#     Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
#     
#     Pull arm64 fixes from Will Deacon:
#      "These are almost exclusively related to CPU errata in CPUs from
#       Broadcom and Qualcomm where the workarounds were either not being
#       enabled when they should have been or enabled when they shouldn't have
#       been.
#     
#       The only "interesting" fix is ensuring that writeable, shared mappings
#       are initially mapped as clean since we inadvertently broke the logic
#       back in v4.14 and then noticed the problem via code inspection the
#       other day.
#     
#       The only critical issue we have outstanding is a sporadic NULL
#       dereference in the scheduler, which doesn't appear to be
#       arm64-specific and PeterZ is tearing his hair out over it at the
#       moment.
#     
#       Summary:
#     
#        - Enable CPU errata workarounds for Broadcom Brahma-B53
#     
#        - Enable CPU errata workarounds for Qualcomm Hydra/Kryo CPUs
#     
#        - Fix initial dirty status of writeable, shared mappings"
