[PATCH 0/5] lguest feedback tidyups
Hi all,
Gratefully-received recent feedback from CC'd was applied to excellent
effect (and the advice from Matt Mackall about my personal appearance is
best unrequited).
The patch is split in 5 parts to correspond with the 9 parts Andrew
sent out before, but here's the summary:
1) Sparse (thanks Christoph Hellwig):
- lguest_const can be static now
- lguest.c should include

[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.
