Hi Joerg,
Please pull these Arm SMMU updates for 5.15. There's not tonnes here, but
a good mixture of optimisations and cleanups -- summary in the tag.
This applies cleanly against iommu/next, but I suspect it will conflict
with Robin's series on the list. Please shout if you need anything from
me to help with that (e.g. rebase, checking a merge conflict).
Cheers,
Will

In fact it merges cleanly into my local branch, so I hope we should be
good :)

For now there were at least no conflicts which git couldn't resolve
automatically, but the compile tests are still running :)

So this is pulled now, thanks.

Compile tests went fine and the kernel booted fine on my workstation, so
I pushed things out. Let's see whether testing in linux-next breaks
anything.
