Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 update from Martin Schwidefsky:
"Add support to generate code for the latest machine zEC12, MOD and XOR
instruction support for the BPF jit compiler, the dasd safe offline
feature and the big one: the s390 architecture gets PCI support!!
Right before the world ends on the 21st ;-)"
