No because upstream this is ignored. This is an incremental patch
on top of Jason's one.

I hope I made it clear that there are no such users.

[PATCH V2 RFC] fixup! virtio: convert to use DMA api
..._IOMMU_PLATFORM, false)
Looks like the impact of this patch is that users who relied on
k->get_dma_as today may now have to explicitly add iommu_platform=on.
Are there any such users (e.g. Xen)?
Instead of breaking the command-line for these users you could invert
the flag's meaning ("iommu_bypass=on") and set it in the SPARC/PPC
machine types.
