From 9eaa9a82e5d6be2234482c3468ed56143c713729 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Mon, 17 Oct 2016 15:34:37 +0100 Subject: [PATCH] MIPS: Allow pre-r6 emulation on SMP MIPSr6 kernels There's no reason for the pre-r6 instruction emulation code to be limited to uniprocessor kernels. We already emulate atomic memory access instructions in a way that works for SMP systems, and nothing else should be affected. Remove the artificial limitation, allowing pre-r6 instruction emulation to be used with SMP kernels.
