[PATCH 1/2] paravirt.h header
OK, this is the revised paravirt.h (Andi has seen this before), then the
second is the binary patching stuff. More things get added to the
paravirt struct in future patches, but this basic stuff hasn't changed
for some time.
====
This patch does the dumbest possible replacement of paravirtualized
instructions: calls through a "paravirt_ops" structure. Currently
these are function

[PATCH 0/7] x86 paravirtualization infrastructure
The following patches introduce the core infrastructure needed to
paravirtualize the 32-bit x86 Linux kernel. This is done by moving
virtualization sensitive insn's or code paths to a function table,
paravirt_ops. This structure can be populated with hypervisor specific
calls or native stubs and currently support running on bare metal, VMI,
Xen, or Lhype. These patches apply to

[patch 00/17] paravirt_ops updates
Hi Andi,
This series of patches updates paravirt_ops in various ways. Some of the
changes are plain cleanups and improvements, and some add some interfaces
necessary for Xen.
The brief overview:
add-MAINTAINERS.patch - obvious
remove-CONFIG_DEBUG_PARAVIRT.patch - no longer needed
paravirt-nop.patch - mark nop operations consistently
paravirt-pte-accessors.patch - operations to pack/unpack

[patch 00/20] paravirt_ops updates
Hi Andi,
Here's a repost of the paravirt_ops update series I posted the other day.
Since then, I found a few potential bugs with patching clobbering,
cleaned up and documented paravirt.h and the patching machinery.
Overview:
add-MAINTAINERS.patch
obvious
remove-CONFIG_DEBUG_PARAVIRT.patch
No longer meaningful or needed.

[patch 00/26] Xen-paravirt_ops: Xen guest implementation for paravirt_ops interface
Hi Andi,
This patch series implements the Linux Xen guest as a paravirt_ops
backend. 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 hvc console (console=hvc0)
