[Xen-devel] [PATCH v2 00/11] HVMlite domU support

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

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)
