#     powerpc/32s: Fix cleanup_cpu_mmu_context() compile bug
#     
#     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.
#     
#     Fixes: 01b0f0eae081 ("powerpc/64s: Trim offlined CPUs from mm_cpumasks")
