This patch provides (or at least provided) SVM similar functionality to
what VMX has by allowing source-level debugging of unmodified guests.

I did my development and testing against changeset 11131 and all worked
fine.  However, recent changesets have broken gdbserver-xen's memory
read/write interface with the guest --- at least with respect to SVM
guests.  I haven't examined the problem too closely yet, but I think
this is a side effect from the shadow2 merge.

Anyway, if acceptable, please apply to -unstable.  I'm going to look
at the libxc/ptrace code a little more closely to see if I can root
cause the problem.

The patch doesn't apply to unstable tip, so let's leave this until you've
resolved the issues and post a fully working patch.

OK.  I'll try a working updated patch out.

BTW, Have you heard any reports that this feature has stopped working on
the VT side?
