Subject: [PATCH v2 00/11] HVMlite domU support

This series introduces HVMlite support for unprivileged guests.

It has been tested on Intel/AMD, both 32- and 64-bit, including CPU on- and
offlining and save/restore. (Restore will result in APIC write warnings
which exist now for 32-bit PV guests as well so I didn't address this in
this series)

Compile-tested on ARM

v2:
* Dropped first patch (don't use initial_page_table/initial_pg_pmd and start_secondary)
* Much simplified kernel init code (after realizing that xen_hvm_guest_init()/
  init_hvm_pv_info() already do most of it). As result, factoring ot of xen_start_kernel()
  is no longer necessary. (patch 3)
* Dropped pcifront use until we decide that we *are* using it. (patch 5)


Boris Ostrovsky (11):
  xen/hvmlite: Import hvmlite-related Xen public interfaces
  xen/hvmlite: Bootstrap HVMlite guest
  xen/hvmlite: Initialize HVMlite kernel
  xen/hvmlite: Allow HVMlite guests delay initializing grant table
  xen/hvmlite: HVMlite guests always have PV devices
  xen/hvmlite: Prepare cpu_initialize_context() routine for HVMlite SMP
  xen/hvmlite: Initialize context for secondary VCPUs
  xen/hvmlite: Extend APIC operations for HVMlite guests
  xen/hvmlite: Use x86's default timer init for HVMlite guests
  xen/hvmlite: Boot secondary CPUs
  xen/hvmlite: Enable CPU on-/offlining
