Should we at least go for add-__gfp_movable-for-callers-to-flag-allocations-from-high-memory-that-may-be-migrated.patch create-the-zone_movable-zone.patch allow-huge-page-allocations-to-use-gfp_high_movable.patch handle-kernelcore=-generic.patch in 2.6.23? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
