v4:

• Separate HWPT alloc/destroy/abort functions between user-managed HWPTs and kernel-managed HWPTs
• Rework invalidate uAPI to be a multi-request array-based design
• Add a struct iommu_user_data_array and a helper for driver to sanitize and copy the entry data from user space invalidation array
• Add a patch fixing TEST_LENGTH() in selftest program
• Drop IOMMU_RESV_IOVA_RANGES patches
• Update kdoc and inline comments
• Drop the code to add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation, this does not change the rule that resv regions should only be added to the kernel-managed HWPT. The IOMMU_RESV_SW_MSI stuff will be added in later series as it is needed only by SMMU so far.

This doesn't apply to iommufd next so you will have to resend it

sure. I'm working with Nic on a new version.
