Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky:
"Mostly cleanups and bug-fixes, with two exceptions.
The first is lazy flushing of I/O-TLBs for PCI to improve performance,
the second is software dirty bits in the pmd for the madvise-free
implementation"
