The patch is interesting because it would allow the moving of page table
pages into MOVABLE sections and reduce the size of the UNMOVABLE
allocations signficantly (Ross: We need some numbers here). This in turn
improves the success of the antifrag methods. May also improve lumpy
reclaim if it can be adapted to move page table pages out of the way.
