Subject: [PATCH 15/30] staging/vme_user: remove __iomem marking from kern_buf and derivates
Date: Fri, 22 Oct 2010 02:36:37 -0400 [thread overview]
Message-ID: <1287729412-24356-16-git-send-email-cota@braap.org> (raw)
In-Reply-To: <1287729412-24356-1-git-send-email-cota@braap.org>
From: Emilio G. Cota <cota@braap.org>
kern_buf is not iomem; it comes from kmalloc and is directly
dereferenced.
Signed-off-by: Emilio G. Cota <cota@braap.org>
