From a2b63aa2f45314bea077275c6009ba00c83826a0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 22 May 2017 11:07:48 +0200 Subject: hexagon: remove arch-specific dma_supported implementation This implementation is simply bogus - hexagon only has a simple direct mapped DMA implementation and thus doesn't care about the address.
