At this point, nothing's etched in stone, as I'm really just scratching
the xen surface.  I don't want to explicitly include xenctrl.h given that
the vast majority of crash users then wouldn't be able to build new
versions of crash.  Not to mention that xenctrl.h in turn includes a
bunch of other xen-specific header files as well.  And all I really need
is the dumpfile header.

Probably...

Don't really have one -- the prime function in keeping the crash utility
alive is to keep up with kernel data-structure changes that break
dependencies that crash has.

That being said, the whole xen support issue is a major "TODO", and right now
I'm just trying to lay down a workable framework, first for x86 domU kernels
with writable page tables.  Then with that in place, the same process can
be used for x86-PAE, then kernels with shadow page tables, then x86_64,
ia64, VMX-enable kernels, and so on.  Anyway, once getting the basic
framework in place, any help getting the remaining pieces in place will be
gratefully accepted.  But the pieces in 4.0-2.22 are proof of concept in nature,
and subject to change.  So stay tuned...

Thanks,
   Dave
