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

Pull arm64 fixes from Catalin Marinas:

 - Fix the arm64 __get_mem_asm() to use the _ASM_EXTABLE_##type##ACCESS()
   macro instead of the *_ERR() one in order to avoid writing -EFAULT to
   the value register in case of a fault

 - Initialise all elements of the acpi_early_node_map[] to NUMA_NO_NODE.
   Prior to this fix, only the first element was initialised

 - Move the KASAN random tag seed initialisation after the per-CPU areas
   have been initialised (prng_state is __percpu)
