This change enables the config option ARCH_ENABLE_HUGEPAGE_MIGRATION depending on whether the platform has got ARCH_WANT_GENERAL_HUGETLB or not along with config option MIGRATION. In turn, it turns on the 'hugepage_migration_supported' function which is checked for feature presence during HugeTLB page migration and clears the way.
