[PATCH 00/04] Kexec / Kdump: Release 20061130 (xen-unstable-12621)

Hi again,

Here comes yet another release of the Kexec / Kdump patches for x86 Xen.
Many thanks to Ian Campbell for reviewing the previous version of the
patch set, I hopefully managed to fix all issues reported. I've spent 
the day so far up-porting and testing as you can see below. The results
are all good, and I think the code is in a good condition.

If there is anything I can do to help out with the merge don't hesitate
to ask!
