The isl29003 does not interpret the return value of
i2c_smbus_write_byte_data() correctly and hence causes an error on system
resume.

The software fillrect routines do not work properly when the number of
pixels per machine word is not an integer. To see that, run the following
command on a fbdev console with a 24bpp video mode, using a
non-accelerated driver such as (u)vesafb:
reset ; echo -e '\e[41mtest\e[K'
The expected result is 'test' displayed on a line with red background.
Instead of that, 'test' has a red background, but the rest of the line
(rendered using fillrect()) contains a distored colorful pattern.
This patch fixes the problem by correctly computing rotation shifts. It
has been tested in a 24bpp mode on 32- and 64-bit little-endian machines.

When /proc/sys/vm/oom_kill_allocating_task is set for large systems that
want to avoid the lengthy tasklist scan, it's possible to livelock if
current is ineligible for oom kill. This normally happens when it is set
to OOM_DISABLE, but is also possible if any threads are sharing the same
->mm with a different tgid.
So change __out_of_memory() to fall back to the full task-list scan if it
was unable to kill `current'.

When building with gcc 3.2 I get thousands of warnings such as

due to passing a NULL format string to warn_slowpath() in

Split this case out into a separate call. This also shrinks the kernel

There is what we believe to be a false positive reported by lockdep.
inotify_inode_queue_event() => take inotify_mutex => kernel_event() =>
kmalloc() => SLOB => alloc_pages_node() => page reclaim => slab reclaim =>
dcache reclaim => inotify_inode_is_dead => take inotify_mutex => deadlock
The plan is to fix this via lockdep annotation, but that is proving to be
quite involved.
The patch flips the allocation over to GFP_NFS to shut the warning up, for
the 2.6.30 release.
Hopefully we will fix this for real in 2.6.31. I'll queue a patch in -mm
to switch it back to GFP_KERNEL so we don't forget.

madvise(MADV_WILLNEED) forces page cache readahead on a range of memory
backed by a file. The assumption is made that the page required is
order-0 and "normal" page cache.
On hugetlbfs, this assumption is not true and order-0 pages are
allocated and inserted into the hugetlbfs page cache. This leaks
hugetlbfs page reservations and can cause BUGs to trigger related to
corrupted page tables.
This patch causes MADV_WILLNEED to be ignored for hugetlbfs-backed
regions.
