From mboxrd@z Thu Jan 1 00:00:00 1970 From: mst@redhat.com (Michael S. Tsirkin) Date: Tue, 6 Jan 2015 17:43:40 +0200 Subject: [PATCH v2 03/40] arm64/uaccess: fix sparse errors In-Reply-To: <1420558883-10131-1-git-send-email-mst@redhat.com> References: <1420558883-10131-1-git-send-email-mst@redhat.com> Message-ID: <1420558883-10131-4-git-send-email-mst@redhat.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
