Subject: [PATCH 04/17] x86: Use new cache mode type in drivers/video/fbdev/vermilion
Date: Fri, 31 Oct 2014 15:00:20 +0100	[thread overview]
Message-ID: <1414764033-30011-5-git-send-email-jgross@suse.com> (raw)
In-Reply-To: <1414764033-30011-1-git-send-email-jgross@suse.com>

Instead of directly using the cache mode bits in the pte switch to
using the cache mode type.
