[Patch Part1 V3 00/20] Bugfixes and improvements for Intel IOMMU drivers

[Jiang Liu]

This patchset includes several bugfixes and code improvements for
Intel DMA remapping and interrupt remapping drivers. It's also a
preparation for Intel IOMMU device hotplug.

It applies to the latest mainstream kernel on top of
	commit 7e3528c3660a2e8602abc7858b0994d611f74bc3

It has been tested on Intel SandyBridge and Romley-4S platforms.

Thanks!
