[PATCH 1/3] lguest: speed up PARAVIRT_LAZY_FLUSH handling
When Zach Amsden added PARAVIRT_LAZY_FLUSH I didn't realize how often
it would get called. We only need to do something if we're actually
in lazy mode.
Before:
Time for one context switch via pipe: 10509 (9863 - 18761)
Time for one Copy-on-Write fault: 71796 (20625 - 207750)
Time to exec client once: 1076218 (1066203 - 1085937)
Time for one fork/exit/wait: 1193125 (574750 - 1197750)

[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 1/7] lguest: documentation pt I: Preparation
The netfilter code had very good documentation: the Netfilter Hacking
HOWTO. Noone ever read it.
So this time I'm trying something different, using a bit of
Knuthiness. Start with drivers/lguest/README.

[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.
