* introduce HAVE_EFFICIENT_UNALIGNED_ACCESS Kconfig symbolJohannes Berg2008-07-25
| | | | | | | | | | | | | | | | | | | In many cases, especially in networking, it can be beneficial to know at compile time whether the architecture can do unaligned accesses efficiently. This patch introduces a new Kconfig symbol HAVE_EFFICIENT_UNALIGNED_ACCESS for that purpose and adds it to the powerpc and x86 architectures. Also add some documentation about alignment and networking, and especially one intended use of this symbol.

* lists: remove a redundant conditional definition of list_add()Robert P. J. Day2008-07-25
| | | | | | | | | | | | Remove the conditional surrounding the definition of list_add() from list.h since, if you define CONFIG_DEBUG_LIST, the definition you will subsequently pick up from lib/list_debug.c will be absolutely identical, at which point you can remove that redundant definition from list_debug.c as well.

* lib: allow memparse() to accept a NULL and ignorable second parmRobert P. J. Day2008-07-25
| | | | | | | | | | | | | | | | | | | Extend memparse() to allow the caller to use a NULL second parameter, which would represent no interest in returning the address of the end of the parsed string. In numerous cases, callers invoke memparse() to parse a possibly-suffixed string (such as "64K" or "2G" or whatever) and define a character pointer to accept the end pointer being returned by memparse() even though they have no interest in it and promptly throw it away. This (backward-compatible) enhancement allows callers to use NULL in the cases where they just don't care about getting back that end pointer.

* find dynamic stack allocations in checkstack.plEric Sandeen2008-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, checkstack.pl only looks for fixed subtractions from the stack pointer. However, things like this: void function(int size) { char stackbuster[size << 2]; ... are certainly worth pointing out, I think. This could perhaps be done more cleanly, and the following patch only adds "dynamic" REs for x86 and x86_64, but it works: 0x00b0 crypto_cbc_decrypt_inplace [cbc]: Dynamic (%rax) 0x00ad crypto_pcbc_decrypt_inplace [pcbc]: Dynamic (%rax) 0x02f6 crypto_pcbc_encrypt_inplace [pcbc]: Dynamic (%rax) 0x036c _crypto_xcbc_digest_setkey [xcbc]: Dynamic (%rax) ...

This allows virtio_console to use hvc_console without having a linker reference to request_irq/free_irq. In addition, together with patch 2/3 it improves the performance for virtio console input. (an earlier version of this patch was tested by Yajin on lguest) The irq specific code is moved to hvc_irq.c and selected by the drivers that use irqs (System p, System i, XEN). I replaced "int irq" with the opaque "int data". The request_irq and free_irq calls are replaced with notifier_add and notifier_del. I have also changed the code a bit to call the notifier_add and notifier_del inside the spinlock area as the callbacks are found via hp->ops. Changes since last version: o remove ifdef o reintroduce "irq_requested" as "notified" o cleanups, sparse.. I did not move the timer based polling into a separate polling scheme. I played with several variants, but it seems we need to sleep/schedule in a thread even for irq based consoles, as there are throttleing and buffer size constraints. I also kept hvc_struct defined in hvc_console.h so that hvc_irq.c can access the irq_requested element. Feedback is appreciated. virtio_console is currently the only available console for kvm on s390. I plan to push this change as soon as all affected parties agree on it.

| | | | | | | | | | | | | | | | | | | | | | | | Currently virtio_blk assumes a 512 byte hard sector size.

This seemed like a good idea at the time: if we fill the transmit ring, we should tell the host immediately. Unfortunately this logic also applies to the receiving ring, which is refilled constantly. We should introduce real notification thesholds to replace this logic. Meanwhile, removing the logic altogether breaks the heuristics which KVM uses, so we use a hack: only notify if there are outgoing parts of the new buffer.

Poor wee skb :) How about the incremental patch below? Cheers, Mark. Subject: [PATCH] virtio_net: Delay dropping tx skbs Currently we drop the skb in start_xmit() if we have a queued buffer and fail to transmit it.

|/ | | | | | | | | | | | | | | | | | | | Suresh Siddha wants to fix a possible FPU leakage in error conditions, but the fact that save/restore_i387() are inlines in a header file makes that harder to do than necessary. So start off with an obvious cleanup. This just moves the x86-64 version of save/restore_i387() out of the header file, and moves it to the only file that it is actually used in: arch/x86/kernel/signal_64.c. So exposing it in a header file was wrong to begin with. [ Side note: I'd like to fix up some of the games we play with the 32-bit version of these functions too, but that's a separate matter. The 32-bit versions are shared - under different names at that! - by both the native x86-32 code and the x86-64 32-bit compatibility code ] Acked-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * ide: fix for EATA SCSI HBA in ATA emulating modeBartlomiej Zolnierkiewicz2008-07-24
| | | | | | | | | | | | | | | | | | | | | | | | IDE probing code used to skip devices attached to EATA SCSI HBA in ATA emulating mode but because of warm-plug support port I/O resources are no longer freed if no devices are detected on a port and the decision about the driver to use is left up to the user. Remove no longer valid EATA SCSI HBA quirk from do_identify(). Noticed-by: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

| * ide: enable local IRQs in all handlers for TASKFILE_NO_DATA data phaseBartlomiej Zolnierkiewicz2008-07-24
| | | | | | | | | | | | | | It is already done by task_no_data_intr() and there is no reason not to do it in other TASKFILE_NO_DATA data phase handlers. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

| * ide-cd: fix oops when using growisofsJens Axboe2008-07-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cdrom_read_capacity() will blindly return the capacity from the device without sanity-checking it. This later causes code in fs/buffer.c to oops. Fix this by checking that the device is telling us sensible things.

| * palm_bk3710: add UltraDMA/100 supportSergei Shtylyov2008-07-24
| | | | | | | | | | | | | | | | | | | | | | This controller supports UltraDMA up to mode 5 but it should be clocked with at least twice the data strobe frequency, so enable mode 5 for 100+ MHz IDECLK. While at it, start passing the correct device to clk_get() -- it worked anyway but WTF? :-/ Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
