[GIT PULL] workqueue changes for v3.16-rc1

[Tejun Heo]

Hello, Linus.

Lai simplified worker destruction path and internal workqueue locking
and there are some other minor changes.  Except for the removal of
some long-deprecated interfaces which haven't had any in-kernel user
for quite a while, there shouldn't be any difference to workqueue
users.

Thanks.
