Does ia64 Windows generate a dump if you send it an NMI? That would be a
more generic mechanism that would allow x86 HVM to share the same domctl or
hvm_op. Otherwise we need a send_init hypercall for ia64 and a send_nmi
hypercall for x86, or we need a more vague generic name like
"trigger_dump_switch" (which actually is rather attractive now I think about
it).
