Subject: [PATCH 4.14 STABLE 0/2] KVM: x86: PAE related bug fixes

The primary goal is to land patch 2/2 (from Paolo), which fixes a reported
crash when running 64-bit KVM guests on systems without unrestricted guest
support.

Attempting to cherry-pick Paolo's patch revealed that a similar PAE bug
fix from Junaid was also missing.  Grab Junaid's patch as a prerequisite,
even though it will effectively be overwritten, so that Paolo's upstream
fix can be applied without modification (sans the vmx.c split in 5.x).

Junaid Shahid (1):
  kvm: mmu: Don't read PDPTEs when paging is not enabled

Paolo Bonzini (1):
  KVM: x86: introduce is_pae_paging
