[PATCH] s390: fix in-user atomic futex operation.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
__futex_atomic_op needs to do an atomic operation in the user address space,
not the kernel address space. Add the missing sacf 256/sacf 0 to switch to
the secondary mode before doing the compare-and-swap. In addition add
another fixup for catch specification exceptions if the compare-and-swap
address is not aligned.
