Ingo Molnar 6498ddad30 softirq: Consolidate common code in __tasklet_[hi]_schedule() 
__tasklet_schedule() and __tasklet_hi_schedule() are almost identical.
Move the common code from both function into __tasklet_schedule_common()
and let both functions invoke it with different arguments.

[ bigeasy: Splitted out from RT's "tasklet: Prevent tasklets from going
  	   into infinite spin in RT" and added commit message. Use
  	   this_cpu_ptr(headp) in __tasklet_schedule_common() as suggested
  	   by Julia Cartwright ]
