To remove common users of xen_regs/execution_context_t (i.e.
drivers/char/*.c) I think we should be able to just pass 'current' to
show_registers().

To remove full_execution_context_t, we'll need to change the
arch_getdomaininfo_ctxt() interface a little bit (to do the copy
itself), then add a arch hook for do_boot_vcpu() and set_info_guest().
Right?

Sounds like that would help clean up ia64 code a bit, so let's do it. :)

Even after that's done though, I see value in having core structures
like these named identically across architectures. I understand now that
some of those won't matter to you... but at least
exec_domain/arch_exec_domain still should, and we're also talking about
those names.
