From 68005b67d15a1ee5b5ddff965175728e65fa73e7 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 13 Feb 2019 08:01:30 +0100 Subject: powerpc/dma: use the generic direct mapping bypass Now that we've switched all the powerpc nommu and swiotlb methods to use the generic dma_direct_* calls we can remove these ops vectors entirely and rely on the common direct mapping bypass that avoids indirect function calls entirely. This also allows to remove a whole lot of boilerplate code related to setting up these operations.
