#     
#     Pull arm64 fixes from Will Deacon:
#      "These are all very simple and self-contained, although the CFI
#       jump-table fix touches the generic linker script as that's where the
#       problematic macro lives.
#     
#        - Fix false positive "sleeping while atomic" warning resulting from
#          the kPTI rework taking a mutex too early.
#     
#        - Fix possible overflow in AMU frequency calculation
#     
#        - Fix incorrect shift in CMN PMU driver which causes problems with
#          newer versions of the IP
#     
#        - Reduce alignment of the CFI jump table to avoid huge kernel images
#          and link errors with !4KiB page size configurations"
