Migration normally requires a call to migrate_prep() as a preparation step. This schedules work on all CPUs for pagevecs to be drained. This makes sense for move_pages and memory hot-remove but is unnecessary for memory compaction. To avoid queueing work on multiple CPUs, this patch introduces migrate_prep_local() which drains just local pagevecs. This patch can be either merged with mmcompaction-memory-compaction-core.patch or placed immediately after it to clarify why migrate_prep_local() was introduced.
