[PATCH 19/20] mips: smp: fix setup_profiling_timer() prototype

From: Arnd Bergmann
Date: Mon Dec 04 2023 - 06:59:45 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

The function is unconditionally defined in smp.c but is conditionally
declared in a header that is not included here.

arch/mips/kernel/smp.c:473:5: error: no previous prototype for 'setup_profiling_timer' [-Werror=missing-prototypes]

Add the missing #include and #ifdef to match the declaration.
