      Pull arm64 updates from Will Deacon:
       "The big highlight is support for the Scalable Vector Extension (SVE)
        which required extensive ABI work to ensure we don't break existing
        applications by blowing away their signal stack with the rather large
        new vector context (<= 2 kbit per vector register). There's further
        work to be done optimising things like exception return, but the ABI
        is solid now.
        Much of the line count comes from some new PMU drivers we have, but
        they're pretty self-contained and I suspect we'll have more of them in
        Plenty of acronym soup here:
         - initial support for the Scalable Vector Extension (SVE)
         - improved handling for SError interrupts (required to handle RAS
         - enable GCC support for 128-bit integer types
         - remove kernel text addresses from backtraces and register dumps
         - use of WFE to implement long delay()s
         - ACPI IORT updates from Lorenzo Pieralisi
         - perf PMU driver for the Statistical Profiling Extension (SPE)
         - perf PMU driver for Hisilicon's system PMUs
         - misc cleanups and non-critical fixes"
