Which had to be reverted b/c they caused regressions with
32-bit guests during migration. But Greg if you are just looking
to do it on a guest without migration then cherrypicking
 9d02b43dee0d7fb18dfb13a00915550b1a3daa9f
("xen PVonHVM: use E820_Reserved area for shared_info")
should do it for it.

Olaf, you wouldn't have any time to look at this some more now
that Xen 4.3 is out?
