From 131e663bd6f1055caaff128f9aa5071d227eeb72 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 9 Jul 2015 23:32:33 +0200 Subject: [PATCH] drm/gem: rip out drm vma accounting for gem mmaps Doesn't really add anything which can't be figured out through proc files. And more clearly separates the new gem mmap handling code from the old drm maps mmap handling code, which is surely a good thing.
