Message-ID: <1420558883-10131-6-git-send-email-mst@redhat.com> Date: Tue, 6 Jan 2015 17:43:47 +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, Steven Miao <realmz6@...il.com>, adi-buildroot-devel@...ts.sourceforge.net Subject: [PATCH v2 05/40] blackfin/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.
