Subject: [PATCH 00/19] xen/dom0: core implementation

From: Jeremy Fitzhardinge <jeremy.fitzhardinge@...rix.com>

This series implements the core part of Xen dom0 support.  Domain 0
(dom0) is the first Xen domain started on system boot, loaded by the
hypervisor itself.  Unlike a normal domain, it has direct hardware
access, and is responsible for supplying the device drivers for most
of the system's hardware.

The series covers the following areas:
 - dom0 console support
 - initialize xenbus
 - give dom0 kernel direct hardware access (both IO ports and IO mappings)
 - enable more CPU features, specifically APIC and ACPI
 - support for dom0-specific hypercalls
 - Kconfig updates to enable dom0
 - MTRR updates, to paravirtualize the mtrr via Xen

Thanks,
	J

Ian Campbell (4):
  xen: disable PAT
  xen/dom0: Use host E820 map
  xen: implement XENMEM_machphys_mapping
  xen: clear reserved bits in l3 entries given in the initial
    pagetables

Jeremy Fitzhardinge (6):
  xen dom0: Make hvc_xen console work for dom0.
  xen-dom0: only selectively disable cpu features
  xen/dom0: use _PAGE_IOMAP in ioremap to do machine mappings
  paravirt/xen: add pvop for page_is_ram
  xen/dom0: add XEN_DOM0 config option
  xen: allow enable use of VGA console on dom0

Juan Quintela (2):
  xen dom0: Initialize xenbus for dom0.
  xen dom0: Set up basic IO permissions for dom0.

Mark McLoughlin (5):
  xen mtrr: Use specific cpu_has_foo macros instead of generic
    cpu_has()
  xen mtrr: Kill some unneccessary includes
  xen mtrr: Use generic_validate_add_page()
  xen mtrr: Implement xen_get_free_region()
  xen mtrr: Add xen_{get,set}_mtrr() implementations

Stephen Tweedie (2):
  xen dom0: Add support for the platform_ops hypercall
  xen mtrr: Add mtrr_ops support for Xen mtrr
