Hi Linus,

Small pull request this cycle, there are several larger series near
completion on the list that will hopefully go next round.

Thanks,
Jason

  iommufd: Fix struct iommu_hwpt_pgfault init and padding (2025-01-21 13:55:49 -0400)

----------------------------------------------------------------
iommufd 6.14 merge window pull

No major functionality this cycle:

- iommufd part of the domain_alloc_paging_flags() conversion

- Move IOMMU_HWPT_FAULT_ID_VALID processing out of drivers

- Increase a timeout waiting for other threads to drop transient refcounts
  that syzkaller was hitting

- Fix a UBSAN hit in iova_bitmap due to shift out of bounds

- Add missing cleanup of fault events during FD shutdown, fixing a memory leak

- Improve the fault delivery flow to have a smaller locking critical
  region that does not include copy_to_user()

- Fix 32 bit ABI breakage due to missed implicit padding, and fix the
  stack memory leakage

----------------------------------------------------------------
