Subject: [PATCH 11 of 22 v2] xenpaging: do not bounce p2mt back to the hypervisor
Date: Mon, 20 Jun 2011 11:57:25 +0200 [thread overview]
Message-ID: <20110620095725.GA12615@aepfle.de> (raw)
In-Reply-To: <20110613104814.GC17634@whitby.uk.xensource.com>
do not bounce p2mt back to the hypervisor because p2m_mem_paging_populate()
and p2m_mem_paging_resume() dont make use of p2mt.
