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.
