softirq: reduce latencies

This commit can reduce softirq latencies in some various network workloads.

34376a50fb1fa095b9d0636fa41ed2e73125f214
Fix lockup related to stop_machine being stuck in __do_softirq.

The commit 34376a50fb1f fix a bug introduced by commit c10d73671ad3
(softirq: reduce latencies).

They look applicable to stable-3.4, but need some adjustments to backport.
The following patches are the backports.

What do you think?

Thanks.
