[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.

[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.
