From cda7e4137a4e39c7d877b6ed41da13a5b30dd2cf Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Wed, 23 Apr 2014 20:06:20 +0200 Subject: [PATCH] arc: 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.
