#     Pull more arm64 updates from Catalin Marinas:
#      "A mix of fixes and clean-ups that turned up too late for the first
#       pull request:
#     
#        - Restore terminal stack frame records. Their previous removal caused
#          traces which cross secondary_start_kernel to terminate one entry
#          too late, with a spurious "0" entry.
#     
#        - Fix boot warning with pseudo-NMI due to the way we manipulate the
#          PMR register.
#     
#        - ACPI fixes: avoid corruption of interrupt mappings on watchdog
#          probe failure (GTDT), prevent unregistering of GIC SGIs.
#     
#        - Force SPARSEMEM_VMEMMAP as the only memory model, it saves with
#          having to test all the other combinations.
#     
#        - Documentation fixes and updates: tagged address ABI exceptions on
#          brk/mmap/mremap(), event stream frequency, update booting
#          requirements on the configuration of traps"
