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

Pulled, thanks Will.
Pushing might take some time, as I temprarily lost access to my
compile-test machine.
Regards,
Joerg

I can see 'em in linux-next now, so looks like it worked out.
Thanks!
