Subject: [PATCH v3] arm64: NUMA: Kconfig: Increase NODES_SHIFT to 4
The current arm64 default config limits max NUMA nodes available on
system to 4 (NODES_SHIFT = 2). Today's arm64 systems can reach or
exceed 16 NUMA nodes. To accomodate current hardware and to fit
NODES_SHIFT within page flags on arm64, increase NODES_SHIFT to 4.
Discussion on v1 of the patch:
