Subject: [PATCH 0/8] PVH v2 support

(Resending with proper mailing lists included)

PVH v2 support for unprivileged guests.

Previous version was posted long time ago. Major changes:
1. Drop PVH v1 support
2. Enable ACPI. This allows us to use much more of native code and
   results in making this series much simpler (for example, PV-style
   VCPU bringup is no longer necessary).
3. Refactor 32-bit pagetable setup from native code (by Matt Fleming)

This has been tested on Intel/AMD, both 32- and 64-bit, including CPU
hotplug and save/restore. Compile-tested for ARM.


Boris Ostrovsky (8):
  xen/x86: Remove PVH support
  x86/head: Refactor 32-bit pgtable setup
  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
