#     Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
#     
#     Pull arm64 fixes from Will Deacon:
#      "The main thing here is a long-awaited workaround for a CPU erratum on
#       ThunderX2 which we have developed in conjunction with engineers from
#       Cavium/Marvell.
#     
#       At the moment, the workaround is unconditionally enabled for affected
#       CPUs at runtime but we may add a command-line option to disable it in
#       future if performance numbers show up indicating a significant cost
#       for real workloads.
#     
#       Summary:
#     
#        - Work around Cavium/Marvell ThunderX2 erratum #219
#     
#        - Fix regression in mlock() ABI caused by sign-extension of TTBR1 addresses
#     
#        - More fixes to the spurious kernel fault detection logic
#     
#        - Fix pathological preemption race when enabling some CPU features at boot
#     
#        - Drop broken kcore macros in favour of generic implementations
#     
#        - Fix userspace view of ID_AA64ZFR0_EL1 when SVE is disabled
#     
#        - Avoid NULL dereference on allocation failure during hibernation"
