These patches implement PML on top of EPT A/D emulation
(ae1e2d1082ae).

When dirty bit is being set, we write the gpa to the
buffer provided by L1. If the index overflows, we just
change the exit reason before running L1.

Bandan Das (3):
  kvm: x86: Add a hook for arch specific dirty logging emulation
  nVMX: Implement emulated Page Modification Logging
  nVMX: Advertise PML to L1 hypervisor
