No, I don't think that's what Al is proposing. The kernel-internal
interfaces we've put in place to make Xen work could be reused to do
some of the things you're talking about. In particular, a kernel
running under Xen has to be able to deal with non-contiguous physical
pages, and reusing the same pagetable hooks would allow a kexeced kernel
to run happily out of any random assortment of pages you manage to
allocate for it.
