2008-12-10relayfs: fix infinite loop with splice()Tom Zanussi
Running kmemtraced, which uses splice() on relayfs, causes a hard lock on x86-64 SMP. As described by Tom Zanussi: It looks like you hit the same problem as described here: commit 8191ecd1d14c6914c660dfa007154860a7908857 splice: fix infinite loop in generic_file_splice_read() relay uses the same loop but it never got noticed or fixed.

Currently audit=0 on the kernel command line does absolutely nothing. Audit always loads and always uses its resources such as creating the kernel netlink socket.

Since applying the fix suggested by the errata (disabling MSI), we've had issues with interrupts being stuck on despite IIR being 0 on GM965 hardware. Most reporters of the issue have confirmed that turning MSI back on fixes things, and given the difficulties experienced in getting reliable MSI working on Linux, it's believable that the errata was about software issues and not actual hardware issues.

2008-12-08EXPORTFS: handle NULL returns from fh_to_dentry()/fh_to_parent()J. Bruce Fields
While 440037287c5 "[PATCH] switch all filesystems over to d_obtain_alias" removed some cases where fh_to_dentry() and fh_to_parent() could return NULL, there are still a few NULL returns left in individual filesystems. Thus it was a mistake for that commit to remove the handling of NULL returns in the callers. Revert those parts of 440037287c5 which removed the NULL handling. (We could, alternatively, modify all implementations to return -ESTALE instead of NULL, but that proves to require fixing a number of filesystems, and in some cases it's arguably more natural to return NULL.)

2008-12-07[ARM] Fix alignment fault handling for ARMv6 and later CPUsRussell King
On ARMv6 and later CPUs, it is possible for userspace processes to get stuck on a misaligned load or store due to the "ignore fault" setting; unlike previous CPUs, retrying the instruction without the 'A' bit set does not always cause the load to succeed. We have no real option but to default to fixing up alignment faults on these CPUs, and having the CPU fix up those misaligned accesses which it can.

2008-12-06[ARM] 5340/1: fix stack placement after noexecstack changesLennert Buytenhek
Commit 8ec53663d2698076468b3e1edc4e1b418bd54de3 ("[ARM] Improve non-executable support") added support for detecting non-executable stack binaries. One of the things it does is to make READ_IMPLIES_EXEC be set in ->personality if we are running on a CPU that doesn't support the XN ("Execute Never") page table bit or if we are running a binary that needs an executable stack. This exposed a latent bug in ARM's asm/processor.h due to which we'll end up placing the stack at a very low address, where it will bump into the heap on any application that uses significant amount of stack or heap or both, causing many interesting crashes. Fix this by testing the ADDR_LIMIT_32BIT bit in ->personality instead of testing for equality against PER_LINUX_32BIT.

2008-12-05Enforce a minimum SG_IO timeoutLinus Torvalds
There's no point in having too short SG_IO timeouts, since if the command does end up timing out, we'll end up through the reset sequence that is several seconds long in order to abort the command that timed out. As a result, shorter timeouts than a few seconds simply do not make sense, as the recovery would be longer than the timeout itself. Add a BLK_MIN_SG_TIMEOUT to match the existign BLK_DEFAULT_SG_TIMEOUT.

Commit aaad077638be1a25871bcae5e43952d6b63abfca (that failed "Fix ACPI battery regression") got the voltage conversion confused, and fixed the problem with Rafael's battery monitor apparently just by mistake.
