[Xen-devel] [PATCH 8/8] xen: reserve Xen start_info rather than e820 res
From: Jeremy Fitzhardinge <jeremy.fitzhardinge@xxxxxxxxxx>
Use reserve_early rather than e820 reservations for Xen start info and mfn->pfn
table, so that the memory use is a bit more self-documenting.
Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@xxxxxxxxxx>
