Subject: [PATCH 0/8] 5-level paging enabling for v4.14

Hi,

As Ingo requested, I'm resending the rebased patchset after merge window to be
queued for v4.14.

The patches was reordered and few more fixes added: for Xen and dump_pagetables.

Please consider applying.

Kirill A. Shutemov (8):
  x86/dump_pagetables: Generalize address normalization
  x86/dump_pagetables: Fix printout of p4d level
  x86/xen: Redefine XEN_ELFNOTE_INIT_P2M using PUD_SIZE * PTRS_PER_PUD
  x86/mm: Rename tasksize_32bit/64bit to task_size_32bit/64bit
  x86/mpx: Do not allow MPX if we have mappings above 47-bit
  x86/mm: Prepare to expose larger address space to userspace
  x86/mm: Allow userspace have mapping above 47-bit
  x86: Enable 5-level paging support
