Message-Id: <1342462680-18548-1-git-send-email-ccross@android.com> Date: Mon, 16 Jul 2012 11:18:00 -0700 From: Colin Cross <ccross@...roid.com> To: linux-arm-kernel@...ts.infradead.org Cc: Catalin Marinas <Catalin.Marinas@....com>, Will Deacon <will.deacon@....com>, Nicolas Pitre <nicolas.pitre@...aro.org>, Colin Cross <ccross@...roid.com>, Russell King <linux@....linux.org.uk>, linux-kernel@...r.kernel.org Subject: [PATCH] ARM: vfp: only clear vfp state for current cpu in vfp_pm_suspend 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.
