Linus Torvalds 68e3e92620 Revert "mm: compaction: handle incorrect MIGRATE_UNMOVABLE type pageblocks" ... This reverts commit 5ceb9ce6fe. That commit seems to be the cause of the mm compation list corruption issues that Dave Jones reported. The locking (or rather, absense there-of) is dubious, as is the use of the 'page' variable once it has been found to be outside the pageblock range. So revert it for now, we can re-visit this for 3.6. If we even need to: as Minchan Kim says, "The patch wasn't a bug fix and even test workload was very theoretical".
