#     Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
#     
#     Pull arm64 updates from Catalin Marinas:
#      "Apart from the core arm64 and perf changes, the Spectre v4 mitigation
#       touches the arm KVM code and the ACPI PPTT support touches drivers/
#       (acpi and cacheinfo). I should have the maintainers' acks in place.
#     
#       Summary:
#     
#        - Spectre v4 mitigation (Speculative Store Bypass Disable) support
#          for arm64 using SMC firmware call to set a hardware chicken bit
#     
#        - ACPI PPTT (Processor Properties Topology Table) parsing support and
#          enable the feature for arm64
#     
#        - Report signal frame size to user via auxv (AT_MINSIGSTKSZ). The
#          primary motivation is Scalable Vector Extensions which requires
#          more space on the signal frame than the currently defined
#          MINSIGSTKSZ
#     
#        - ARM perf patches: allow building arm-cci as module, demote
#          dev_warn() to dev_dbg() in arm-ccn event_init(), miscellaneous
#          cleanups
#     
#        - cmpwait() WFE optimisation to avoid some spurious wakeups
#     
#        - L1_CACHE_BYTES reverted back to 64 (for performance reasons that
#          have to do with some network allocations) while keeping
#          ARCH_DMA_MINALIGN to 128. cache_line_size() returns the actual
#          hardware Cache Writeback Granule
#     
#        - Turn LSE atomics on by default in Kconfig
#     
#        - Kernel fault reporting tidying
#     
#        - Some #include and miscellaneous cleanups"
