[PATCH v3 03/26] MIPS: sgi-ip27: ensure node_possible_map only contains valid nodes

[Mike Rapoport]

From: "Mike Rapoport (Microsoft)" <r...@kernel.org>

For SGI IP27 machines node_possible_map is statically set to
NODE_MASK_ALL and it is not updated during NUMA initialization.

Ensure that it only contains nodes present in the system.
