[GIT PULL UPDATED] workqueue core changes for 3.9-rc1

[Tejun Heo]

Hello, again, Linus.

wq/for-3.8-fixes contained one commit to drop _GPL from
delayed_work_timer_fn() export (a regression which prevents
out-of-kernel users from using delayed_work) which didn't get pushed
out and I forgot to cherry pick it.

Everything else is the same other than one more commit at the top -
1438ade567 ("workqueue: un-GPL function delayed_work_timer_fn()").
