linux-yocto/4.4: fix PAT for 32bit x86

Browse Source 
Integrating the following mainline destined commits to fix PAT issues with
32bit x86 and qemu:

  bc22b90fb583 x86/pat: Document the PAT initialization sequence
  c534b1ec1991 x86/xen, pat: Remove PAT table init code from Xen
  cd47692e804f x86/mtrr: Fix PAT init handling when MTRR is disabled
  039434bdc165 x86/mtrr: Fix Xorg crashes in Qemu sessions
  c08196e8064c x86/mm/pat: Replace cpu_has_pat with boot_cpu_has()
  6928fce8c766 x86/mm/pat: Add pat_disable() interface
  3163c8d5468d x86/mm/pat: Add support of non-default PAT MSR setting

With this change applied, we once again have working graphics and no special
work arounds.
