These patches look much better.

Can you give some description of your Elf format? If we plan to use Elf for
save/restore as well, it would be nice to pick a format that is
generalisable to both cases. The use of program headers seems weird (since
there is no sensible 'virtual address' to specify, as the Xen core dump
format is not defined in the context of a simple single address space) and
is going to be no use for live migration where we need to be able to specify
GPFN-GMFN relationships on the fly, presumably in a custom section format.

Are there any tools to parse this new dump format, or will we have to wait
for the crash utility and xc_ptrace_core() to catch up?
