    Linus Torvalds authored
    Pull arm64 updates from Will Deacon:
     "It's a bit all over the place this time with no "killer feature" to
      speak of.  Support for mismatched cache line sizes should help people
      seeing whacky JIT failures on some SoCs, and the big.LITTLE perf
      updates have been a long time coming, but a lot of the changes here
      are cleanups.
    
      We stray outside arch/arm64 in a few areas: the arch/arm/ arch_timer
      workaround is acked by Russell, the DT/OF bits are acked by Rob, the
      arch_timer clocksource changes acked by Marc, CPU hotplug by tglx and
      jump_label by Peter (all CC'd).
    
      Summary:
    
       - Support for execute-only page permissions
       - Support for hibernate and DEBUG_PAGEALLOC
       - Support for heterogeneous systems with mismatches cache line sizes
       - Errata workarounds (A53 843419 update and QorIQ A-008585 timer bug)
       - arm64 PMU perf updates, including cpumasks for heterogeneous systems
       - Set UTS_MACHINE for building rpm packages
       - Yet another head.S tidy-up
       - Some cleanups and refactoring, particularly in the NUMA code
       - Lots of random, non-critical fixes across the board"
