Xuewen Yan 400a2ae671 epoll: Add synchronous wakeup support for ep_poll_callback ... commit 900bbaae67 upstream. Now, the epoll only use wake_up() interface to wake up task. However, sometimes, there are epoll users which want to use the synchronous wakeup flag to hint the scheduler, such as Android binder driver. So add a wake_up_sync() define, and use the wake_up_sync() when the sync is true in ep_poll_callback().
