  - mm/vmemmap/devdax: fix kernel crash when probing devdax devices commit 4917f55b4ef9 (mm/sparse-vmemmap:
    improve memory savings for compound devmaps) added support for using optimized vmmemap for devdax
    devices. But how vmemmap mappings are created are architecture specific. For example, powerpc with hash
    translation doesn't have vmemmap mappings in init_mm page table instead they are bolted table entries in
    the hardware page table vmemmap_populate_compound_pages() used by vmemmap optimization code is not aware
    of these architecture-specific mapping. Hence allow architecture to opt for this feature. I selected
    architectures supporting HUGETLB_PAGE_OPTIMIZE_VMEMMAP option as also supporting this feature. This patch
    fixes the below crash on ppc64. BUG: Unable to handle kernel data access on write at 0xc00c000100400038
