#     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"
