The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below.
expression e1, e2;
@@
- pci_set_dma_mask(e1, e2)
+ dma_set_mask(&e1->dev, e2)
@@
expression e1, e2;
@@
- pci_set_consistent_dma_mask(e1, e2)
+ dma_set_coherent_mask(&e1->dev, e2)
While at it, some 'dma_set_mask()/dma_set_coherent_mask()' have been
updated to a much less verbose 'dma_set_mask_and_coherent()'.

The logic is reversed here. We used to have a !, but it is now missing.
