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") Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Nicholas Piggin <npiggin@gmail.com> [mpe: Change log based on comments from Nick] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
