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.
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
