Subject: [PATCH 0/4] Infiniband Subsystem: Remove pci-dma-compat wrapper APIs.

Hii Developers,

This patch series will replace all the legacy pci-dma-compat wrappers
with the dma-mapping APIs directly in the INFINIBAND Subsystem.

This task is done through a coccinelle script which is described in each commit
message.

The changes are compile tested.

Thanks,

Suraj Upadhyay.

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

Coccinelle is great for some things, but not
necessarily for these sorts of changes in an
completely automated way.

The dev_err messages also need to be changed
as the format string contains the old name.

Yes, I forgot to add it in the queue.

Thought it would be nice if the patch ("efa") would be in the chain.

Though I am sending a v2 for that patch following joe perches suggestion.

Hope this wasn't an annoyance.

Aside from Joe's notes it doesn't apply either:

Applying: RDMA/efa : Remove pci-dma-compat wrapper APIs
Using index info to reconstruct a base tree...
error: patch failed: drivers/infiniband/hw/efa/efa_main.c:405

It does not apply to blobs recorded in its index.

Try to avoid hand editing patches..
