From c25630381c6e093819d86d9618798db932cc2d90 Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Thu, 15 Jan 2015 23:41:54 +0100 Subject: ARM: 8285/1: remove ARMv3 user access code again This code was restored with commit 080fc66fb5 ("ARM: Bring back ARMv3 IO and user access code") because the RiscPC memory bus does not understand half-word load/stores. However only the IO code needed restoring since the alternative user access code contains no half-word accesses, is already used when CONFIG_PREEMPT is set and runs faster on a StrongARM.
