Pull arm64 fixes from Will Deacon:
"The main changes are a fix to the way in which we manage the access
flag setting for mappings using the contiguous bit and a fix for a
hang on the kexec/hibernation path.
Summary:
- Fix kexec/hibernation hang due to bogus read-only mappings
- Fix sparse warnings in our cmpxchg() implementation
- Prevent runtime-const being used in modules, just like x86
- Fix broken elision of access flag modifications for contiguous
entries on systems without support for hardware updates
- Fix a broken SVE selftest that was testing the wrong instruction"
