From 1afd0f6f17db1625a50b69a1edc40f5163db7c31 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Thu, 16 Feb 2017 01:20:18 +0000 Subject: [PATCH] sunxi: fix ACTLR.SMP assembly routine If we take the liberty to use register r0 to perform our bit set, we should be nice enough to tell the compiler about it. Add r0 to the clobber list to avoid potential mayhem.
