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().
