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
Contributions of this patchset are: 1. unify two hugetlb alloc functions. As a result, one is remained. 2. make one external hugetlb alloc function to internal one. 3. unify three functions for migration target allocation.
The patchset is based on next-20200703 + revert v3 of this patchset.
