2010-02-15ext4: Fix optional-arg mount optionsEric Sandeen
We have 2 mount options, "barrier" and "auto_da_alloc" which may or may not take a 1/0 argument. This causes the ext4 superblock mount code to subtract uninitialized pointers and pass the result to kmalloc, which results in very noisy failures. Per Ted's suggestion, initialize the args struct so that we know whether match_token() found an argument for the option, and skip match_int() if not. Also, return error (0) from parse_options if we thought we found an argument, but match_int() Fails. Reported-by: Michael S.

2010-02-04ext4: fix async i/o writes beyond 4GB to a sparse fileEric Sandeen
The "offset" member in ext4_io_end holds bytes, not blocks, so ext4_lblk_t is wrong - and too small (u32). This caused the async i/o writes to sparse files beyond 4GB to fail when they wrapped around to 0. Also fix up the type of arguments to ext4_convert_unwritten_extents(), it gets ssize_t from ext4_end_aio_dio_nolock() and ext4_ext_direct_IO().

2010-02-12GFS2: Fix bmap allocation corner-case bugSteven Whitehouse
This patch solves a corner case during allocation which occurs if both metadata (indirect) and data blocks are required but there is an obstacle in the filesystem (e.g. a resource group header or another allocated block) such that when the allocation is requested only enough blocks for the metadata are returned. By changing the exit condition of this loop, we ensure that a minimum of one data block will always be returned. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

2010-02-11fs/exec.c: restrict initial stack space expansion to rlimitMichael Neuling
When reserving stack space for a new process, make sure we're not attempting to expand the stack by more than rlimit allows. This fixes a bug caused by b6a2fea39318e43fee84fa7b0b90d68bed92d2ba ("mm: variable length argument support") and unmasked by fc63cf237078c86214abcb2ee9926d8ad289da9b ("exec: setup_arg_pages() fails to return errors"). This bug means that when limiting the stack to less the 20*PAGE_SIZE (eg. 80K on 4K pages or 'ulimit -s 79') all processes will be killed before they start. This is particularly bad with 64K pages, where a ulimit below 1280K will kill every process. To test, do: 'ulimit -s 15; ls' before and after the patch is applied. Before it's applied, 'ls' should be killed. After the patch is applied, 'ls' should no longer be killed. A stack limit of 15KB since it's small enough to trigger 20*PAGE_SIZE. Also 15KB not a multiple of PAGE_SIZE, which is a trickier case to handle correctly with this code. 4K pages should be fine to test with.

Commit b4846251727a38a7f248e41308c060995371dd05 ("edac: mpc85xx add mpc83xx support") accidentally broke how a chip select's first and last page addresses are calculated. The page addresses are being shifted too far right by PAGE_SHIFT. This results in errors such as: EDAC MPC85xx MC1: Err addr: 0x003075c0 EDAC MPC85xx MC1: PFN: 0x00000307 EDAC MPC85xx MC1: PFN out of range! EDAC MC1: INTERNAL ERROR: row out of range (4 >= 4) EDAC MC1: CE - no information available: INTERNAL ERROR The vaule of PAGE_SHIFT is already being taken into consideration during the calculation of the 'start' and 'end' variables, thus it is not necessary to account for it again when setting a chip select's first and last page address.

2010-02-11mmc_test: block addressed cardsJohan Kristell
This patch fixes a bug in the multiblock write tests where the written data is read back for verifying one block at a time. The tests in mmc_test assumes that all cards are byte addressable. This will cause the multi block write tests to fail, leading the user of the mmc_test driver thinking there is something wrong with the sdhci driver they are testing. The start address for the block is calculated as: blocknum * 512. For block addressable cards the blocknum alone should be used.

2010-02-11vgaarb: fix incorrect dereference of userspace pointer.Andy Getzendanner
This patch corrects a userspace pointer dereference in the VGA arbiter in 2.6.32.1. copy_from_user() is used at line 822 to copy the contents of buf into kbuf, but a call to strncmp() on line 964 uses buf rather than kbuf. This problem led to a GPF in strncmp() when X was started on my x86_32 systems. X triggered the behavior with a write of "target PCI:0000:01:00.0" to /dev/vga_arbiter. The patch has been tested against 2.6.32.1 and observed to correct the GPF observed when starting X or manually writing the string "target PCI:0000:01:00.0" to /dev/vga_arbiter.

Commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915: implement new pm ops for i915) introduced the problem that if s2disk hibernation is aborted, the system will crash, because i915_pm_freeze() does nothing, while it should at least reverse some operations carried out by i915_suspend(). Fix this issue by splitting the i915 suspend into a freeze part a suspend part, where the latter is not executed before creating a hibernation image, and the i915 resume into a "low-level" resume part and a thaw part, where the former is not executed after the image has been created.
