[PATCH 1/4] x86 paravirt_ops: create no_paravirt.h for native ops
(Andrew, please sit these in the -mm tree for cooking)
Create a paravirt.h header for (almost) all the critical operations
which need to be replaced with hypervisor calls.
For the moment, this simply includes no_paravirt.h, where all the
native implementations now live.

[PATCH 1/3] Paravirtualization: Kernel Ring Cleanups
Hi all,
I've been looking at finding common ground between the VMI, Xen and
other paravirtualization approaches, and after some discussion, we're
getting somewhere.
These first two patches are the fundamentals, stolen mainly from the
VMI patches: removing assumptions about the kernel running in ring 0,
and macro-izing all the obvious para-virtualize-needing insns. The
third patch is

[PATCH] paravirt.h
This version over last version:
(1) Gets rid of the no_paravirt.h header and leaves native ops in place
(with some reshuffling to keep then under one #ifdef).
(2) Fixes the "X crashes with CONFIG_PARAVIRT=y" bug.
(3) Puts __ex_table entry in paravirt iret.
Another followup patch implements binary patching...

[RFC] First (incomplete) cut of Xen paravirt binding
I've updated the patches at
http://ozlabs.org/~rusty/paravirt/?mf=33ba6c4fce13;path=/ to carve out
the basic shape of how I see all this fitting together.
These patches implement an initial set of Xen paravirt ops, as well as
adapting head.S to set up a Xen-specific entrypoint. The head.S code
does absolutely minimal setup, and then calls xen_start_kernel(). This
installs the Xen
