Subject: [AGPGART] Drop duplicate setting of info->mode in agp_copy_info()

backend support.  It's clearly incorrect to overwrite info->mode after
we just went to lengths to determine which bits to mask out.

Subject: [WATCHDOG] correct sysfs name for watchdog devices

While looking for possible candidates for our udev.rules package,
I found a few odd ->name properties. /dev/watchdog has minor 130
according to devices.txt. Since all watchdog drivers use the
misc_register() call, they will end up in /sys/class/misc/$foo.
udev may create the /dev/watchdog node if the driver is loaded.
I dont have such a device, so I cant test it.
The drivers below provide names with spaces and even with / in it.
Not a big deal, but apps may expect /dev/watchdog.

Subject: [WATCHDOG] s3c2410 watchdog power management

Patch from Dimitry Andric <dimitry.andric@tomtom.com>, updated
by Ben Dooks <ben-linux@fluff.org>. Patch is against 2.6.11-mm2

Add power management support to the s3c2410 watchdog, so that
it is shut-down over suspend, and re-initialised on resume.

Also add Dimitry to the list of authors.

Subject: [WATCHDOG] w83627hf_wdt.c-initialized_bios_bug

Attached is a small update to the w83627hf watchdog driver
to initialise appropriately if it was already initialised
in the BIOS. On tyan motherboards for e.g. you can init
the watchdog to 4 mins, then when the driver is loaded it
sets the watchdog to "seconds" mode, and then machine will
reboot within 4 seconds. So this patch resets the timeout
to the configured value if the watchdog is already running.

Subject: [WATCHDOG] softdog-timer-running-oops.patch

The softdog watchdog timer has a bug that can create an oops:

1.  Load the module without the nowayout option.
2.  Open the driver and close it without writing 'V' before close.
3.  Unload the module.  The timer will continue to run...
4.  Oops happens when timer fires.

Reported Sun, 10 Oct 2004, by Michael Schierl <schierlm@gmx.de>

Fix is easy: always take a reference on the module on open.
Release it only when the device is closed and no timer is running.
Tested on 2.6.13-rc6 using the soft_noboot option.  While the
timer is running and the device is closed, the module use count
stays at 1.  After the timer fires, it drops to 0.  Repeatedly
opening and closing the driver caused no problems.  Please apply.

2) First 10 ports (ttya0...ttya9) clash with the legacy pty driver.

This patch changes the driver name to "ttyMX".

Subject: [PATCH] tpm_infineon: Bugfix in PNPACPI-handling

This patch corrects the PNP-handling inside the tpm-driver
and some minor coding style bugs.
Note: the pci-device and pnp-device mixture is currently necessary,
since the used "tpm"-interface requires a pci-dev in order to register
the driver. This will be fixed within the next iterations.

Subject: [PATCH] ppc32: Added support for the Book-E style Watchdog Timer

PowerPC 40x and Book-E processors support a watchdog timer at the processor
core level.  The timer has implementation dependent timeout frequencies
that can be configured by software.

One the first Watchdog timeout we get a critical exception.  It is left to
board specific code to determine what should happen at this point.  If
nothing is done and another timeout period expires the processor may
attempt to reset the machine.

Command line parameters:
  wdt=0 : disable watchdog (default)
  wdt=1 : enable watchdog

  wdt_period=N : N sets the value of the Watchdog Timer Period.

  The Watchdog Timer Period meaning is implementation specific. Check
  User Manual for the processor for more details.

This patch is based off of work done by Takeharu Kato.

Subject: [MOXA]: Fix this driver properly.

Actually, proper fix of that breakage is embarrassingly simple - it's yet
another gratitious leftover include of asm/segment.h, so incremental to the
previos would be removal of that BROKEN and removal of bogus include from
mxser.c itself.

Subject: [SPARC64]: Kconfig fix (GEN_RTC dependencies)

Yet another architecture not coverd by GEN_RTC - sparc64 never picked
it until now and it doesn't have asm/rtc.h to go with it, so it
wouldn't compile anyway (or have these ioctls in the user-visible
headers, for that matter).

FWIW, I'm very tempted to introduce ARCH_HAS_GEN_RTC and have it set
in arch/*/Kconfig for architectures that know what to do with this
stuff - for something supposedly generic the list of architectures
where it doesn't work is getting too long...

Subject: [PATCH] sonypi SPIC initialisation fix

Newer Sony VAIO models (VGN-S480, VGN-S460, VGN-S3XP etc) use a new method to
initialize the SPIC device.  The new way to initialize (and disable) the
device comes directly from the AML code in the _CRS, _SRS and _DIS methods
from the DSDT table.  This patch adds support for the new models.

Subject: [PATCH] Console blanking locking fix

I've had WARN_CONSOLE_UNLOCKED warnings when calling TIOCLINUX
TIOCL_BLANKSCREEN and TIOCL_UNBLANKSCREEN.

(I'm blind and I use a braille display.  I use those functions to blank my
laptop's screen so people don't read it, and hopefully to conserve power.)

The warnings are from these places:
do_blank_screen at drivers/char/vt.c:2754 (Not tainted)
save_screen at drivers/char/vt.c:575 (Not tainted)
do_unblank_screen at drivers/char/vt.c:2822 (Not tainted)
set_palette at drivers/char/vt.c:2908 (Not tainted)

At a glance I would think the following patch ought to fix that.  Tested on
one machine.  Could you please tell me if this is correct and/or forward
the patch where appropriate...

Subject: [PATCH] vt: fix possible memory corruption in complement_pos

Based on a patch from Andr Pereira de Almeida <andre@cachola.com.br>

It might be possible for the saved pointer (*p) to become invalid in
between vc_resizes, so saving the screen offset instead of the screen
pointer is saner.

This bug is very hard to trigger though, but Andre probably did, if he's
submitting this patch.  Anyway, with Andre's patch, it's still possible for
the offsets to be still illegal, if the new screen size is smaller than the
old one.  So I've also added checks if the offsets are still within the
screenbuffer size.

Subject: [PATCH] hpet: fix drift and url

The HPET driver is using a parts per second drift factor instead of the
standard parts per million drift the time interpolator code expects.  This
patch fixes that problem and updates the URL for the HPET spec.

Subject: [PATCH] ipmi: add per-channel IPMB addresses

IPMI allows multiple IPMB channels on a single interface, and each channel
might have a different IPMB address.  However, the driver has only one IPMB
address that it uses for everything.  This patch adds new IOCTLS and a new
internal interface for setting per-channel IPMB addresses and LUNs.  New
systems are coming out with support for multiple IPMB channels, and they are
broken without this patch.

Subject: [PATCH] ipmi: OEM flag handling and hacks for some Dell machines

The ipmi driver does not have a way to handle firmware-generated events
which have the OEM[012] Data Available flags set.  In such a case, the
SMS_ATN bit may never get cleared by firmware, leaving the driver looping
infinitely but never able to make any progress.

This patch first simplifies storage and use of the data returned from an
IPMI Get Device ID command.

It then creates a new per-OEM handler hook, which should know how to handle
events with the OEM[012] Data Available flags set.  It then uses this to
implement a workaround for IPMI 1.5-capable Dell PowerEdge servers which
are susceptable to setting the OEM[012] Data Available flags when the
driver can't handle it.

Subject: [PATCH] ipmi: clean up versioning of the IPMI driver

This adds MODULE_VERSION, MODULE_DESCRIPTION, and MODULE_AUTHOR tags to the
IPMI driver modules.  Also changes the MODULE_VERSION to remove the
prepended 'v' on each value, consistent with the module versioning policy.

This patch also removes all the version information from everything except
the ipmi_msghandler module.

Subject: [PATCH] ipmi: fix panic ipmb response

The "null message handler" in the IPMI driver is used in startup and panic
situations to handle messages.  It was only designed to work with messages
from the local management controller, but in some cases it was used to get
messages from remote managmenet controllers, and the system would then
panic.  This patch makes the "null message handler" in the IPMI driver more
general so it works with any kind of message.

Subject: [PATCH] ipmi: add hacks for IPMI chassis poweroff for certain Dell
 servers

This patch allows Dell servers with IPMI controllers that predate IPMI 1.5
to use the standard poweroff or powercycle commands.  These systems
firmware don't set the chassis capability bit in the Get Device ID, but
they do implement the standard poweroff and powercycle commands.

Tested on RHEL3 kernel 2.4.21-20.ELsmp on a PowerEdge 2600.  The standard
ipmi_poweroff driver cannot drive these systems.  With this patch, they
power off or powercycle as expected.

Subject: [PATCH] ipmi poweroff: fix chassis control

The IPMI power control function proc_write_chassctrl was badly written, it
directly used userspace pointers, it assumed that strings were NULL
terminated, and it used the evil sscanf function.  This converts over to
using the sysctl interface for this data and changes the semantics to be a
little more logical.

Removed gratuitous includes of asm/serial.h in synklinkmp and ip2main.
Allows to remove the rest of "broken on sparc32" in drivers/char - this
stuff doesn't break the build anymore.  Since it got zero testing, it almost
certainly won't work there, though...

Subject: [PATCH] pty_chars_in_buffer oops fix

The idea of this patch is to lock both sides of a ptmx/pty pair during line
discipline changing.  This is needed to ensure that say a poll on one side of
the pty doesn't occur while the line discipline is actively being changed.
This resulted in an oops reported on lkml, see:

	http://marc.theaimsgroup.com/?l=linux-kernel&m=111342171410005&w=2

A 'hacky' approach was previously implmemented which served to eliminate the
poll vs.  line discipline changing race.  However, this patch takes a more
general approach to the issue.  The patch only adds locking on a less often
used path, the line-discipline changing path, as opposed to locking the
ptmx/pty pair on read/write/poll paths.

The patch below, takes both ldisc locks in either order b/c the locks are both
taken under the same spinlock().  I thought about locking the ptmx/pty
separately, such as master always first but that introduces a 3 way deadlock.
For example, process 1 does a blocking read on the slave side.  Then, process
2 does an ldisc change on the slave side, which acquires the master ldisc lock
but not the slave's.  Finally, process 3 does a write which blocks on the
process 2's ldisc reference.

This patch does introduce some changes in semantics.  For example, a line
discipline change on side 'a' of a ptmx/pty pair, will now wait for a
read/write to complete on the other side, or side 'b'.  The current behavior
is to simply wait for any read/writes on only side 'a', not both sides 'a' and
'b'.  I think this behavior makes sense, but I wanted to point it out.

I've tested the patch with a bunch of read/write/poll while changing the line
discipline out from underneath.

This patch obviates the need for the above "hide the problem" patch.

Subject: [PATCH] files: break up files struct

In order for the RCU to work, the file table array, sets and their sizes must
be updated atomically.  Instead of ensuring this through too many memory
barriers, we put the arrays and their sizes in a separate structure.  This
patch takes the first step of putting the file table elements in a separate
structure fdtable that is embedded withing files_struct.  It also changes all
the users to refer to the file table using files_fdtable() macro.  Subsequent
applciation of RCU becomes easier after this.

Subject: [PATCH] files: lock-free fd look-up

With the use of RCU in files structure, the look-up of files using fds can now
be lock-free.  The lookup is protected by rcu_read_lock()/rcu_read_unlock().
This patch changes the readers to use lock-free lookup.

Subject: [PATCH] console: Fix buffer copy on vc resize

On a vc resize, the contents of the old screen buffer are transferred to the
new screenbuffer.  If the new screenbuffer is smaller than the old one, only
the contents from the bottom are copied to new.  If the contents of the old
buffer are located at the top, then the contents will not be copied to the new
buffer resulting in a blank screen.

This bug will happen only if the vc in question is not in the foreground.
Doing an fbset -a or con2fbmap will trigger this bug.

To fix this problem, base the start of the copy from the location of the
current cursor.  If the cursor is near the top of the buffer, copy the
contents at the top, and if the cursor is near the bottom of the buffer, then
copy the contents at the bottom.  In the unlikely case where the new row size
is greater than 2x smaller than the old one, and the cursor is in the middle,
copy 1/2 screenful from the top and bottom of the cursor position.

I've noticed that the patch from Ben Dooks (commit
af4bb822bc65efb087cd36b83789f22161a6515b on your git tree) is
introducing a warning. It's using 'u32 state' instead of 'pm_message_t
state'. I've attached a one liner to fix it.

Subject: [PATCH] vfree and kfree cleanup in drivers/

This patch does a full cleanup of 'NULL checks before vfree', and a partial
cleanup of calls to kfree for all of drivers/ - the kfree bit is partial in
that I only did the files that also had vfree calls in them.  The patch
also gets rid of some redundant (void *) casts of pointers being passed to
[vk]free, and a some tiny whitespace corrections also crept in.

Subject: [WATCHDOG] i6300esb.patch

I wrote earlier to the list[1] asking for a driver for the watchdog
included in the 6300ESB chipset.  I got a 2.4 driver via private email
from Ross Biro which I've changed into what I hope resembles a 2.6
driver (which was done by looking a lot at the watchdog drivers
already in the 2.6 tree).

I've attached the result, and I'm hoping to get some feedback on the
coding as a first step.  I can't actually test it on the hardware
right now as I won't have physical access until April. So my own tests
have been limited to "compiles-without-warnings" and
"can-be-insmodded-in-other-machine-without-oops".

Subject: [WATCHDOG] removes pci_find_device from i6300esb.c

This patch changes pci_find_device to pci_get_device
(encapsulated in for_each_pci_dev) in i6300esb watchdog
card with appropriate adding pci_dev_put.

Generated in 2.6.13-rc5-mm1 kernel version.

Subject: [WATCHDOG] i6300esb.c-WDT_ENABLE-bug

This patch sets the WDT_ENABLE bit of the Lock Register to enable the
watchdog and WDT_LOCK bit only if nowayout is set. The old code always
sets the WDT_LOCK bit of watchdog timer for Intel 6300ESB chipset. So, we
end up locking the watchdog instead of enabling it.

In i6300esb.c watchdog card driver were 2 bugs (misused pc_match_device and
pci_dev_put wasn't called in one error case) and one little cleanup was
done (long line was converted to a shorter one with using built-in macro).

the attached patch moves the content of drivers/char/watchdog/i6300.h
into drivers/char/watchdog/i6300.c, since it is the only file using the
defines there is no real reason to have a separate header.

Also cleaned up the comments a bit and added myself to the copyright
holders.

 driver-for-ibm-automatic-server-restart-watchdog-fix2.patch

The device/watchdog has a fixed timeout/heartbeat.
So we don't support the WDIOC_SETTIMEOUT ioctl call
and we also may not set the WDIOF_SETTIMEOUT flag.

+ *
+ * Watchdog Timer Configuration
+ *
+ * The function of the watchdog timer is to reset the system automatically
+ * and is defined at I/O port 0120H and 0121H.  To enable the watchdog timer
+ * and allow the system to reset, write appropriate values from the table
+ * below to I/O port 0120H and 0121H.  To disable the timer, write a zero
+ * value to I/O port 0121H for the system to stop the watchdog function.
+ *
+ * The following describes how the timer should be programmed (according to
+ * the vendor documentation)
+ *
+ * Enabling Watchdog:
+ * MOV AX,000AH (enable, phase I)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000BH (enable, phase II)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000nH (set multiplier n, from 1-4)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000mH (set base timer m, from 0-F)
+ * MOV DX,0121H
+ * OUT DX,AX
+ *
+ * Reset timer:
+ * MOV AX,000mH (same as set base timer, above)
+ * MOV DX,0121H
+ * OUT DX,AX
+ *
+ * Disabling Watchdog:
+ * MOV AX,0000H (a zero value)
+ * MOV DX,0120H
+ * OUT DX,AX
+ *
+ * Watchdog timeout configuration values:
+ *		N
+ *	M |	1	2	3	4
+ *	--|----------------------------------
+ *	0 |	0.5s	5s	50s	100s
+ *	1 |	1s	10s	100s	200s

Subject: [WATCHDOG] w83977f-watchdog-driver.patch

In a project for my company I've needed to use the watchdog device in a
PCM-5335 SBC from AAEON.  The watchdog timer is from a Winbond's SuperIO
chip, the W83977F.

I've made this driver based on two others already on the kernel tree,
the w83877f_wdt and the wdt977.

Subject: [PATCH] hvc_console: start kernel thread before registering tty

Its possible that we can write to the hvc_console tty as soon it is
registered.  Recently this started happening due to (what looks like) a
change to the hotplug code.

Unfortunately at this stage we have not started the khvcd kernel thread and
oops.  The solution is to start the kernel thread before registering the
tty.

Subject: [PATCH] epca iomem annotations + several missing readw()

[originally sent to Alan, he had no problems with it]

 - iomem pointers marked as such
 - several direct dereferencings of such pointers replaced with read[bw]().

Subject: [PATCH] Fix mmap() of /dev/hpet

The address passed to io_remap_pfn_range() in hpet_mmap() does not need to
be converted using __pa(): it is already a physical address.  This bug was
found and the patch suggested by Clay Harris.

I introduced this particular bug when making io_remap_pfn_range changes a
few months ago.  In fact mmap()ing /dev/hpet has *never* previously worked:
before my changes __pa() was being executed on an ioremap()ed virtual
address, which is also invalid.
