2011-04-14ARM: 6879/1: fix personality test wrt usage of domain handlersNicolas Pitre
There are optional bits that may complement a personality ID. It is therefore wrong to simply test against the absolute current->personality value to determine the effective personality. The PER_LINUX_32BIT is itself just PER_LINUX with one of those optional bits set. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-04-14ARM: 6878/1: fix personality flag propagation across an execNicolas Pitre
Our SET_PERSONALITY() implementation was overwriting all existing personality flags, including ADDR_NO_RANDOMIZE, making them unavailable to processes being exec'd after a call to personality() in user space. This prevents the gdb test suite from running successfully. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-04-11pci: fix PCI bus allocation alignment handlingLinus Torvalds
In commit 13583b16592a ("PCI: refactor io size calculation code") Ram had a thinko in the refactorization of the code: the end result used the variable 'align' for the bus alignment, but the original code used 'min_align'. Since then, another use of that 'align' variable got introduced by commit c8adf9a3e873 ("PCI: pre-allocate additional resources to devices only after successful allocation of essential resources.") Fix both of those uses to use 'min_align' as they should.

2011-04-10ext4: sync the directory inode in ext4_sync_parent()Curt Wohlgemuth
ext4 has taken the stance that, in the absence of a journal, when an fsync/fdatasync of an inode is done, the parent directory should be sync'ed if this inode entry is new. ext4_sync_parent(), which implements this, does indeed sync the dirent pages for parent directories, but it does not sync the directory *inode*. This patch fixes this. Also now return error status from ext4_sync_parent(). I tested this using a power fail test, which panics a machine running a file server getting requests from a client. Without this patch, on about every other test run, the server is missing many, many files that had been synced. With this patch, on > 6 runs, I see zero files being lost.

2011-04-08xfs: use proper interfaces for on-stack pluggingChristoph Hellwig
Add proper blk_start_plug/blk_finish_plug pairs for the two places where we issue buffer I/O, and remove the blk_flush_plug in xfs_buf_lock and xfs_buf_iowait, given that context switches already flush the per-process plugging lists.

2011-04-08xfs: fix xfs_debug warningsChristoph Hellwig
For a CONFIG_XFS_DEBUG=n build gcc complains about statements with no effect in xfs_debug: fs/xfs/quota/xfs_qm_syscalls.c: In function 'xfs_qm_scall_trunc_qfiles': fs/xfs/quota/xfs_qm_syscalls.c:291:3: warning: statement with no effect The reason for that is that the various new xfs message functions have a return value which is never used, and in case of the non-debug build xfs_debug the macro evaluates to a plain 0 which produces the above warnings. This can be fixed by turning xfs_debug into an inline function instead of a macro, but in addition to that I've also changed all the message helpers to return void as we never use their return values.

When bringing the port up, performing a SENSE_PORT command To try and check to which physical link type (IB or Ethernet) the physical port is connected. In case there is no valid link partner, the port will come up as its supported default. Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-04-08xfs: convert log tail checking to a warningDave Chinner
On the Power platform, the log tail debug checks fire excessively causing the system to panic early in testing. The debug checks are known to be racy, though on x86_64 there is no evidence that they trigger at all. We want to keep the checks active on debug systems to alert us to problems with log space accounting, but we need to reduce the impact of a racy check on testing on the Power platform. As a result, convert the ASSERT conditions to warnings, and allow them to fire only once per filesystem mount. This will prevent false positives from interfering with testing, whilst still providing us with the indication that they may be a problem with log space accounting should that occur.

2011-04-08xfs: catch bad block numbers freeing extents.Dave Chinner
A fuzzed filesystem crashed a kernel when freeing an extent with a block number beyond the end of the filesystem. Convert all the debug asserts in xfs_free_extent() to active checks so that we catch bad extents and return that the filesytsem is corrupted rather than crashing.
