Okay, current situation on the Xen path is that it's all checked in except:
 * the changes to shutdown.c and smp.c
 * the bits that actually interface with sboot (that's most of the bits
inside CONFIG_TXT).

For the former, I'd like it to be a separate cleanup patch, with some
explanation of why it's required. For example, whay is the code movement in
smp.c required at all?

For the latter, I would like Xen to have its own asm-x86/sboot.h, even
though this causes a small amount of code duplication outside of th esboot
module itself. It is supposed to become a stable interface after all. The
bit syou need from uuid.h can also be included in Xen's sboot.h. All the
names you create in Xen's sboot.h should have a suitable common prefix on
them. I guess mle_ might do the trick, although I don't actually know what
MLE stands for?!

That's all for now. The sboot module itself is scary big. :-/

Oh, you can find the current tip to re-merge against at
