[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
