Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"A few arm64 fixes came in this week, specifically fixing some nasty
truncation of return values from firmware calls and resolving a
VM_BUG_ON due to accessing uninitialised struct pages corresponding to
NOMAP pages.
Summary:
- Fix typos in SVE documentation
- Fix type-checking and implicit truncation for SMCCC calls
- Force CONFIG_HOLES_IN_ZONE=y so that SLAB doesn't fall over NOMAP
regions"
