[PATCH 1/3] Documentation and example updates
1) Example code: old libc headers don't have SIOCBRADDIF, and old zlibs
don't have gzdirect() -- it's a sanity check anyway.
2) Some people don't build in their source directories, so .config
isn't there (thanks to Tony Breeds <tony@bakeyournoodle.com>).
3) Point out that guest and host kernel are usually the same.
4) Set the "no checksum" option on the

[PATCH 0/2 v05] lguest: TSC & hrtimers
The following patches are the latest update of the TSC and hrtimer patches
I posted on 29/03.
Rusty's original TSC patch has been resynced to the latest lguest repo,
as has the hrtimer patch, which also incorporates feedback from Jeremy &
Rusty:
- Change clock event hrtimer to absolute time. 'now' is captured in the
host during the hypercall.

[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 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.
