Subject: [PATCH v2 0/9] PVH v2 support (domU)

PVH v2 support for unprivileged guests.

Now that we decided to defer ACPI CPU hotplug until we understand better
what to do about it in dom0 I am sending v2 with PV-style CPU hotplug, with
v1 comments addressed.


Boris Ostrovsky (9):
  x86/boot/32: Convert the 32-bit pgtable setup code from assembly to C
  xen/x86: Remove PVH support
  xen/pvh: Import PVH-related Xen public interfaces
  xen/pvh: Bootstrap PVH guest
  xen/pvh: Prevent PVH guests from using PIC, RTC and IOAPIC
  xen/pvh: Initialize grant table for PVH guests
  xen/pvh: PVH guests always have PV devices
  xen/pvh: Enable CPU hotplug
  xen/pvh: Use Xen's emergency_restart op for PVH guests
