Revision d92da1fbb72490f999b7d0e809d13d0d52dc78ac authored by Linus Torvalds on 21 March 2019, 18:48:06 UTC, committed by Linus Torvalds on 21 March 2019, 18:48:06 UTC 
Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
 
Pull arm64 fixes from Catalin Marinas:
 "Mostly fixes apart from the kprobe blacklist checking which was
  deferred because of conflicting with a fix merged after I pinned the
  arm64 for-next/core branch (f2b3d8566d81 "arm64: kprobe: Always
  blacklist the KVM world-switch code").

  Summary:

   - Update the kprobe blacklist checking for arm64. This was supposed
     to be queued during the merging window but, due to conflicts, it
     was deferred post -rc1

   - Extend the Fujitsu erratum 010001 workaround to A64FX v1r0

   - Whitelist HiSilicon Taishan v110 CPUs as not susceptible to
     Meltdown

   - Export save_stack_trace_regs()

   - Remove obsolete selection of MULTI_IRQ_HANDLER"
