commit f8df73388ee25b5e5f1d26249202e7126ca8139d upstream. Introduce helpers to abstract architectural handling of the conversion of pfn to page table entries and marking a PMD page table entry as a block entry. The helpers are introduced in preparation for supporting PUD hugepages at stage 2 - which are supported on arm64 but do not exist on arm.
