[PATCH v1 00/12] HVMlite domU support

[Boris Ostrovsky]

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

Boris Ostrovsky (12):
  x86/smp: Make start_secondary() and initial_pg_pmd visible globally
  xen/hvmlite: Factor out common kernel init code
  xen/hvmlite: Import hvmlite-related Xen public interfaces
  xen/hvmlite: Bootstrap HVMlite guest
  xen/hvmlite: Allow HVMlite guests delay initializing grant table
  xen/hvmlite: Initialize PCI
  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
