paravirt_alloc_pd_clone() useful?
Do you use paravirt_alloc_pd_clone()? I seem to you remember you
mentioning that it doesn't help you very much. I'm in the process of
unifying pgalloc*, and it seems to me that it would be a bit cleaner
without needing to worry about paravirt_alloc_pd_clone()...

[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

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:

No longer meaningful or needed.

[patch 00/20] XEN-paravirt: Xen guest implementation for paravirt_ops interface
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
