take use of VCPU_NOTIFY vector, add smp_call_function support. added a per_cpu field smp_call_info, and make each smp_call_function is not re-entered, and the caller CPU is returned when all the target CPUs complete the call. v4: - remove global lock - take use of wait_sync_change function to do the sequence sync v3: - remove per_cpu lock in smp_call_info - use a global lock to ensure smp_call_function sequence - use pcpu_sync_sleep to wait IPI complete v2: - after new smp function come, if old one exist, changed from overwirte with the new one to ignore the new one.
