The reason for this was that I wanted to make the entire
relocate_kernel code fit into a single 16k page because
I was worried that if more than one page was used
it might not be machine contiguous.

As you pointed out offline:

   "I understood.  The pages is allocated by kimage_alloc_pages() which
    calls xen_limit_pages_to_max_mfn() so that pages are guaranteed to
    be machine contiguous."

So I am fine with this change.
