[patch 00/21] Xen-paravirt: Xen guest implementation for paravirt_ops interface

Hi Andi,

This patch series implements the Linux Xen guest in terms of the
paravirt-ops interface.  The features in implemented this patch series
are:
 * domU only
 * UP only (most code is SMP-safe, but there's no way to create a new vcpu)
 * writable pagetables, with late pinning/early unpinning
   (no shadow pagetable support)
 * supports both PAE and non-PAE modes
 * xen console
 * virtual block device (blockfront)
 * virtual network device (netfront)

The patch series is in two parts:

1-12: cleanups to the core kernel, either to fix outright problems,
      or to add appropriate hooks for Xen
13-21: the Xen guest implementation itself

I've tried to make each patch as self-explanatory as possible.  The
series is based on 2.6.20 + Andi Kleen's firstfloor patches, specifically:
	page-allocation-hooks-for-vmi-backend
	paravirt-cpu-batching.patch
	iopl-handling-for-paravirt-guests
	smp-boot-hook-for-paravirt
	vmi-backend-for-paravirt-ops
	vmi-timer

Changes since the previous posting:
- made vga not crash when vga hardware isn't present
- cleaned up sign issues in xen-console
- cleaned up mm-lifetime hooks
- blockfront cleanups
- other stuff

Thanks,
	J
