Test Description:
-------
# ==== switcher_
# when switcher is disabled in run time, we can get cpu2, cpu3 and cpu4 also online
# total we can see 5 cpus online. this test will hot-plug cpus 1,2,3 and 4.
# hot-plug cpus randomly one after other for 100 loops on each four different ways.
# ensure there would not be any kernel crash
# enable back the switcher after test
