Subject: mm: compaction: have CONFIG_COMPACTION depend on HUGETLB_PAGE instead of HUGETLBFS
From: Mel Gorman <mel@xxxxxxxxx>
There is a strong coupling between HUGETLB_PAGE and HUGETLBFS but in theory
there can be alternative interfaces to huge pages than HUGETLB_PAGE. This
patch makes CONFIG_COMPACTION depend on the right thing.
This is a fix to the patch "Allow CONFIG_MIGRATION to be set without
CONFIG_NUMA or memory hot-remove" and should be merged together.
