Subject: [PATCH] sched/clock: Remove watchdog touching
Git-commit: 3067a33d5fec856bb297d58e7f03411d060ccdee
Patch-mainline: v4.13-rc1
References: bsc#1052904

Commit: 

  2bacec8c318c ("sched: touch softlockup watchdog after idling")

introduced the touch_softlockup_watchdog_sched() call without
justification and I feel sched_clock management is not the right
place, it should only be concerned with producing semi coherent time.

If this causes watchdog thingies, we can find a better place.
