I'm not a fan of "nommu". Some of the users of direct ops *are* using an
IOMMU, they're just setting up a 1:1 mapping once at init time, rather
than mapping dynamically.
Though I don't have a good idea for a better name, maybe "1to1",
"linear", "premapped" ?
It seems like a nice counter part to the dma_iommu_ops used just about
anywhere else in ppc.
But I'll happily take any maintainer bike shed decision for the next
series. Remember that in a merge window or two it will hopefully
go away in favor of the new generic dma_direct ops.
