However the prototype for it is within HAVE_UNSTABLE_SCHED_CLOCK ifdef/endif. That, combined with this: arch/parisc/Kconfig: select HAVE_UNSTABLE_SCHED_CLOCK if SMP means that parisc can have it either enabled or disabled, resulting in the following build fail: arch/parisc/kernel/setup.c:180:2: error: implicit declaration of function 'clear_sched_clock_stable' [-Werror=implicit-function-declaration] Add a no-op stub for the non-SMP case to prevent this.
