Patch series "mm: remove __ARCH_HAS_5LEVEL_HACK", v4. These patches convert several architectures to use page table folding and remove __ARCH_HAS_5LEVEL_HACK along with include/asm-generic/5level-fixup.h and include/asm-generic/pgtable-nop4d-hack.h. With that we'll have a single and consistent way of dealing with page table folding instead of a mix of three existing options. The changes are mostly about mechanical replacement of pgd accessors with p4d ones and the addition of higher levels to page table traversals. This patch (of 14): h8300 is a nommu architecture and does not require fixup for upper layers of the page tables because it is already handled by the generic nommu implementation.
