[PATCH 0/4] KVM: x86: Kill off pdptrs_changed()

[Sean Christopherson <seanjc@google.com>]

Remove pdptrs_changed(), which is mostly dead anyways, and the few bits
that are still thrashing are useless.

This conflicts with Maxim's work to migrate PDPTRs out-of-band, but I
think it will conflict in a good way as the "skip load_pdptrs()"
logic for the out-of-band case won't have to juggle this legacy crud.

Sean Christopherson (4):
  KVM: nVMX: Drop obsolete (and pointless) pdptrs_changed() check
  KVM: nSVM: Drop pointless pdptrs_changed() check on nested transition
  KVM: x86: Always load PDPTRs on CR3 load for SVM w/o NPT and a PAE
    guest
  KVM: x86: Unexport kvm_read_guest_page_mmu()
