The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below.
It has been compile tested.

If needed, see post from Christoph Hellwig on the kernel-janitors ML:
https://marc.info/?l=kernel-janitors&m=158745678307186&w=4
It is *NOT* been compile tested, but it looks safe enough!
