The dmac_* functions are private to the ARM DMA API implementation, and should not be used by drivers. In order to discourage their use, remove their prototypes and macros from asm/*.h. We have to leave dmac_flush_range() behind as Exynos and MSM IOMMU code use these; once these sites are fixed, this can be moved also. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
