[Venkatesh Pallipadi]

Yes. Patch below should fix the problem.

Fix below warning -
 Introduced by commit abb74cefa9c682fb38ba86c17ca3c86fed6cc464 ("sched:
 Export ns irqtimes through /proc/stat").

After merging the tip tree, today's linux-next build (powerpc
ppc64_defconfig) produced these warnings:

kernel/sched.c:3719: warning: 'irqtime_account_idle_ticks' defined but not =
used
kernel/sched.c:3720: warning: 'irqtime_account_process_tick' defined but no=
t used
