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

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.

Jiang Liu (20):
  iommu/vt-d: use dedicated bitmap to track remapping entry allocation
    status
  iommu/vt-d: fix PCI device reference leakage on error recovery path
  iommu/vt-d: fix a race window in allocating domain ID for virtual
    machines
  iommu/vt-d: fix resource leakage on error recovery path in
    iommu_init_domains()
  iommu/vt-d, trivial: refine support of 64bit guest address
  iommu/vt-d, trivial: print correct domain id of static identity
    domain
  iommu/vt-d, trivial: check suitable flag in function
    detect_intel_iommu()
  iommu/vt-d, trivial: clean up unused code
  iommu/vt-d: mark internal functions as static
  iommu/vt-d, trivial: use defined macro instead of hardcoding
  iommu/vt-d, trivial: simplify code with existing macros
  iommu/vt-d: fix invalid memory access when freeing DMAR irq
  iommu/vt-d: keep shared resources when failed to initialize iommu
    devices
  iommu/vt-d: avoid double free in error recovery path
  iommu/vt-d: fix access after free issue in function free_dmar_iommu()
  iommu/vt-d: release invalidation queue when destroying IOMMU unit
  iommu/vt-d: fix wrong return value of dmar_table_init()
  iommu/vt-d, PCI, trivial: use dev_is_pci() instead of hardcoding
  iommu/vt-d, trivial: clean sparse warnings
  iommu/vt-d: free all resources if failed to initialize DMARs
