Use del_timer_sync() instead of del_timer() to make sure the timer won't
be running when we return from parport_wait_event(), because this would
crash due to destruction of timer_list.This is untested and just based on a code review. Just think about the
following sequence of events:- add_timer()
- down_interruptible() is interrupted by a signal.
- we enter the timer callback handler on another CPU.
- del_timer(), but the timer callback is still running.
- eturn from parport_wait_even, which destroys the automatic variable
"timer" while the callback is running on another CPU.[akpm@linux-foundation.org: coding-style fixes]

Since all sanity checks rely on the validity of s_start which gets only
checked to be smaller than s_end, we should also check if s_end is sane.
Now we also try to retrieve the last block of the filesystem, which is
computed by s_end. If this fails, something is bogus.Signed-off-by: Eric Sesterhenn

bfs_fill_super() already touches all inodes, so we can easily add some
cheap sanity checks and check if the inode start and end blocks are
smaller than the maximum number of blocks, the inode start block lies
behind the end block or the file end offset is behind the end of the
filesystem. Also check if the start of data offset in the super block
fits the filesystem.The added sanity checks catch softlockup issues early when we try to
sb_bread() lots of blocks in a loop in bfs_readdir() and bfs_find_entry().
In addition an oom issue in bfs_fill_super() is prevented by this when
s_start is corrupted, which influences imap_len and we try to allocate a
huge info->si_imap.Signed-off-by: Eric Sesterhenn

Prevent passing an order to bitmap_find_free_region() that is larger than
the actual bitmap can represent.These requests can come from device drivers that have no idea how big the
dma region is and need to rely on dma_alloc_from_coherent() to sort it out
for them.Reported-by: Guennadi Liakhovetski

If bitmap_find_free_region() fails and DMA_MEMORY_EXCLUSIVE is not set,
the function will fail to write anything to *ret and will return 1. This will cause dma_alloc_coherent() to return an uninitialised value,
crashing the kernel, perhaps via DMA to a random address.Fix that by changing it to return zero in this case, so the caller will
proceed to allocate the memory from the generic memory allocator.Cc: Tetsuo Handa

All other compatibles that are uniquely identifying the processor use a
prefix of the form fsl,mpc85...'. We add support for it so we can
deprecate the older 'fsl,85...' that was improperly used here.Additionally added mpc8536 & mpc8560 to the compatible lists.

As a non-atomic value, it's only safe to look at entropy_count when the
pool lock is held, so we move the BUG_ON inside the lock for correctness.Also remove the spurious comment. It's ok for entropy_count to
temporarily exceed POOLBITS so long as it's left in a consistent state
when the lock is released.This is a more correct, simple, and idiomatic fix for the bug in
8b76f46a2db. I've left the reorderings introduced by that patch in place
as they're harmless, even though they don't properly deal with potential
atomicity issues.Signed-off-by: Matt Mackall

Make firmware/dsp56k/bootstrap.asm buildable on a56, the free Motorola
DSP56001 assembler (http://www.zdomain.com/a56.html).Summary of changes:
- Remove '' candy (they specify explicit addressing modes,
which a56 don't grok, but uses implicitly anyway).- Replace 'move' with 'movem' when accessing program memory.
- Rename a few labels to avoid duplicates (which a56 can't handle).

Introduce a new kernel parameter `coredump_filter'. Setting a value to
this parameter causes the default bitmask of coredump_filter to be
changed.It is useful for users to change coredump_filter settings for the whole
system at boot time. Without this parameter, users have to change
coredump_filter settings for each /proc// in an initializing script.Signed-off-by: Hidehiro Kawai

POSIX requires the si_pid to be the process id of the sender, so ->si_pid
should really be set to 'tgid'. This change does have following changes
in behavior:- When sending pdeath_signal on re-parent to a sub-thread, ->si_pid
cannot be used to identify the thread that did the re-parent since
it will now show the tgid instead of thread id.- A multi-threaded application that expects to find the specific
thread that encountered a SIGPIPE using the ->si_pid will now
break.Signed-off-by: Sukadev Bhattiprolu

The code to draw penguin logos always uses some properties of the main logo.
This is incorrect if additional logos (CONFIG_FB_LOGO_EXTRA=y) have different
types than the main logo, which causes corrupted logo images.http://bugzilla.kernel.org/show_bug.cgi?id=12181
Hence skip additional logos that are not compatible with the main logo.
Technically, it's possible to draw multiple logos of different types on
truecolor displays, but this would complicate the (already quite
complicated) logo drawing code even more.This patch fixes a problem with Debian's linux-image-2.6.26-1-powerpc64
