From: Mike Rapoport <rppt@xxxxxxxxxxxxx> Hi, These patches convert several architectures to use page table folding and remove __ARCH_HAS_5LEVEL_HACK along with include/asm-generic/5level-fixup.h. The changes are mostly about mechanical replacement of pgd accessors with p4d ones and the addition of higher levels to page table traversals. All the patches were sent separately to the respective arch lists and maintainers hence the "v2" prefix.
