[GIT PULL] workqueue changes for 4.1-rc1

[Tejun Heo]

Hello, Linus.

Workqueue now prints debug information at the end of sysrq-t which
should be helpful when tracking down suspected workqueue stalls.  It
only prints out the ones with something currently going on so it
shouldn't add much output in most cases.

Thanks.
