Please reference it if more information is needed. In this patchset, the memory of the CMA area is managed by using the ZONE_MOVABLE. Since there is another type of the memory in this zone, we need to maintain a migratetype for the CMA memory to account the number of the CMA memory. So, unlike previous patchset, there is less deletion of the code. Otherwise, there is no big change. Motivation of this patchset is described in the commit description of the patch "mm/cma: manage the memory of the CMA area by using the ZONE_MOVABLE". Please refer it for more information. This patchset is based on linux-next-20170822 plus "mm/page_alloc: don't reserve ZONE_HIGHMEM for ZONE_MOVABLE". Thanks.
