[PATCH v2 0/3] nVMX: Emulated Page Modification Logging for Nested Virtualization

[Bandan Das]

v2:
2/3: Clear out all bits except bit 12
3/3: Slightly modify an existing comment, honor L0's
PML setting when clearing it for L1

v1:
http://www.spinics.net/lists/kvm/msg149247.html

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.

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