The legacy API wrappers in include/linux/pci-dma-compat.h
should go away as it creates unnecessary midlayering for
include/linux/dma-mapping.h APIs.
Instead use dma-mapping.h APIs directly.
The patch has been generated with the coccinelle script below.
Compile-tested.

The legacy API wrappers in include/linux/pci-dma-compat.h
should go away as it creates unnecessary midlayering
for include/linux/dma-mapping.h APIs.
Instead use dma-mapping.h APIs directly.
The patch has been generated with the coccinelle script below.
And has been hand modified to replace each GFP_ with the correct
flag depending upon the context.
Compile-tested.

should go away as it creates unnecessary midlayering
for include/linux/dma-mapping.h APIs.
Instead use dma-mapping.h APIs directly.
The patch has been generated with the coccinelle script below.
And has been hand modified to replace each GFP_ with a correct
flag depending upon the context.
