    Pull arm64 fixes from Will Deacon:
     "Half of this is broken hardware (AMU counters and TLB invalidation)
      and the other half is broken software (frequency scaling and signals).
      So it seems as though we're all as bad as each other.

      The AMU workaround is a little noisy, as it refactors an existing
      workaround so that it can more easily be applied to additional CPUs.

      Summary:

       - Fix handling of CPU erratum #2645198 when batching pte updates

       - Fix truncation of CPU frequency calculation by using 64-bit
         arithmetic in arch_freq_get_on_cpu()

       - Work around AMU erratum #3821522 on Cortex-A725

       - Fix panic when trying to restore an SVE sigframe on a CPU that only
         supports SME"
