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

Pull arm64 fixes (and cleanups) from Catalin Marinas:
 "Various arm64 fixes:

   - suspicious RCU usage warning
   - BPF (out of bounds array read and endianness conversion)
   - perf (of_node usage after of_node_put, cpu_pmu->plat_device
     assignment)
   - huge pmd/pud check for value 0
   - rate-limiting should only take unhandled signals into account

  Clean-up:

   - incorrect use of pgprot_t type
   - unused header include
   - __init annotation to arm_cpuidle_init
   - pr_debug instead of pr_error for disabled GICC entries in
     ACPI/MADT"
