[PATCH 1/2] lguest: fix up after pda->percpu conversion
Andrew Morton commented out some stuff to make lguest compile. This
should actually make it work (in the latest -mm).

[PATCH 0/8] lguest
As promised to Andrew, and with much thanks to Andi Kleen for feedback,
this is the new series of lguest patches.
Main change is the move to drivers/lguest (for future non-i386
expansion), but lots of cleanups driven by Andi's feedback and the
documentation effort (which made me examine every line of code).
It's not perfect, but it's definitely useful.
Cheers,
Rusty.

[PATCH 00/12] xen/paravirt_ops patches for 2.6.24
Hi Linus,
Here's a set of patches to update paravirt_ops and Xen for 2.6.24
A quick overview of the patchset:
paravirt_ops:
Remove the monolithic paravirt_ops structure, and replace it with
smaller structures of related functions. Also, clean up the handling
of lazy mode to make it easier to implement.
x86/mm/init.c: remove a chunk of dead code
Xen:
- remove duplicate includes

[PATCH 0/7] Modify lguest32 to make room for lguest64
Hi all,
I've been working on lguest64 and in order to do this, I had to move
a lot of the i386 specific out of the way. Well, the lguest64 port
is still not ready to display, but before Rusty makes too many changes
I would like this in upstream so I don't have to keep repeating my
changes :-)
So this patch series moves lguest32 out of the way for other archs.

Changes since last version.
- Move lg.h to include/asm instead (suggested by Rusty Russel)

[patch 00/43] lguest: Patches for 2.6.24 (and patchbomb test)
Hi all,
These are the patches I'm planning to submit for 2.6.24. Comments
gratefully accepted. Along with the usual cleanups and improvements are Jes'
de-i386-ification patches, and a new "virtio" mechanism designed to be shared
with KVM (and hopefully other hypervisors).
Cheers,
Rusty.
