[PATCH 4.9 029/152] metag/usercopy: Drop unused macros
From: Greg Kroah-Hartman
Date: Mon Apr 10 2017 - 13:38:48 EST
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: James Hogan <james.hogan@xxxxxxxxxx>
commit ef62a2d81f73d9cddef14bc3d9097a57010d551c upstream.
Metag's lib/usercopy.c has a bunch of copy_from_user macros for larger
copies between 5 and 16 bytes which are completely unused. Before fixing
zeroing lets drop these macros so there is less to fix.
