Series of patchs to simplify policy/sysfs/kobj/locking handling across suspend/resume
The following have been tested so far on a 2x2 cluster environment: - Boot with 2 cpus and no cpufreq driver. - mod probe driver and see cpufreq sysfs files show up only for the 1st cluster. - Online the rest of the 2 CPUs and have files show up correctly. - rmmod the driver and see the files go away. - modprobe again (or back and forth multiples times) and see it work. - suspend/resume works as expected. - When a cluster is offline, all read/writes to its sysfs files return an error
