Fix up trivial conflict in arch/arm/kernel/signal.c.

It was due to the TIF_NOTIFY_RESUME addition in commit d0420c83 ("KEYS:
Extend TIF_NOTIFY_RESUME to (almost) all architectures") and follow-ups.

My 353d5c30 "mm: fix hugetlb bug due to
user_shm_unlock call" broke the CONFIG_SYSVIPC !CONFIG_MMU build of both
2.6.31 and 2.6.30.6: "undefined reference to `user_shm_unlock'".

gcc didn't understand my comment! so couldn't figure out to optimize
away user_shm_unlock() from the error path in the hugetlb-less case, as
it does elsewhere.  Help it to do so, in a language it understands.

When we close a file, we remove preallocated blocks from it. But this
truncation was not protected by i_mutex and thus it could have raced with a
write through a different fd and cause crashes or even filesystem corruption.
Signed-off-by: NJan Kara <jack@suse.cz>

So far we preallocated blocks also for directories but that brings a
problem, when to get rid of preallocated blocks we don't need. So far
we removed them in udf_clear_inode() which has a disadvantage that
1) blocks are unavailable long after writing to a directory finished
   and thus one can get out of space unnecessarily early
2) releasing blocks from udf_clear_inode is problematic because VFS
   does not expect us to redirty inode there and it also slows down
   memory reclaim.

So preallocate blocks only for regular files where we can drop preallocation
in udf_release_file.

This is the MCE error code from the MCi_STATUS banks, bits [15:0] which

This is in preparation of adding AMD-specific MCE decoding functionality
to the EDAC core. The error decoding macros originate from the AMD64
EDAC driver albeit in a simplified and cleaned up version here.

While at it, add macros to generate the error description strings and
use them in the error type decoders directly which removes a bunch of
code and makes the decoding functions much more readable. Also, fix
strings and shorten macro names.

Remove superfluous htlink_msgs.

Currenly vfs_fsync(_range) first calls filemap_fdatawrite to write out
the data, the calls into ->fsync to write out the metadata and then finally
calls filemap_fdatawait to wait for the data I/O to complete.  What sounds
like a clever micro-optimization actually is nast trap for many filesystems.

For many modern filesystems i_size or other inode information is only
updated on I/O completion and we need to wait for I/O to finish before
we can write out the metadata.  For old fashionen filesystems that
instanciate blocks during the actual write and also update the metadata
at that point it opens up a large window were we could expose uninitialized
blocks after a crash.  While a few filesystems that need it already wait
for the I/O to finish inside their ->fsync methods it is rather suboptimal
as it is done under the i_mutex and also always for the whole file instead
of just a part as we could do for O_SYNC handling.

Here is a small audit of all fsync instances in the tree:

 - spufs_mfc_fsync:
 - ps3flash_fsync:
 - vol_cdev_fsync:
 - printer_fsync:
 - fb_deferred_io_fsync:
 - bad_file_fsync:
 - simple_sync_file:

	don't care - filesystems/drivers do't use the page cache or are
	purely in-memory.

 - simple_fsync:
 - file_fsync:
 - affs_file_fsync:
 - fat_file_fsync:
 - jfs_fsync:
 - ubifs_fsync:
 - reiserfs_dir_fsync:
 - reiserfs_sync_file:

	never touch pagecache themselves.  We need to wait before if we do
	not want to expose stale data after an allocation.

 - afs_fsync:
 - fuse_fsync_common:

	do the waiting writeback itself in awkward ways, would benefit from
	proper semantics

 - block_fsync:

	Does a filemap_write_and_wait on the block device inode.  Because we
	now have f_mapping that is the same inode we call it on in vfs_fsync.
	So just removing it and letting the VFS do the work in one go would
	be an improvement.

 - btrfs_sync_file:
 - cifs_fsync:
 - xfs_file_fsync:

	need the wait first and currently do it themselves. would benefit from
	doing it outside i_mutex.

 - coda_fsync:
 - ecryptfs_fsync:
 - exofs_file_fsync:
 - shm_fsync:

	only passes the fsync through to the lower layer

 - ext3_sync_file:

	doesn't seem to care, comments are confusing.

 - ext4_sync_file:

	would need the wait to work correctly for delalloc mode with late
	i_size updates.  Otherwise the ext3 comment applies.

	currently implemens it's own writeback and wait in an odd way,
	could benefit from doing it properly.

 - gfs2_fsync:

	not needed for journaled data mode, but probably harmless there.
	Currently writes back data asynchronously itself.  Needs some
	major audit.

 - hostfs_fsync:

	just calls fsync/datasync on the host FD.  Without the wait before
	data might not even be inflight yet if we're unlucky.

 - hpfs_file_fsync:
 - ncp_fsync:

	no-ops.  Dangerous before and after.

 - jffs2_fsync:

	just calls jffs2_flush_wbuf_gc, not sure how this relates to data.

 - nfs_fsync_dir:

	just increments stats, claims all directory operations are synchronous

 - nfs_file_fsync:

	only writes out data???  Looks very odd.

 - nilfs_sync_file:

	looks like it expects all data done, but not sure from the code

 - ntfs_dir_fsync:
 - ntfs_file_fsync:

	appear to do their own data writeback.  Very convoluted code.

 - ocfs2_sync_file:

	does it's own data writeback, but no wait.  probably needs the wait.

 - smb_fsync:

	according to a comment expects all pages written already, probably needs
	the wait before.

This patch only changes vfs_fsync_range, removal of the wait in the methods
that have it is left to the filesystem maintainers.  Note that most
filesystems really do need an audit for their fsync methods given the
gems found in this very brief audit.
