#     Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
#     
#     Pull arm64 fixes from Catalin Marinas:
#     
#      - Set the minimum GCC version to 5.1 for arm64 due to earlier compiler
#        bugs.
#     
#      - Make atomic helpers __always_inline to avoid a section mismatch when
#        compiling with clang.
#     
#      - Fix the CMA and crashkernel reservations to use ZONE_DMA (remove the
#        arm64_dma32_phys_limit variable, no longer needed with a dynamic
#        ZONE_DMA sizing in 5.11).
#     
#      - Remove redundant IRQ flag tracing that was leaving lockdep
#        inconsistent with the hardware state.
#     
#      - Revert perf events based hard lockup detector that was causing
#        smp_processor_id() to be called in preemptible context.
#     
#      - Some trivial cleanups - spelling fix, renaming S_FRAME_SIZE to
#        PT_REGS_SIZE, function prototypes added.
