From 2e2cfbe61b8e2cb1339e456ba764c0bd7c913a6e Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Fri, 15 Nov 2013 11:56:49 +1000 Subject: [PATCH] drm/nouveau/vm: reduce number of entry-points to vm_map() Pretty much everywhere had to make the decision which to use, so it makes a lot more sense to just have one entrypoint decide the path to take instead.
