[RFC 01/11] sched: introduce sys_cpumask in tsk to adapt asymmetric system

Some system such as powerpc, some tsk (vcpu thread) can only run on the dedicated cpu. Since we adapt some asymmetric method to monitor the whole physical cpu. (powerKVM only allows the primary hwthread to set up runtime env for the secondary when entering guest). Nowadays, powerKVM run with all t
