From b7271b9f3e18181559b96a610f4e42bdb04b07f5 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Wed, 22 Jun 2016 11:16:49 +0200 Subject: locking/atomic, arch/tile: Fix tilepro build The tilepro change wasn't ever compiled it seems (the 0day built bot also doesn't have a toolchain for it). Make it work. The thing that makes the patch bigger than desired is namespace collision with the C11 __atomic builtin functions. So rename the tilepro functions to __atomic32.
