Xen devel - Aug 2010 - [PATCH] check whether cpu is online in cpu idle control

We observed a 2.6.18.8 dom0 kernel crash when Xen has maxcpus < num of 
physical cores (maxcpus=4 for a 12-core system). It appeared that 
hypervisor doesn''t check whether CPU is online or not. This small patch
fixed the issue.
