I still think that it has some value, so taking up the mantle.

Motivation:
Allow lazy mode be default mode for DMA domains for all ARCHs, and not
only those who hardcode it (to be lazy). For ARM64, currently we must use
a kernel command line parameter to use lazy mode, which is less than
ideal.

I have now included the print for strict/lazy mode, which I originally
sent in:
https://lore.kernel.org/linux-iommu/72eb3de9-1d1c-ae46-c5a9-95f26525d435@huawei.com/ (local)

There was some concern there about drivers and their custom prints
conflicting with the print in that patch, but I think that it
should be ok.

Based on next-20210611 + "iommu: Update "iommu.strict" documentation"

Hi Joerg, Will,

We think that this series is ready to go.

There would be a build conflict with the following:
https://lore.kernel.org/linux-iommu/20210616100500.174507-1-namit@vmware.com/ (local)

So please let us know where you stand on it, so that could be resolved.

Robin and Baolu have kindly reviewed all the patches, apart from the AMD 
one.

Thanks,
John
