Subject: [PATCH 3/4] RDMA/qib: Remove pci-dma-compat wrapper APIs
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 compile-tested.
