So far the only way that I know to make Linux<->Xen and Xen<->Linux
Linux kexec/kdump transitions work is to use this phys_efi technique.
I realise that it doesn't work on SN. But it does seem to me that
a solution that works on some platforms (e.g. Tiger) is better than
no solution at all.

I'm not planing to have kexec set this flag under you nose or anything
like that. But rather to allow people (who's platform's support it) to
use it.
