arm64: Make debug exception handlers visible from RCU (2019-08-02 11:56:01 +0100)

----------------------------------------------------------------
arm64 fixes:

- 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

----------------------------------------------------------------
Anders Roxell (2):
arm64: smp: Mark expected switch fall-through
arm64: module: Mark expected switch fall-through
