4.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Helge Deller <deller@gmx.de> commit 92420bd0d01f040bbf754e1d090be49ca6a1c8d6 upstream. The config option HAVE_UNSTABLE_SCHED_CLOCK is set automatically when compiling for SMP. There is no need to clear the stable-clock flag via clear_sched_clock_stable() when starting secondary CPUs, and even worse, clearing it triggers wrong self-detected CPU stall warnings on 64bit Mako machines.
