Thanks.

Yes, I intend to apply 1-5 to xen-unstable.hg now unless someone
shouts to tell me not to.

Does 8 depend on 6 and 7 ?

Thanks.  Bear in mind that we are in at the end of the release cycle
now and the tree is becoming more and more frozen.

Since xenpaging doesn't work properly without your patches they're
bugfixes but we do want to get all of them in sooner rather than
later.  It's possible that we'll have to release without all the
changes you might want to make :-/.

Thanks,
Ian.
