[PATCH v10 01/14] mm/gup: don't pin migrated cma pages in movable zone

[Pavel Tatashin]

In order not to fragment CMA the pinned pages are migrated. However,
they are migrated to ZONE_MOVABLE, which also should not have pinned pages.

Remove __GFP_MOVABLE, so pages can be migrated to zones where pinning
is allowed.
