From 18e900185b3ad75a04ee70ea291f71540e5f80e6 Mon Sep 17 00:00:00 2001 From: Leonid Yegoshin Date: Tue, 17 Dec 2013 15:20:24 +0000 Subject: MIPS: asm: uaccess: Disable unaligned access macros for EVA ulb, ulh, ulw are macros which emulate unaligned access for MIPS. However, no such macros exist for EVA mode, so the only way to do EVA unaligned accesses is in the ADE exception handler. As a result of which, disable these macros for EVA.
