Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Martin Schwidefsky:
 "The main new feature is machine support for System zEC12 including
  transactional memory, runtime instrumentation, support for scm block
  devices via eadm subchannels, and support for CEX4 crypto cards.

  In addition there are some nice improvements: bpf jit compiler, arch
  backend for cmpxchg_double, relative exception table entries, dasd
  partition detection independent from the dasd driver ioctls, and cpu
  cache information in /proc/cpuinfo and /sys/device/cpu.

  And last but not least a series of cleanup patches from Heiko."

Fix up trivial add-add conflict in arch/s390/Kconfig due to commit
b952741c8079 ("cputime: Generalize CONFIG_VIRT_CPU_ACCOUNTING")
