Baolin Wang 231f8c7127 mm: page_alloc: allowing mTHP compaction to capture the freed page directly
Currently, compaction_capture() does not allow lower-order allocations to
directly capture the movable free pages, even though lower-order
allocations might also be requesting movable pages, that can lead to more
compaction scanning.  And, with the enablement of mTHP, such situations
will become more common.

Thus allowing lower-order (mTHP) allocations of movable page types
directly capture the movable free pages can avoid unnecessary compaction
scanning, meanwhile that won't pollute the movable pageblock.  With
testing 1M mTHP compaction, it can be seen that compaction scanning is
significantly reduced.
