[PATCH v3 0/2] Simplify hotplug/suspend handling

[Saravana Kannan]

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

Saravana Kannan (2):
  cpufreq: Don't destroy/realloc policy/sysfs on hotplug/suspend
  cpufreq: Simplify and fix mutual exclusion with hotplug
