Subject: [PATCH 4/7] drm/ttm: move the page_alignment into the BO
Date: Tue, 13 Apr 2021 15:52:45 +0200	[thread overview]
Message-ID: <20210413135248.1266-4-christian.koenig@amd.com> (raw)
In-Reply-To: <20210413135248.1266-1-christian.koenig@amd.com>

The alignment is a constant property and shouldn't change.
