Subject: [PATCH v2 0/6] 32-bit PVH domU support

A set of PVH-related patches.

The first patch is x86-64 ABI fix for PVH guests. The second is a small update
that removes redundant memset (both on PV and PVH code paths)

The rest is to enable non-privileged 32-bit PVH guests. This requires hypervisor
patches from http://lists.xenproject.org/archives/html/xen-devel/2015-07/msg02229.html

Changes in v3:
* Removed second argument to xen_pvh_early_cpu_init() per Konrad's suggestion
  (patch 1)
* Replaced segment updates done in assembly with loadsegment() macros (patch 4)


Boris Ostrovsky (6):
  xen/x86/pvh: Save %rbx in xen_pvh_early_cpu_init()
  xen/x86: Remove unnecessary memset() call
  xen/x86/pvh: Properly set page tables for 32-bit PVH guests
  xen/x86/pvh: Set up descriptors for 32-bit PVH guests
  xen/x86/pvh: Add 32-bit PVH initialization code
  xen/x86/pvh: Allow building 32-bit PVH guests
