--------------------------------

We implement the function of qos smt expeller by this following
two points：
a) when online tasks and offline tasks are running on the same
physical cpu, online tasks will send ipi to expel offline tasks
on the smt sibling cpus.
b) when online tasks are running, the smt sibling cpus will not
allow offline tasks to be selected.
