x86_64: Fail dma_alloc_coherent on dma less devices
This should fix an oops with PCMCIA PATA devices
http://bugzilla.kernel.org/show_bug.cgi?id=8424
This is not a full fix for the problem, but probably
still the right thing to do.
[ I'm almost certain it's *not* the right thing to do, but it avoids an
oops, and I want comments from others on what the right thing would
actually be.. I suspect we should just remove the use of dma_mask
entirely in this function, and just use coherent_dma_mask. - Linus ]
