[PATCH v4 07/11] mm/gup: use a standard migration target allocation callback

From: Joonsoo Kim There is a well-defined migration target allocation callback. It's mostly similar with new_non_cma_page() except considering CMA pages. This patch adds a CMA consideration to the standard migration target allocation callback and use it on gup.c. Acked-by: Vlastimil Babka
