#     Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
#     
#     Pull arm64 fixes from Will Deacon:
#      "Summary below, but it's all reasonably straightforward. There are some
#       more fixes on the horizon, but nothing disastrous yet.
#     
#       Summary:
#     
#        - Fix build when KASLR is enabled but CONFIG_ARCH_RANDOM is not set
#     
#        - Fix context-switching of SSBS state on systems that implement it
#     
#        - Fix spinlock compiler warning introduced during the merge window
#     
#        - Fix incorrect header inclusion (linux/clk-provider.h)
#     
#        - Use SYSCTL_{ZERO,ONE} instead of rolling our own static variables
#     
#        - Don't scream if optional SMMUv3 PMU irq is missing
#     
#        - Remove some unused function prototypes"
#
