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 ] Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
