Merge tag 's390-7.0-6' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Vasily Gorbik:

 - Add array_index_nospec() to syscall dispatch table lookup to prevent
   limited speculative out-of-bounds access with user-controlled syscall
   number

 - Mark array_index_mask_nospec() __always_inline since GCC may emit an
   out-of-line call instead of the inline data dependency sequence the
   mitigation relies on

 - Clear r12 on kernel entry to prevent potential speculative use of
   user value in system_call, ext/io/mcck interrupt handlers

* tag 's390-7.0-6' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  s390/entry: Scrub r12 register on kernel entry
  s390/syscalls: Add spectre boundary for syscall dispatch table
  s390/barrier: Make array_index_mask_nospec() __always_inline
