherwise not.
+ *
+ *  TODO
+ *	-	ATAPI UDMA is ok but not MWDMA it seems

From 3c803e8e2f15d02c5ad0a3888eea2bbd31dc59c5 Mon Sep 17 00:00:00 2001
From: Linus Torvalds <torvalds@ppc970.osdl.org>
Date: Mon, 27 Jun 2005 17:49:45 -0700
Subject: Commit the manual part of the input layer merge.

git did actually warn me about the fact that I hadn't actually done an
"update-cache" on these two files, but the warning was at the bottom of
a list of all the files that _did_ change in the merge, so I never
noticed.  My bad.

In -mm1 the cardbus resources might be assigned in
pci_assign_unassigned_resources() pass. From your dmesg:
PCI: Bus 2, cardbus bridge: 0000:00:0b.0
  IO window: 00002000-00002fff
  IO window: 00003000-00003fff
  PREFETCH window: 12000000-13ffffff
  MEM window: 14000000-15ffffff

Then yenta_allocate_res() tries to assign these resources again and,
naturally, fails.

This adds check for already assigned cardbus resources.

Subject: [PATCH] pcmcia: hotplug event for PCMCIA devices

Export information to /sbin/hotplug for PCMCIA devices: card_id, manf_id,
func_id, bus_id (like pcmcia1.0) and crc32-hashes of the prod_id strings.

Why not the prod_id strings themselves?

a) They may contain all sorts of strange and difficult to handle characters,
   like " ".

b) It's impossible to pass multiple strings to userspace.

The one thing which surprises me in this patch that cis->Length needs to be
set to count+1.  Without it, it doesn't work, but with it, it doesn't make
sense to me.

Subject: [PATCH] pcmcia: allow function-ID based match

The "func_id"-based matching is very fuzzy and can lead to false positives.
Therefore, it should be tried to avoid relying on these matches.  Until
most/all existing func_id-based matches are replaced by
manf_id/card_id/prod_id matches (a patch which will ask to send the
appropriate card information to the PCMCIA mailing list will be added once
other, more pressing issues are adressed), we need to emulate cardmgr
behaviour by allowing func_id matches if no manf_id/card_id/prod_id match
occurs.  This can only be done in userspace because of modules possibly loaded
with long delays.  So, add a per-device sysfs file for this purpose.

Subject: [PATCH] pcmcia: cleanups

From: Adrian Bunk <bunk@stusta.de>

This patch contains the following cleanups:
- make needlessly global code static
- remove the following unneeded EXPORT_SYMBOL's:
  - ds.c: pcmcia_report_error
  - ds.c: pcmcia_bus_type

Subject: [PATCH] pcmcia: rescan bus always upon echoing into setup_done

Always rescan the devices upon echo'ing something to
available_resources_setup_done.  This is needed for proper "coldplug" support.

Subject: [PATCH] pcmcia: id_table for pcmciamtd.c

Add pcmcia_device_id table to pcmciamtd.  The binding of anonymus cards (i.e.
those who do neither report MANFID, CARDID, FUNCID nor product strings) is
protected by a new config option.

Subject: [PATCH] pcmcia id_table for sl811.cs

Catch up with some PCMCIA API changes:

 - Docs say that as of 2.6.11 the PCMCIA IRQInfo2 field is ignored,
   but it's not yet removed from the API; stop using it anyway.

 - As of 2.6.13 PCMCIA finally hotplugs and does driver binding
   without "cardmgr"; add a MODULE_DEVICE_TABLE to support this.

Subject: [PATCH] pcmcia: add some Documentation

Add some information useful for PCMCIA device driver authors to
Documentation/pcmcia/, and reference it in dmesg in case of hash mismatches.

Also add a reference to pcmciautils to Documentation/Changes.  With recent
changes, you don't need to concern yourself with pcmcia-cs even if you have
PCMCIA hardware, so the example above the list needed to be adapted as well.

-    of the device.  unbind_request() deletes a driver instance.

-    It is normally called by Driver Services after it has identified
-    a newly inserted card.  An instance of that driver will then be
-    eligible to register as a client of this socket.
-
-    Register_client() uses the dev_info_t handle to match the
-    caller with a socket.  The driver must have already been bound

+    bind_request() and bind_device() are merged by now. Register_client()
+    is called right at the end of bind_request(), during the driver's
+    ->attach() call. Individual descriptions:
+
+    bind_request() connects a socket to a particular client driver.
+    It looks up the specified device ID in the list of registered
+    drivers, binds it to the socket, and tries to create an instance
+    of the device.  unbind_request() deletes a driver instance.
+
+    Bind_device() associates a device driver with a particular socket.
+    It is normally called by Driver Services after it has identified
+    a newly inserted card.  An instance of that driver will then be
+    eligible to register as a client of this socket.
+
+    Register_client() uses the dev_info_t handle to match the
+    caller with a socket.  The driver must have already been bound
+    to a socket with bind_device() -- in fact, bind_device()
+    allocates the client structure that will be used.

Subject: [PATCH] pcmcia: use request_region in i82365

      randy_dunlap <rdunlap@xenotime.net>

Convert deprecated check_region() calls to request/release region.
Add return value check on one request_region().

I suspect that it may do an extra release_region(), which should
generate a warning message from the kernel.

Subject: [PATCH] pcmcia: 8 and 16 bit access for static_map

The PCMCIA card services layer is never setting the i/o map attributes when
SS_CAP_STATIC_MAP is specified.  Net result, sockets' set_io_map() calls
always see requests with most flags clear, meaning 8 bit access.

For hardware that always autosizes, that won't matter; and all current
STATIC_MAP drivers ignore those attributes.  A new driver (for at91rm9200)
suffers badly from this, since this forces everything into 8 bit mode and
that breaks both (a) cards requiring 16 bit access, and (b) ide-cs; but of
course 8-bit cards work OK (as does accessing card attributes).

So this patch arranges to pass the attributes down, matching the behavior
for non-static mappings (using the first/only I/O window).

Subject: [PATCH] ACPI-based PCI resources: PCMCIA bugfix, but resources
 missing in trees

Don't auto-configure yenta sockets for PCMCIA devices if it is connected to
the root PCI bus on the x86 or x86_64 architectures.  Previously, this was
handled by the "ioport_resource"/"iomem_resource" check a few lines below,
but with the new ACPI-based resource handling this doesn't catch all cases
any longer.

pci-yenta-cardbus-fix.patch and this patch should solve the initialization
time trouble.  However, the ACPI-based PCI resource handling is badly
broken, IMHO:

- many resources of devices don't show up in the resource trees (
  /proc/iomem and /proc/ioports) any longer. This means that PCMCIA, but
  also possibly other subsystems (ISA, PnP, ...) do not know which resources
  it cannot use.

- verify_root_windows() should fail if there are no iomem _or_ ioport
  resources, not only if there are no iomem _and_ ioport resources.

 mask

The amd8111e driver directly assigns the DMA mask to the dma_mask
member of the struct pci_dev instead of using pci_set_dma_mask(). This
makes the call to pci_dma_supported() redundant as pci_set_dma_mask()
does this check.

I do not own this device so I only compile-tested this patch.

This patch lengthens the delay between DET setting and clearing for
COMMRESET from 400us to 1ms.  I couldn't find any requiremen regarding
the duration of COMMRESET in SATA I/II specs but AHCI-1.1 10.4.2
states that it should be at least 1ms.

Subject: [PATCH] acpi bridge hotadd: ACPI based root bridge hot-add

When you hot-plug a (root) bridge hierarchy, it may have p2p bridges and
devices attached to it that have not been configured by firmware.  In this
case, we need to configure the devices before starting them.  This patch
separates device start from device scan so that we can introduce the
configuration step in the middle.

I kept the existing semantics for pci_scan_bus() since there are a huge number
of callers to that function.

Also, I have no way of testing the changes I made to the parisc files, so this
needs review by those folks.  Sorry for the massive cross-post, this touches
files in many different places.

Subject: [PATCH] acpi bridge hotadd: Prevent duplicate bus numbers when
 scanning PCI bridge

When hot-plugging a root bridge, as we try to assign bus numbers we may find
that the hotplugged hieratchy has more PCI to PCI bridges (i.e.  bus
requirements) than available.  Make sure we don't step over an existing bus

When a pci child bus is created, add it to the parent's children list
immediately rather than waiting till pci_bus_add_devices().  For hot-plug
bridges/devices, pci_bus_add_devices() may be called much later, after they
have been properly configured.  In the meantime, this allows us to use the
normal pci bus search functions for the hot-plug bridges/buses.

Subject: [PATCH] acpi bridge hotadd: Make the PCI remove routines safe for
 failed hot-plug

When a root bridge hierarchy is hot-plugged, resource requirements for the new
devices may be greater than what the root bridge is decoding.  In this case,
we want to remove devices that did not get needed resources.  These devices
have been scanned into bus specific lists but not yet added to the global
device list.  Make sure the pci remove functions can handle this case.

Subject: [PATCH] acpi bridge hotadd: Remove hot-plugged devices that could not
 be allocated resources

When hot-plugging an I/O hierarchy that contains many bridges and leaf
devices, it's possible that there are not enough resources to start all the
device present.  If we fail to assign a resource, clear the corresponding
value in the pci_dev structure, so other code can take corrective action.

Create new interfaces to recursively add an acpi namespace object to the acpi

ACPI based hotplug of a root bridge hierarchy where the add operation must be
performed first and the start operation must be performed separately after the
hot-plugged devices have been properly configured.

Subject: [PATCH] acpi hotplug: convert acpiphp to use generic resource code

This patch converts acpiphp to use the generic PCI resource assignment code.
It's quite large, but most of it is deleting the acpiphp_pci and acpiphp_res
files.  It's tested on an hp Integrity rx8620 (which won't work without this
patch).  Testers with other hardware welcomed.

Subject: [PATCH] acpi hotplug: clean up notify handlers on acpiphp unload

A root bridge may not have directly attached hotpluggable slots under it.
Instead, it may have p2p bridges with slots under it.  In this case, we need
to clean up the p2p bridges and slots properly too.  Patch below applies on
top of the original patch, and fixes this problem.  Without this, acpiphp
leaves behind notify handlers on module unload, and subsequent module load
attempts don't work properly too.  Patch was tested on an ia64 Tiger4 box.

Subject: [PATCH] acpi hotplug: fix slot power-down problem with acpiphp

Earlier I reported that Matthew's acpiphp rewrite had problem in powering down
slot on my i386 system.  The following patch is needed to get the acpiphp
rewrite properly powering down the slot.

Subject: [PATCH] acpi hotplug: decouple slot power state changes from physical
 hotplug

Current acpiphp code does not distinguish between the physical presence and
power state of a device/slot.  That is, if a device has to be disabled, it
also tries to physically ejects the device.  This patch decouples power state
from physical presence.  You can now echo to the corresponding sysfs power
control file to repeatedly enable and disable a device without having to
physically re-insert it.

Subject: [PATCH] PCI: fix-pci-mmap-on-ppc-and-ppc64.patch

This is an updated version of Ben's fix-pci-mmap-on-ppc-and-ppc64.patch
which is in 2.6.12-rc4-mm1.

It fixes the patch to work on PPC iSeries, removes some debug printks
at Ben's request, and incorporates your
fix-pci-mmap-on-ppc-and-ppc64-fix.patch also.

Originally from Benjamin Herrenschmidt <benh@kernel.crashing.org>

This patch was discussed at length on linux-pci and so far, the last
iteration of it didn't raise any comment.  It's effect is a nop on
architecture that don't define the new pci_resource_to_user() callback
anyway.  It allows architecture like ppc who put weird things inside of
PCI resource structures to convert to some different value for user
visible ones.  It also fixes mmap'ing of IO space on those archs.

Mostly just cleans up the irq handling logic to be smaller and a bit more

Subject: [PATCH] cpqphp: fix oops during unload without probe

drivers/pci/hotplug/cpqphp_core.c calls cpqphp_event_start_thread()
in one_time_init(), which is called whenever the hardware is probed.
Unfortunately, cpqphp_event_stop_thread() is *always* called when
the module is unloaded. If the hardware is never probed, then
cpqphp_event_stop_thread() tries to manipulate a couple of
uninitialized mutexes.

Subject: [IA64-SGI] pcdp: add PCDP pci interface support

Resend 2 with changes per Bjorn Helgaas comments.  Changes from original:

+ Change globals to vga_console_iobase/vga_console_membase and make them
  unconditional.
+ Address style-related comments.

Patch to extend the PCDP vga setup code to support PCI io/mem translations
for the legacy vga ioport and ram spaces on architectures (e.g. altix) which
need them.

Summary of the changes:

drivers/firmware/pcdp.c
drivers/firmware/pcdp.h
-----------------------
+ add declaration for the spec-defined PCI interface struct (pcdp_if_pci)
  as well as support macros.

+ extend setup_vga_console() to know about pcdp_if_pci and add a couple of
  globals to hold the io and mem translation offsets if present.

arch/ia64/kernel/setup.c
------------------------
+ tweek early_console_setup() to allow multiple early console setup routines
  to be called.

include/asm-ia64/vga.h
----------------------
+ make VGA_MAP_MEM vga_console_membase aware

Subject: [PATCH] ll_rw_blk: prevent huge request allocations

Currently we cap request allocations at q->nr_requests, but we allow a
batching io context to allocate up to 32 more (default setting).  This
can flood the queue with request allocations, with only a few batching
processes.  The real fix would be to limit the number of batchers, but
as that isn't currently tracked, I suggest we just cap the maximum
number of allocated requests to eg 50% over the limit.

This was observed in real life, users typically see this as vmstat bo
numbers going off the wall with seconds of no queueing afterwards.
Behaviour this bursty is not beneficial.

Subject: [NET]: Remove gratuitous use of skb->tail in network drivers.

Many drivers use skb->tail unnecessarily.

In these situations, the code roughly looks like:

	dev = dev_alloc_skb(...);

	[optional] skb_reserve(skb, ...);

	... skb->tail ...

But even if the skb_reserve() happens, skb->data equals
skb->tail.  So it doesn't make any sense to use anything
other than skb->data in these cases.

Another case was the s2io.c driver directly mucking with
the skb->data and skb->tail pointers.  It really just wanted
to do an skb_reserve(), so that's what the code was changed
to do instead.

Another reason I'm making this change as it allows some SKB
cleanups I have planned simpler to merge.  In those cleanups,
skb->head, skb->tail, and skb->end pointers are removed, and
replaced with skb->head_room and skb->tail_room integers.

Subject: [PATCH] drivers/char/tipar.c: off by one array access

In the setup function, the delay variable is initialized with ints[2],
but ints is declared as:
	int ints[2];

Since the module parameter should correspond to:
	tipar=timeout,delay

I suppose that the following patch fix the problem.

Subject: [PATCH] coverity: ipmi_msghandler() channels array overrun fix

We fix the check in 1084, which was

1084 			if (addr->channel > IPMI_NUM_CHANNELS) {
1085 				spin_lock_irqsave(&intf->counter_lock, flags);
1086 				intf->sent_invalid_commands++;
1087 				spin_unlock_irqrestore(&intf->counter_lock, flags);
1088 				rv = -EINVAL;
1089 				goto out_err;
1090 			}

addr->channel is used in

1092 			if (intf->channels[addr->channel].medium

Definitions involved:

221  		struct ipmi_channel channels[IPMI_MAX_CHANNELS];

134  	#define IPMI_MAX_CHANNELS       8

In /linux-2.6.12-rc6/include/linux/ipmi.h

Subject: [PATCH] coverity: tty_ldisc_ref return null check

We add a check of the return value of tty_ldisc_ref(), which
is checked 7 out of 8 times, e.g.:

149  		ld = tty_ldisc_ref(tty);
150  		if (ld != NULL) {
151  			if (ld->set_termios)
152  				(ld->set_termios)(tty, &old_termios);
153  			tty_ldisc_deref(ld);
154  		}

This defect was found automatically by Coverity Prevent, a static analysis
tool.

(akpm: presumably `ld' is never NULL.  Oh well)

Subject: [PATCH] blk: __make_request efficiency

In the case where the request is not able to be merged by the elevator, don't
retake the lock and retry the merge mechanism after allocating a new request.

Instead assume that the chance of a merge remains slim, and now that we've
done most of the work allocating a request we may as well just go with it.

Also be rid of the GFP_ATOMIC allocation: we've got working mempools for the
block layer now, so let's save atomic memory for things like networking.

Lastly, in get_request_wait, do an initial get_request call before going into
the waitqueue.  This is reported to help efficiency.

Subject: [PATCH] blk: light iocontext ops

get_io_context needlessly turned off interrupts and checked for racing io
context creations.  Both of which aren't needed, because the io context can
only be created while in process context of the current process.

Also, split the function in 2.  A light version, current_io_context does not
elevate the reference count specifically, but can be used when in process
context, because the process holds a reference itself.

Subject: [PATCH] v4l: tuner improvements

*tuner-core.c:
- some tuner_info msgs will be generated only if insmod opt
        tuner_debug enabled.
- Implemented tuner-core support for VIDIO_S_TUNER to allow
        changing mono/stereo mode
- Remove unneeded config options.
- I2C_CLIENT_MULTI option removed.
- support for Philips FMD12ME hybrid tuner
- allow to initialize with another tuner
- Move PHILIPS_FMD initialization code to set_type function,

* tda8290:

- Fix dumb error in tda8290 tunning.
- Radio tuner uses high-precision step instead of 62.5 KHz.

*tea5767.c:
- tuner_info msgs will be generated only if insmod tuner option
        tuner_debug enabled.
- some cleanups for better reading.
- Radio tuner uses high-precision step instead of 62.5 KHz.
- Changing radio mode stereo/mono for tea5767 working.

*tuner-simple.c:
- TNF9533-D/IF UHF fixup.
- Radio tuners now uses high-precision step instead of 62.5 KHz.

*mt20xx.c:
        - Radio tuner uses high-precision step instead of 62.5 KHz.

*tda9887.c:
        - tab and blank spaces corrections.

Subject: [PATCH] v4l: bttv new insmod parameters

* bttv-driver.c, bttvp.h:

- New bttv module params:

- uv_ratio : allow a ratio of saturation between u and v. If you
        have a ratio of 40 and a saturation of 100, usat will be 80 and
        vstat 120. Useful to correct a bad color balance.
- full_luma_range : provide a better contrast in using the full
        range 0-253 of values instead of 16-253.
- coring : to have a better black level.
- radio range is now defined on tuner-core.c. Cleaning up.

* bttvp.h:

- Fix gcc 4.0 compilation

Subject: [PATCH] Serial: Adjust serial locking

This patch changes the way serial ports are locked when getting modem
status.  This change is necessary because we will need to atomically
read the modem status and take action depending on the CTS status.

get_request is now expected to be holding on to queue_lock, with interrupts
disabled, when it returns NULL; but one path forgot that, causing all kinds
of nastiness under swap load - badness backtraces, strange failures, BUGs.

Subject: [PATCH] Don't fill up log with atxp1 vcore messages change message

I am using the atxp1 module to change vcore on my NForce2 via userspace
daemon (see punnoor.de).

Currently the atxp1 module will write to the log on every vcore change,
thus filling up my log - which I don't want.  I am no kernel coder, but
I guess, this one-liner will change this behaviour in a wanted way, ie
output will be made for debug purposes only.

Patch from Nicolas Pitre

Those are big, slow and generally not recommended for kernel code.
They are even not present on i386.  So it should be concluded that
one could as well get away with do_div() alone.

characters to send and want to only disable the TX interrupt,
allow that scenario.

Remove legacy ISA serial ports for Accent, Boca, Fourport, Hub6 and MCA
from the architecture specific serial.h include.

The only ports which remain in asm-*/serial.h are the platform specific
entries.  These should really be converted by platform maintainers to
use a platform device, such as can be found in
arch/arm/mach-footbridge/isa.c

Subject: [PATCH] driver core: Add the ability to bind drivers to devices from
 userspace

This adds a single file, "bind", to the sysfs directory of every driver
registered with the driver core.  To bind a device to a driver, write
the bus id of the device you wish to bind to that specific driver to the
"bind" file (remember to not add a trailing \n).  If that bus id matches
a device on that bus, and it does not currently have a driver bound to
it, the probe sequence will be initiated with that driver and device.

Note, this requires that the driver itself be willing and able to accept
that device (usually through a device id type table).  This patch does
not make it possible to override the driver's id table.

Subject: [PATCH] driver core: change bus_rescan_devices to return void

No one was looking at the return value of bus_rescan_devices, and it
really wasn't anything that anyone in the kernel would ever care about.
So change it which enabled some counting code to be removed also.

Subject: [PATCH] Serial: Fix small CONFIG_SERIAL_8250_NR_UARTS

If CONFIG_SERIAL_8250_NR_UARTS is smaller than the array size in
asm/serial.h, we trampled on memory which wasn't ours.  Take our
big boots away by limiting the number of ports initialised to the
smaller of ...NR_UARTS and the array size.

Patch from Catalin Marinas

This patch calculates the AFS partition length by expanding the image
length information to the nearest erase block boundary. This
eliminates the problems with JFFS2 erasing the footer.

Subject: [PATCH] PCI: handle subtractive decode pci-pci bridge better

With the number of PCI bus resources increased to 8, we can
handle the subtractive decode PCI-PCI bridge like a normal
bridge, taking into account standard PCI-PCI bridge windows
(resources 0-2). This helps to avoid problems with peer-to-peer DMA
behind such bridges, poor performance for MMIO ranges outside bridge
windows and prefetchable vs. non-prefetchable memory issues.

To reflect the fact that such bridges do forward all addresses to
the secondary bus (transparency), remaining bus resources 3-7 are
linked to resources 0-4 of the primary bus. These resources will be
used as fallback by resource management code if allocation from
standard bridge windows fails for some reason.

Subject: [PATCH] PCI: pci_assign_unassigned_resources() on x86

- Add sanity check for io[port,mem]_resource in setup-bus.c. These
  resources look like "free" as they have no parents, but obviously
  we must not touch them.
- In i386.c:pci_allocate_bus_resources(), if a bridge resource cannot be
  allocated for some reason, then clear its flags. This prevents any child
  allocations in this range, so the setup-bus code will work with a clean
  resource sub-tree.
- i386.c:pcibios_enable_resources() doesn't enable bridges, as it checks
  only resources 0-5, which looks like a clear bug to me. I suspect it
  might break hotplug as well in some cases.

Subject: [PATCH] PCI: clean up dynamic pci id logic

The dynamic pci id logic has been bothering me for a while, and now that
I started to look into how to move some of this to the driver core, I
thought it was time to clean it all up.

It ends up making the code smaller, and easier to follow, and fixes a
few bugs at the same time (dynamic ids were not being matched
everywhere, and so could be missed on some call paths for new devices,
semaphore not needed to be grabbed when adding a new id and calling the
driver core, etc.)

I also renamed the function pci_match_device() to pci_match_id() as
that's what it really does.

Subject: [PATCH] PCI: Remove newline from pci MODALIAS variable

the pci core sends out a hotplug event variable MODALIAS with a trailing
newline. This is inconsistent with all other event variables and breaks
some hotplug tools. This patch removes the said newline.

Subject: [PATCH] pci: cleanup argument comments for pci_{save,restore}_state

The buffer arguments have been removed from pci_{save,restore}_state.
The comment blocks for those functions should reflect that.

Subject: [PATCH] gregkh-pci-pci-assign-unassigned-resources fix

It seems that X86 architectures in general need the setup-bus.o
not just those with HOTPLUG.  This avoids the following error on
X86_NUMAQ and x86_64:

    arch/i386/pci/built-in.o(.init.text+0x15a6): In function `pcibios_init':
    : undefined reference to `pci_assign_unassigned_resources'

Subject: [PATCH] amd74xx: support MCP55 device IDs

From: Rob Punkunus <rpunkunus@nvidia.com>

Rob Punkunus recently submitted a patch to enable support for MCP51/MCP55 in
the amd74xx driver. This patch was whitespace-corrupted and didn't apply to
2.6.12 since MCP51 support was merged in the 2.6.12-rc series.

Gentoo would like to support this hardware for our upcoming release media, so
I fixed the patch, and here it is :)

 disabled

Patch from Ben Dooks

The request_irq() function is called by s3c24xx uart driver with
the local IRQs disabled. The request_irq() function can allocate
memory via kmalloc(), and this may sleep causing a warning about
sleeping in an invalid context.

Subject: [SHAPER]: Switch to spinlocks.

Dave, you were right and the sleeping locks in shaper were
broken. Markus Kanet noticed this and also tested the patch below that
switches locking to spinlocks.

Subject: [PATCH] ppc32: add Freescale MPC885ADS board support

This patch adds the Freescale MPC86xADS board support.  The supported
devices are SMC UART and 10Mbit ethernet on SCC1.

The manual for the board says that it "is compatible with the MPC8xxFADS
for software point of view".  That's why this patch extends FADS instead of
introducing a new platform.

FEC is not supported as the "combined FCC/FEC ethernet driver" driver by
Pantelis Antoniou should replace the current FEC driver.
