Subject: Re: [PATCH] xen: release all pages within 1-1 p2m mappings
Date: Thu, 29 Sep 2011 12:29:09 +0100	[thread overview]

Er. This was the wrong patch.  I meant to repost "xen: allow extra
memory to be in multiple regions" to remove unnecessary test of
E820_UNUSABLE in xen_align_and_add_e820_region().

Sorry.

David
