Message-ID: <1418575877-21488-8-git-send-email-mst@redhat.com> Date: Sun, 14 Dec 2014 18:52:27 +0200 From: "Michael S. Tsirkin" <mst@...hat.com> To: linux-kernel@...r.kernel.org Cc: Arnd Bergmann <arnd@...db.de>, linux-arch@...r.kernel.org, Tony Luck <tony.luck@...el.com>, Fenghua Yu <fenghua.yu@...el.com>, linux-ia64@...r.kernel.org Subject: [PATCH 07/18] ia64/uaccess: fix sparse errors virtio wants to read bitwise types from userspace using get_user. At the moment this triggers sparse errors, since the value is passed through an integer. Fix that up using __force. Signed-off-by: Michael S.
