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