EM64T CPUs have somewhat weird error reporting for non canonical RIPs in
SYSRET.

We can't handle any exceptions there because the exception handler would
end up running on the user stack which is unsafe.

To avoid problems any code that might end up with a user touched pt_regs
should return using int_ret_from_syscall.  int_ret_from_syscall ends up
using IRET, which allows safe exceptions.

  [PATCH] ahci: fix NULL pointer dereference detected by Coverity

* master.kernel.org:/home/rmk/linux-2.6-arm:
  [ARM] iwmmxt thread state alignment
  [ARM] 3350/1: Enable 1-wire on ARM
  [ARM] 3356/1: Workaround for the ARM1136 I-cache invalidation problem

  [ARM] Fix muldi3.S

This patch removes the reliance of iwmmxt on hand coded alignments.
Since thread_info is always 8K aligned, specifying that fpstate is
8-byte aligned achieves the same effect without needing to resort
to hand coded alignments.

This patch fixes an error in the dl2k driver's DMA mapping/unmapping.
The adapter uses the upper 16bits of the DMA address for the buffer
size.  However, this is not masked off when referencing the DMA
address, and can lead to errors by trying to free a DMA address out of
range.
