From 384b38b66947b06999b3e39a596d4f2fb94f77e4 Mon Sep 17 00:00:00 2001 From: Yuanyuan Zhong Date: Wed, 30 Oct 2013 17:31:49 +0100 Subject: ARM: 7873/1: vfp: clear vfp_current_hw_state for dying cpu The CPU_DYING notifier is called by cpu stopper task which does not own the context held in the VFP hardware. Calling vfp_force_reload() has no effect. Replace it with clearing vfp_current_hw_state.
