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) address review comments of last round
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
