Subject: [Patch Part2 V1 02/14] iommu/vt-d: move private structures and variables into intel-iommu.c
Date: Tue,  7 Jan 2014 17:00:22 +0800	[thread overview]
Message-ID: <1389085234-22296-3-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1389085234-22296-1-git-send-email-jiang.liu@linux.intel.com>

Move private structures and variables into intel-iommu.c, which will
help to simplify locking policy for hotplug. Also delete redundant
declarations.
