Please pull from the following branch to receive fix for a deadlock which can happen between rescuers and stop_machine() while bringing down CPUs. The problem could be half-reliably reproduced by Thilo-Alexander while the system is entering suspend. The branch also contains another commit which documents workqueue debugging tricks. The pull will cause conflict against 25985edced (Fix common misspellings). The fixed misspelling unfortunately was in the comment which the fix replaces. The conflict can be resolved by simply taking the version from the fix commit. git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq.git fixes-2.6.39 Thank you.
