PPC64 doesn't compile with CONFIG_SMP=n

Hello Ingo

I've found out that real-time tree doesn't compile for PPC64 with CONFIG_SMP=n.

Think this is due to patch-2.6.21.4-rt10 patch. It has
definitions of following symbols missing: __get_cpu_lock,
__get_cpu_var_locked.

I've attached the patch to fix the problem.
