This adds new tests validating arch page table helpers for these following core memory features. These tests create and test specific mapping types at various page table levels. * SPECIAL mapping * PROTNONE mapping * DEVMAP mapping * SOFTDIRTY mapping * SWAP mapping * MIGRATION mapping * HUGETLB mapping
For testing HUGETLB mappings, you also have to include tests of hugepd functions/helpers. Not all archictures have hugepage size which matches with page tables levels (e.g. powerpc). Those architectures use hugepd_t.
