Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"There are some significant fixes in here for FP state corruption,
hardware access/dirty PTE corruption and an erratum workaround for the
Falkor CPU.
I'm hoping that things finally settle down now, but never say never...
Summary:
- Fix FPSIMD context switch regression introduced in -rc2
- Fix ABI break with SVE CPUID register reporting
- Fix use of uninitialised variable
- Fixes to hardware access/dirty management and sanity checking
- CPU erratum workaround for Falkor CPUs
- Fix reporting of writeable+executable mappings
- Fix signal reporting for RAS errors"
