Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky:
"The bulk of the patches for the 3.13 merge window.
Heiko spent quite a bit of work to improve the code generation for the
kernel. That includes the exploitation of the interlocked-access
facility for the atomics and bitops implementation and the improvement
for the -march and -mtune compiler settings.
Another important change is the removal of the user_mode=home option,
user processes now always run in primary space. The storage keys are
not initialized at system startup any more, with that the storage key
removal work is complete. For the PCI support the hibernation hooks
have been implemented.
And as usual cleanup and fixes"
