#     Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
#     
#     Pull arm64 fixes from Catalin Marinas:
#      "Fixes and cpucaps.h automatic generation:
#     
#        - Generate cpucaps.h at build time rather than carrying lots of
#          #defines. Merged at -rc1 to avoid some conflicts during the merge
#          window.
#     
#        - Initialise RGSR_EL1.SEED in __cpu_setup() as it may be left as 0
#          out of reset and the IRG instruction would not function as expected
#          if only the architected pseudorandom number generator is
#          implemented.
#     
#        - Fix potential race condition in __sync_icache_dcache() where the
#          PG_dcache_clean page flag is set before the actual cache
#          maintenance.
#     
#        - Fix header include in BTI kselftests"
