Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- Update the compat layer to allow single-byte watchpoints on all
addresses (similar to the native support)
- arm_pmu: fix the restoration of the counters on the
CPU_PM_ENTER_FAILED path
- Fix build regression with vDSO and Makefile not stripping
CROSS_COMPILE_COMPAT
- Fix the CTR_EL0 (cache type register) sanitisation on heterogeneous
machines (e.g. big.LITTLE)
- Fix the interrupt controller priority mask value when pseudo-NMIs are
enabled
- arm64 kprobes fixes: recovering of the PSTATE.D flag in the
single-step exception handler, NOKPROBE annotations for
unwind_frame() and walk_stackframe(), remove unneeded
rcu_read_lock/unlock from debug handlers
- Several gcc fall-through warnings
- Unused variable warnings
