This patchset clean-up the migration target allocation functions.
* Changes on v4
- use full gfp_mask
- use memalloc_nocma_{save,restore} to exclude CMA memory
- separate __GFP_RECLAIM handling for THP allocation
- remove more wrapper functions
* Changes on v3
- As Vlastimil suggested, do not introduce alloc_control for hugetlb functions
- do not change the signature of migrate_pages()
- rename alloc_control to migration_target_control
* Changes on v2
- add acked-by tags
- fix missing compound_head() call for patch #3
- remove thisnode field on alloc_control and use __GFP_THISNODE directly
- fix missing __gfp_mask setup for patch
"mm/hugetlb: do not modify user provided gfp_mask"
* Cover-letter
