Subject: [RHEL5.1 patch][xen] increase limits to boot on large ia64 platforms
Date: Fri, 24 Aug 2007 14:42:17 -0400
Bugzilla: 254062
Message-Id: <1187980937.17138.24.camel@athlon>
Changelog: [xen] increase limits to boot on large ia64 platforms


Fix for BZ 254062

This patch is needed to increase some limits to account for large memory
maps on the larger HP ia64 systems for xen.  This only increases limits
and only on ia64, it does not make any functional changes.  Any
(unlikely) regressions would be found by simple boot testing.
