[Patch Part1 V2 00/20] Bugfixes and improvements for Intel IOMMU drivers

[Jiang Liu <jiang.liu@linux.intel.com>]

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!

V2->V3:
1) Add three more patches 18, 19, 20
2) Fix minor bugs in previous version

V1->V2:
1) drop one wrong bugfix of " fix remapping interrupt handle leakage in
 error recovery path"
2) Kill redundant call of bitmap_allocate_region().
3) Add two new bugfixes.
