Subject: [PATCH v2 00/13] mm: remove __ARCH_HAS_5LEVEL_HACK

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.

Geert Uytterhoeven (1):
  sh: fault: Modernize printing of kernel messages

Mike Rapoport (12):
  arm/arm64: add support for folded p4d page tables
  h8300: remove usage of __ARCH_USE_5LEVEL_HACK

  ia64: add support for folded p4d page tables
  nios2: add support for folded p4d page tables
  openrisc: add support for folded p4d page tables
  powerpc: add support for folded p4d page tables
  sh: drop __pXd_offset() macros that duplicate pXd_index() ones
  sh: add support for folded p4d page tables
  unicore32: remove __ARCH_USE_5LEVEL_HACK
  asm-generic: remove pgtable-nop4d-hack.h
  mm: remove __ARCH_HAS_5LEVEL_HACK and include/asm-generic/5level-fixup.h
