[PATCH 12/12] x86_64: __clear_user as case of __memset_user

To avoid code duplication, re-use __memset_user(), when clearing user-space memory. The overhead should be minimal (2 extra register assignments) and outside of the writing loop. Signed-off-by: Igor Stoppa CC: Andy Lutomirski CC: Nadav Amit CC: Matthew Wilcox CC: Peter Zijlstra CC: Kees
