To: kashyap.desai@...adcom.com, sumit.saxena@...adcom.com,
shivasharan.srikanteshwara@...adcom.com, jejb@...ux.ibm.com
Cc: megaraidlinux.pdl@...adcom.com, linux-scsi@...r.kernel.org,
linux-kernel@...r.kernel.org
Subject: [PATCH 2/2] scsi: megaraid: Remove remaining 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 has been hand modified to replace GFP_ with correct flags based on
the context.
Compile-tested.
