#     Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
#     
#     Pull arm64 fixes from Catalin Marinas:
#     
#      - Fix a build error with CONFIG_CFI_CLANG + CONFIG_FTRACE when
#        CONFIG_FUNCTION_GRAPH_TRACER is not enabled.
#     
#      - Fix a BUG_ON triggered by the page table checker due to incorrect
#        file_map_count for non-leaf pmd/pud (the arm64
#        pmd_user_accessible_page() not checking whether it's a leaf entry).
#
