Merge tag 'arm64-stable' of git://git./linux/kernel/git/cmarinas/linux-aarch64

Pull ARM64 fixes from Catalin Marinas:
 - Remove preempt_count modifications in the arm64 IRQ handling code
   since that's already dealt with in generic irq_enter/irq_exit
 - PTE_PROT_NONE bit moved higher up to avoid overlapping with the
   hardware bits (for PROT_NONE mappings which are pte_present)
 - Big-endian fixes for ptrace support
 - Asynchronous aborts unmasking while in the kernel
 - pgprot_writecombine() change to create Normal NonCacheable memory
   rather than Device GRE
