- Fix cpufreq warning due to attempting a cross-call with interrupts
masked when reading local AMU counters.
- Fix DEBUG_PREEMPT warning from the delay loop when it tries to access
per-cpu errata workaround state for the virtual counter.
- Re-jig and optimise our TLB invalidation errata workarounds in
preparation for more hardware brokenness.
- Fix GCS mappings to interact properly with PROT_NONE and to avoid
corrupting the pte on CPUs with FEAT_LPA2.
- Fix ioremap_prot() to extract only the memory attributes from the
user pte and ignore all the other 'prot' bits.

Pull arm64 fixes from Will Deacon:
"The diffstat is dominated by changes to our TLB invalidation errata
handling and the introduction of a new GCS selftest to catch one of
the issues that is fixed here relating to PROT_NONE mappings.
