Re: [PATCH v2] arm64/mm: return cpu_all_mask when node is NUMA_NO_NODE

The @node passed to cpumask_of_node() can be NUMA_NO_NODE, in that
case it will trigger the following WARN_ON(node >= nr_node_ids) due to
mismatched data types of @node and @nr_node_ids. Actually we should
return cpu_all_mask just like most other architectures do if passed
NUMA_NO_NODE.

Also add a similar check to the inline cpumask_of_node() in numa.h.

Applied to arm64 (for-next/misc), thanks!
