#     
#     Pull arm64 fixes from Will Deacon:
#      "A few arm64 fixes came in this week, specifically fixing some nasty
#       truncation of return values from firmware calls and resolving a
#       VM_BUG_ON due to accessing uninitialised struct pages corresponding to
#       NOMAP pages.
#     
#       Summary:
#     
#        - Fix typos in SVE documentation
#     
#        - Fix type-checking and implicit truncation for SMCCC calls
#     
#        - Force CONFIG_HOLES_IN_ZONE=y so that SLAB doesn't fall over NOMAP
#          regions"
