powerpc/smp: Move setup_profiling_timer() under CONFIG_PROFILING

mpe · mpe · commit a4ac0d249a5d · 2021-11-29T22:49:23.000+11:00
setup_profiling_timer() is only needed when CONFIG_PROFILING is enabled. Fixes the following W=1 warning when CONFIG_PROFILING=n: linux/arch/powerpc/kernel/smp.c:1638:5: error: no previous prototype for ‘setup_profiling_timer’ Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20211124093254.1054750-5-mpe@ellerman.id.au
