Hello, Linus.
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.
