From 66cbff59a16017234ea6c80ecddfc17b27a83504 Mon Sep 17 00:00:00 2001 From: Lai Jiangshan <laijs@cn.fujitsu.com> Date: Sat, 17 Apr 2010 17:00:19 +0800 Subject: KVM: do not call hardware_disable() on CPU_UP_CANCELED When CPU_UP_CANCELED, hardware_enable() has not been called at the CPU which is going up because raw_notifier_call_chain(CPU_ONLINE) has not been called for this cpu. Drop the handling for CPU_UP_CANCELED.
