From 5cc494972adbaeff08a1b7544acaa608c68cd527 Mon Sep 17 00:00:00 2001 From: Markos Chandras Date: Thu, 2 Jan 2014 15:55:58 +0000 Subject: MIPS: lib: strlen_user: Use macro to build the strlen_user symbol Build the __strlen_user symbol using a macro. In EVA mode we will need to use similar code to do the userspace load operations so it is better if we use a macro to avoid code duplications.
