[PATCH] IPMI: Fix oops on ipmi_msghandler removal for non ipmi systems
When the ipmi_si module is loaded on a system without any ipmi device, it
fails with nodev. It would be fine if all resources were freed. A call to
device_unregister() is missing, resulting to a oops when you remove the
ipmi_msghandler.

[POWERPC] Fix MMIO ops to provide expected barrier behaviour
This changes the writeX family of functions to have a sync instruction
before the MMIO store rather than after, because the generally expected
behaviour is that the device receiving the MMIO store can be guaranteed
to see the effects of any preceding writes to normal memory.
To preserve ordering between writeX and readX, and to preserve ordering
between preceding stores and the readX, the readX family of functions
have had an sync added before the load.
Although writeX followed by spin_unlock is not officially guaranteed
to keep the writeX inside the spin-locked region unless an mmiowb()
is used, there are currently drivers that depend on the previous
behaviour on powerpc, which was that the mmiowb wasn't actually required.
Therefore we have a per-cpu flag that is set by writeX, cleared by
__raw_spin_lock and mmiowb, and tested by __raw_spin_unlock. If it is
set, __raw_spin_unlock does a sync and clears it.
This changes both 32-bit and 64-bit readX/writeX. 32-bit already has a
sync in __raw_spin_unlock (since lwsync doesn't exist on 32-bit), and thus
doesn't need the per-cpu flag.

architectures that needed it (ia64, sparc and sparc64).
Architectures that don't have any special requirements can just ignore

Both MMC and SD specifications specify (although a bit unclearly in
the MMC case) that a sector size of 512 bytes must always be
supported by the card.
Cards can report larger "native" size than this, and cards >= 2 GB
even must do so. Most other readers use 512 bytes even for these
cards. We should do the same to be compatible.

[ARM] 3751/1: i.MX/MX1 SD/MMC use 512 bytes request for SCR read
Patch from Pavel Pisa
This is another approach to SDHC deficiency workaround.
It seems, that previous solution based on 16 bytes (FIFO length size)
read is still timing sensitive on genirq and fully preemptive kernels.
The new solution is backuped by M9328 UM statement, that only 512 byte
block are working properly and by 2.4.26 FreeScale's SDHC code.
Jay Monkman reports significant improvement on code based
on this driver after applying this change on MX21 as well.

[XFS] Fix xfs_splice_write() so appended data gets to disk.
xfs_splice_write() failed to update the on disk inode size when extending
the so when the file was closed the range extended by splice was truncated
off. Hence any region of a file written to by splice would end up as a
hole full of zeros.
[XFS] Fix ABBA deadlock between i_mutex and iolock. Avoid calling
__blockdev_direct_IO for the DIO_OWN_LOCKING case for direct I/O reads
since it drops and reacquires the i_mutex while holding the iolock and
this violates the locking order.

[XFS] Prevent free space oversubscription and xfssyncd looping.
The fix for recent ENOSPC deadlocks introduced certain limitations on
allocations. The fix could cause xfssyncd to loop endlessly if we did not
leave some space free for the allocator to work correctly. Basically, we
needed to ensure that we had at least 4 blocks free for an AG free list
and a block for the inode bmap btree at all times.
However, this did not take into account the fact that each AG has a free
list that needs 4 blocks. Hence any filesystem with more than one AG could
cause oversubscription of free space and make xfssyncd spin forever trying
to allocate space needed for AG freelists that was not available in the
AG.
The following patch reserves space for the free lists in all AGs plus the
inode bmap btree which prevents oversubscription. It also prevents those
blocks from being reported as free space (as they can never be used) and
makes the SMP in-core superblock accounting code and the reserved block
ioctl respect this requirement.
