Version 1.0 beta2 (bugfix)

Changelog:

- avoid kernel crash (usually a oops in smp.c) by checking if a core is online before putting work on it: this problem appeared on opo qualcomm
  platform with proprietary mpdecision hotplugging service. assumption is that there is a delay between initiating hotplugging events from 'userland'
  and gathering core state info in 'kernel land' so under some rare circumestances the governor doesn't 'know about' a changed core state and tries to
  put work on a meanwhile offline core or that hotplug event happend during putting work on a core in the governor.
