While testing, I found that we need to correct some of the dummy declarations. When I send my pull request to Linus, I wish to squash these changes into the original patches from Daniel. Could you please review?
Best regards,

=========
Dummy functions for the newly added cpu access ops are needed for compilation
when dma-buf framework is not compiled-in.
Also, the introduction of flags in dma_buf_fd needs to be added to dummy
functions as well.

Sorry for fumbling the compile-testing for the !DMA_BUF case here.
Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch>
