[GIT PULL] iommu/arm-smmu: Updates for 6.10

[Will Deacon]

Hi Joerg,

Please can you pull these Arm SMMU updates for 6.10? Similarly to last
time, we have quite a lot here mainly thanks to Jason's ongoing rework
of the SMMUv3 driver in pursuit of full support for IOMMUFD.

Summary in the tag.

Cheers,

Will

  iommu/arm-smmu-v3: Add unit tests for arm_smmu_write_entry (2024-05-01 15:33:53 +0100)

----------------------------------------------------------------
Arm SMMU updates for 6.10

- SMMUv2:
  * Support for fault debugging hardware on Qualcomm implementations
  * Re-land support for the ->domain_alloc_paging() callback

- SMMUv3:
  * Improve handling of MSI allocation failure
  * Drop support for the "disable_bypass" cmdline option
  * Major rework of the CD creation code, following on directly from the
    STE rework merged last time around.
  * Add unit tests for the new STE/CD manipulation logic
