Subject: [PATCH 5/5] xen: reserve Xen start_info rather than e820 reserving
Date: Thu, 07 May 2009 11:56:49 -0700 [thread overview]
Message-ID: <4A032EF1.6070708@goop.org> (raw)
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.
