Subject: [PATCH 3/3] KVM MMU: Take sp level into account when calculating quadran
Date: Thu, 22 Apr 2010 17:34:24 +0800 [thread overview]
Message-ID: <4BD01820.3050809@cn.fujitsu.com> (raw)
Take sp level into account when calculating quadrant, because only when
level == PT_PAGE_TABLE_LEVEL, quadrant is needed.
