Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"I think the main one is fixing the dynamic SCS patching when full LTO
is enabled (clang was silently getting this horribly wrong), but it's
all good stuff.
Rob just pointed out that the fix to the workaround for erratum
#2966298 might not be necessary, but in the worst case it's harmless
and since the official description leaves a little to be desired here,
I've left it in.
Summary:
- Fix shadow call stack patching with LTO=full
- Fix voluntary preemption of the FPSIMD registers from assembly code
- Fix workaround for A520 CPU erratum #2966298 and extend to A510
- Fix SME issues that resulted in corruption of the register state
- Minor fixes (missing includes, formatting)"
