I'm not sure how this is relevant to anything.
What we're talking about is how to get from Xen to a point in the
Linux kernel where everything can Just Work. The proposed feature is
a mini trampoline that (as I understand it):
1. Tells Xen where to jump to (via ELF note)
2. Sets up some basic modes and pagetables and then jumps to the zero
page so Linux can just carry on.
