Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- Re-instate the CPUMASK_OFFSTACK option for arm64 when NR_CPUS > 256.
The bug that led to the initial revert was the cpufreq-dt code not
using zalloc_cpumask_var().
- Make the STARFIVE_STARLINK_PMU config option depend on 64BIT to
prevent compile-test failures on 32-bit architectures due to missing
writeq().
