Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 fixes from Catalin Marinas:
 "arm64 and perf fixes:

   - build error when accessing MPIDR_HWID_BITMASK from .S

   - fix CTR_EL0 field definitions

   - remove/disable some kernel messages on user faults (unhandled
     signals, unimplemented syscalls)

   - fix kernel page fault in unwind_frame() with function graph tracing

   - fix perf sleeping while atomic errors when booting with ACPI"
