[ 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 Signed-off-by: Linus Torvalds --- Reading git-diff-tree failed
