2.6.23-stable review patch. If anyone has any objections, please let us know. ------------------ From: Christoph Lameter patch 96990a4ae979df9e235d01097d6175759331e88c in mainline. Quicklists calculates the size of the quicklists based on the number of free pages. This must be the number of free pages that can be allocated with GFP_KERNEL. node_page_state() includes the pages in ZONE_HIGHMEM and ZONE_MOVABLE which may lead the quicklists to become too large causing OOM.
