From: "Mike Rapoport (Microsoft)" <rppt@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. Signed-off-by: Mike Rapoport (Microsoft) <rppt@kernel.org> --- arch/mips/sgi-ip27/ip27-smp.c | 2 ++ 1 file changed, 2 insertions(+)
