Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"This addresses a couple of issues found with RT, a broken initrd
message in the console log and a simple performance fix for some MMC
workloads.
Summary:
- A couple of locking fixes for RT kernels
- Avoid printing bogus initrd warnings when initrd isn't present
- Performance fix for random mmap file readahead
- Typo fix"
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: replace read_lock to rcu lock in call_break_hook
arm64: Don't relocate non-existent initrd
arm64: convert patch_lock to raw lock
arm64: readahead: fault retry breaks mmap file read random detection
arm64: debug: Fix typo in debug-monitors.c
