From ea2ebaa71c978254c2a93bf561236aec8a167166 Mon Sep 17 00:00:00 2001 From: Colin Cross Date: Fri, 20 Jul 2012 02:03:43 +0100 Subject: ARM: 7476/1: vfp: only clear vfp state for current cpu in vfp_pm_suspend commit a84b895a2348f0dbff31b71ddf954f70a6cde368 upstream. vfp_pm_suspend runs on each cpu, only clear the hardware state pointer for the current cpu. Prevents a possible crash if one cpu clears the hw state pointer when another cpu has already checked if it is valid.
