[ Upstream commit c1bea0a840ac75dca19bc6aa05575a33eb9fd058 ]
Currently pmac32_defconfig with SMP=y doesn't build:
arch/powerpc/platforms/powermac/smp.c: error: implicit declaration of function 'cleanup_cpu_mmu_context'
It would be nice for consistency if all platforms clear mm_cpumask and flush TLBs on unplug, but the TLB invalidation bug described in commit 01b0f0eae081 ("powerpc/64s: Trim offlined CPUs from mm_cpumasks") only applies to 64s and for now we only have the TLB flush code for that platform.
So just add an empty version for 32-bit Book3S.
