2016-12-30drm/armada: Fix compile failDaniel Vetter1-0/+2
I reported the include issue for tracepoints a while ago, but nothing seems to have happened. Now it bit us, since the drm_mm_print conversion was broken for armada. Fix it, so I can re-enable armada in the drm-misc build configs. v2: Rebase just the compile fix on top of Chris' build fix.

2016-12-27drm: kselftest for drm_mm and alignmentChris Wilson2-0/+106
Check that we can request alignment to any power-of-two or prime using a plain drm_mm_node_insert(), and also handle a reasonable selection of primes. v2: Exercise all allocation flags Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20161222083641.2691-14-chris@chris-wilson.co.uk
2016-12-27drm: kselftest for drm_mm_insert_node_in_range()Chris Wilson2-0/+270
Exercise drm_mm_insert_node_in_range(), check that we only allocate from the specified range. v2: Use all allocation flags v3: Don't pass in invalid ranges - these will be asserted later.

2016-12-27drm: kselftest for drm_mm_replace_node()Chris Wilson2-6/+60
Reuse drm_mm_insert_node() with a temporary node to exercise drm_mm_replace_node(). We use the previous test in order to exercise the various lists following replacement. v2: Check that we copy across the important (user) details of the node. The internal details (such as lists and hole tracking) we hope to detect errors by exercise.
