Naoya Horiguchi 290408d4a2 hugetlb: hugepage migration core ... This patch extends page migration code to support hugepage migration. One of the potential users of this feature is soft offlining which is triggered by memory corrected errors (added by the next patch.) Todo: - there are other users of page migration such as memory policy, memory hotplug and memocy compaction. They are not ready for hugepage support for now. ChangeLog since v4: - define migrate_huge_pages() - remove changes on isolation/putback_lru_page() ChangeLog since v2: - refactor isolate/putback_lru_page() to handle hugepage - add comment about race on unmap_and_move_huge_page() ChangeLog since v1: - divide migration code path for hugepage - define routine checking migration swap entry for hugetlb - replace "goto" with "if/else" in remove_migration_pte() Signed-off-by: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com> Signed-off-by: Jun'ichi Nomura <j-nomura@ce.jp.nec.com> Acked-by: Mel Gorman <mel@csn.ul.ie> Signed-off-by: Andi Kleen <ak@linux.intel.com>		2010-10-08 09:32:45 +02:00
