f4347553 removed the edac polling
mechanism in favor of using a notifier chain for conveying MCE
information to edac. However, the module removal path didn't test
whether the driver had setup the polling function workqueue at all and
the rmmod process was hanging in the kernel at try_to_del_timer_sync()
in the cancel_delayed_work() path, trying to cancel an uninitialized
work struct.

Fix that by adding a balancing check to the workqueue removal path.

System call entry functions sys_*() are never to be called from
general kernel code.  The fact that they aren't declared in header
files should have been a clue.  These functions also don't exist on
Alpha since it has sys_getxpid() instead.

In the commit f522886e a merge conflict
in the sdhci-s3c driver been fixed. However the fix used incorrect
spinlock operation - it caused a race with sdhci interrupt service. The
correct way to solve it is to use spin_lock_irqsave/irqrestore() calls.

We want interrupts disabled on all paths leading to RESTORE_ALL;
otherwise, we are risking an IRQ coming between the updates of
alpha_mv->hae_cache and *alpha_mv->hae_register and set_hae()
within the IRQ getting badly confused.

RESTORE_ALL used to play with disabling IRQ itself, but that got
removed back in 2002, without making sure we had them disabled
on all paths.  It's cheaper to make sure we have them disabled than
to revert to original variant...

Remove the detritus left from that commit back in 2002; we used to
need a reload of $0 and $1 since swpipl would change those, but
doing that had become pointless when we stopped doing swpipl in
there...

Thomas Pollet noticed that the remap_file_pages() system call in
fremap.c has a potential overflow in the first part of the if statement
below, which could cause it to process bogus input parameters.
Specifically the pgoff + size parameters could be wrap thereby
preventing the system call from failing when it should.

Add logic to prevent two I/O requests being merged if
only one of them is a discard.  Ditto secure discard.

Without this fix, it is possible for write requests
to transform into discard requests.  For example:

  Submit bio 1 to discard 8 sectors from sector n
  Submit bio 2 to write 8 sectors from sector n + 16
  Submit bio 3 to write 8 sectors from sector n + 8

Bio 1 becomes request 1.  Bio 2 becomes request 2.
Bio 3 is merged with request 2, and then subsequently
request 2 is merged with request 1 resulting in just
one I/O request which discards all 24 sectors.

  arch/tile: remove dead code from intvec_32.S

This "bpt_code" instruction was killed off in our development line a while
ago (the actual definition of bpt_code that is used is in kernel/traps.c)
but I didn't push it for 2.6.36 because it seemed harmless and I didn't
want to try to push more than absolutely necessary.

However, we recently fixed a bug in our gcc that had been causing
"-gdwarf2" not to be passed to the assembler, and passing this flag causes
an erroneous assembler failure in the presence of code in a data section,
sometimes.  While we'd like to track down the bug in the assembler,
we'd also like to make sure 2.6.36 builds with the current toolchain,
so I'm removing this dead code as well.

Thomas Pollet points out that the 'end' variable is broken.  It was
computed based on start/size before they were page-aligned, and as such
doesn't actually match any of the other actions we take.  The overflow
test on end was also redundant, since we had already tested it with the
properly aligned version.

So just get rid of it entirely.  The one remaining use for that broken
variable can just use 'start+size' like all the other cases already did.
