vfio: selftests: Drop includes

2025-12-23T21:17:13Z

Drop the includes now that (tools/include/linux/types.h) has a definition for __aligned_le64, which is needed by . Including is harmless but causes benign typedef redefinitions. This is not a problem for VFIO selftests but becomes an issue when the VFIO selftests library is built into KVM selftests, since they are built with -std=gnu99 which does not allow typedef redifitions.

vfio: selftests: Move IOMMU library code into iommu.c

2025-11-28T17:58:06Z

Move all the IOMMU related library code into their own file iommu.c. This provides a better separation between the vfio_pci_device helper code and the iommu code. No function change intended.
