Hmm, VM_DMA would become generic flag? AFAIU, maybe VM_DMA would be used only on ARM arch.
Right now yes, it will be used only on ARM architecture, but maybe other architecture will start using it once it is available.
There's very little about the code in question that is ARM-specific to begin with. I plan to adopt similar changes on SH once the work has settled one way or the other, so we'll probably use the VMA flag there, too.
I don't think VM_DMA is good idea because x86_64 has two dma zones. x86 unaware patches make no sense.
