Subject: [PATCH 9/9] drm/i915: use stolen_usable_size for the range sanity check
Date: Tue,  5 Dec 2017 21:02:49 +0000	[thread overview]
Message-ID: <20171205210249.8875-10-matthew.auld@intel.com> (raw)
In-Reply-To: <20171205210249.8875-1-matthew.auld@intel.com>

In i915_pages_create_for_stolen it probably makes more sense to check if
the range overflows the stolen_usable_size, since stolen_size will
also include the reserved portion which we can't touch.
