From e182c570e9953859aee5cb016583217d9e68ea18 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Fri, 12 Dec 2014 01:56:04 +0200 Subject: x86/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.
