Subject: [GIT PULL] iommu/arm-smmu: Fixes for 6.8-rc

Hi Joerg,

Please can you pull these two Arm SMMU fixes for 6.8-rc? I appreciate
it's getting late in the cycle, but it took us a little while to fix the
SVA allocation problem properly. The summary is in the tag.

I'll send you my 6.9 queue next week and it will be based on these
fixes.

Cheers,

Will

Arm SMMU fixes for 6.8

- Fix CD allocation from atomic context when using SVA with SMMUv3

- Revert the conversion of SMMUv2 to domain_alloc_paging(), as it
  breaks the boot for Qualcomm MSM8996 devices
