Subject: [PATCH 0/6] x86: 5-level paging enabling for v4.12, Part 1

Here's the first bunch of patches of 5-level patchset. Let's see if I'm on
right track addressing Ingo's feedback. :)

These patches prepare x86 code to be switched from <asm-generic/5level-fixup>
to <asm-generic/pgtable-nop4d.h>. It's a stepping stone for adding 5-level
paging support.

Please review and consider applying.

Kirill A. Shutemov (6):
  x86/mm: Extend headers with basic definitions to support 5-level
    paging
  x86/mm: Convert trivial cases of page table walk to 5-level paging
  x86/gup: Add 5-level paging support
  x86/ident_map: Add 5-level paging support
  x86/vmalloc: Add 5-level paging support
  x86/power: Add 5-level paging support
