Subject: [PATCH 2/4] drm/ttm: rework handling of private mem types
Date: Mon, 12 Sep 2016 13:46:42 +0200	[thread overview]
Message-ID: <1473680804-23037-2-git-send-email-deathsimple@vodafone.de> (raw)
In-Reply-To: <1473680804-23037-1-git-send-email-deathsimple@vodafone.de>

From: Christian König <christian.koenig@amd.com>

Instead of keeping a bunch of potentially unused flags, just define
the start for private memory types and remove the rest.
