[GIT PULL] VFIO fixes for v6.18-rc6

[Alex Williamson]

Hi Linus,

Here are a few last fixes for the new vfio selftests for v6.18.  This
hopefully starts us off with a good precedent that the tests will
generally pass by removing some assumptions about the IOMMU address
width.  Thanks,

Alex

  vfio: selftests: replace iova=vaddr with allocated iovas (2025-11-12 08:04:42 -0700)

VFIO fixes for v6.18-rc6

 - Fix vfio selftests to remove the expectation that the IOMMU
   supports a 64-bit IOVA space.  These manifest both in the original
   set of tests introduced this development cycle in identity mapping
   the IOVA to buffer virtual address space, as well as the more
   recent boundary testing.  Implement facilities for collecting the
   valid IOVA ranges from the backend, implement a simple IOVA
   allocator, and use the information for determining extents.
