__SMP__ has been obsolete ever since SMP was made a real config option. This patch is just finishing the job. If a standalone module must continue to use __SMP__, it could do:
#if defined(CONFIG_SMP) && !defined(__SMP__) #define __SMP__ #endif
This has been discussed before. Change during a development kernel is expected. Backwards compatability is not guaranteed. We don't want to fall into that trap.
