page-allocator: clear N_HIGH_MEMORY map before we set it again
SRAT tables may contains nodes of very small size. The arch code may decide to not activate such a node. However, currently the early boot code sets N_HIGH_MEMORY for such nodes. These nodes therefore seem to be active although these nodes have no present pages. For 64bit N_HIGH_MEMORY == N_NORMAL_MEMORY, so that works for 64 bit too Signed-off-by: Yinghai Lu <Yinghai@kernel.org> Tested-by: Jack Steiner <steiner@sgi.com> Acked-by: Christoph Lameter <cl@linux-foundation.org> Cc: Mel Gorman <mel@csn.ul.ie> Cc: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
