Pull s390 fixes from Martin Schwidefsky:
"A couple of bug fixes. I keep the fingers crossed that we now got
transparent huge pages ready for prime time."
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
s390/cio: fix length calculation in idset.c
s390/sclp: fix addressing mode clobber
s390: Move css limits from drivers/s390/cio/ to include/asm/.
s390/thp: respect page protection in pmd_none() and pmd_present()
