From 5a97d0ae5b5d78727b87965cba84194a9f1e06ce Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 3 Feb 2012 11:08:05 +0100 Subject: ARM: 7314/1: kuser: consistently use usr_ret for returning from helpers __kuser_cmpxchg64 has a return path using bx lr to get back to the caller. This is actually ok since the code in question is predicated on CONFIG_CPU_32v6K, but for the sake of consistency using the usr_ret macro is probably better.
