From 27782f2752aca65a241f10fb2d4508c71bb2656b Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Wed, 23 Apr 2014 19:51:36 +0200 Subject: [PATCH] mips: Provide atomic_{or,xor,and} Implement atomic logic ops -- atomic_{or,xor,and}. These will replace the atomic_{set,clear}_mask functions that are available on some archs.
