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)
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: Fix KASAN random tag seed initialization
arm64: ACPI: NUMA: initialize all values of acpi_early_node_map to NUMA_NO_NODE
arm64: uaccess: correct thinko in __get_mem_asm()
