[XFS] xfssyncd is responsible for flushing inode or device's data by
extracting the work from its queue. In addition, this processing also
decrement the inode's i_count. If there are any remaining works in queue
before this process terminates, we have unbalanced increment and decrement
of i_count. Thus it can cause assertion failure of vn_count. The fix
allows xyssyncd to process any remaining work before it is shutdown.

[XFS] Initial pass at going directly-to-bio on the buffered IO path. This
allows us to submit much larger I/Os instead of sending down lots of small
buffer_heads. To do this we need to have a rather complicated I/O
submission and completion tracking infrastructure. Part of the latter has
been merged already a long time ago for direct I/O support. Part of the
problem is that we need to track sub-pagesize regions and for that we
still need buffer_heads for the time beeing. Long-term I hope we can move
to better data strucutures and/or maybe move this to fs/mpage.c instead of
having it in XFS. Original patch from Nathan Scott with various updates

We're starting a number of big applications (memory footprint app.
1MByte) on our Arcturus uC5272. Therefore memory fragmentation is a
real pain for us. We've switched to uClinux-2.4.27-uc1 and found that
page_alloc2 fragments the memory heavily.
Digging into it we found a bug in the find_next_zero_bit function in the
m68knommu/bitops.h file. if the size isn't a multiple of 32 than the
upper bits of the last word to be searched should be masked. But the
functions masks the lower bits of the last word because it uses a right
shift instead of a left shift operator.

[PATCH] m68knommu: fix a5 reg corruption in signal handlers
This is a patch adapted from a posting by Andrea Tarani which was
pointed out to me by Bernardo Innocenti. Thanks to both of them for
their help and patience.
The original posting is here:
http://mailman.uclinux.org/pipermail/uclinux-dev/2005-July/033543.html
The problem first manifest itself as busybox ping terminating with an
"Illegal instruction". I reduced this to a test case and found that
variable size arrays allocated on the stack could lead to stacks not
aligned on 32 bit boundaries. For the Coldfire this proved fatal.
Having been pointed out this patch by Bernardo, I applied it and it
fixed the first test case. I then went back to busybox's ping. This
still failed with "Illegal instruction", but in a different way. Before
it depended on the size allocated for the ping buffer, now it happened
every time. I also found it depended on optimisation level (gcc-3.4.0)
-Os was okay but not -O2.
After a lot of looking, it turned out that register a5 was being
corrupted by the signal handler (after applying the patch). I re-worked
the patch a bit to save/restore a5 and now all seems well.

[PATCH] Work around ppc64 compiler bug
In the process of optimising our per cpu data code, I found a ppc64
compiler bug that has been around forever. Basically the current
RELOC_HIDE can end up trashing r30. Details of the bug can be found at
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25572
This bug is present in all compilers before 4.1. It is masked by the
fact that our current per cpu data code is inefficient and causes
other loads that end up marking r30 as used.
A workaround identified by Alan Modra is to use the =r asm constraint
instead of =g.
