[PATCH 0/2] fixed dump_backtrace() when task running on another cpu

[Wang Qing]

We cannot get FP and PC when the task is running on another CPU,
task->thread.cpu_context is the last time the task was switched out,
it's better to give a reminder than to provide wrong information.

We have no interface whether the task is running,
so we need to add an interface and distinguish CONFIG_SMP.
