I think I have what could be 4 separate patches for smp here: (combined in the attached patch) 1. add topology_init - fixes a boot time crash 2. setup cpu_possible_map - actually boot the additional cpu's 3. fix smp related section mismatch warnings 4. add the missing *_can_lock macros If you are running a local framebuffer, you may encounter a problem with vmalloc. Adding "migration_cost=10000" to the kernel command line should cover up the problem. I haven't had the time to give it a thorough testing and see if it self-recompiles recently, but I was previously able to successfully rebuild the kernel with "make -j6" on a dual SuperSPARC II. Bob
