Thomas Gleixner ae99286b4f nohz: disable tick_nohz_kick_tick() for now
Impact: nohz powersavings and wakeup regression

commit fb02fbc14d (NOHZ: restart tick
device from irq_enter()) causes a serious wakeup regression.

While the patch is correct it does not take into account that spurious
wakeups happen on x86. A fix for this issue is available, but we just
revert to the .27 behaviour and let long running softirqs screw
themself.

Disable it for now.
