4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Helge Deller <deller@gmx.de>
commit 56188832a50f09998cb570ba3771a1d25c193c0e upstream.
Some machines can't power off the machine, so disable the lockup detectors to avoid this watchdog BUG to show up every few seconds: watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [systemd-shutdow:1]
