Subject: arm: dma-mapping.h
From: "Gary Zambrano" <zambrano@broadcom.com>

Added dma_sync_single_range_for_cpu/device to dma-mapping.h in asm-arm to call
dma_sync_single_for_cpu/device.  This patch enables b44 to compile on systems
with these cpus.  This patch was created with the assumption that another
method of dma_sync_single_range_for_cpu/device does not exist on these
architectures.
