But now we're back to one of Todd's previous questions about what value SMP_CACHE_BYTES should have in logger.c when he's not running with SMP support. Sigh. I'm not sure, but it looks like if there is not an architecture-specific override, include/linux/cache.h defaults that value to match L1_CACHE_BYTES: #ifndef SMP_CACHE_BYTES #define SMP_CACHE_BYTES L1_CACHE_BYTES #endif include/asm-s390/cache.h does _not_ define SMP_CACHE_BYTES, and it sets L1_CACHE_BYTES thus: #define L1_CACHE_BYTES 256 So I would have to guess that SMP_CACHE_BYTES would be set to 256 on Linux/390 when SMP support is enabled. Again, I hope this helps, Todd.

It looks like it's in the S/390 support for TUX, though. In the include/linux/smp.h header file is this: #ifdef CONFIG_SMP #include <asm/smp.h> For the other architectures, there is an include/asm-archtype/smp.h file that defines cpu_online_map. There isn't one for S/390. If CONFIG_SMP is _not_ defined, then this define happens: #define cpu_online_map 1 So, you could fudge it if you want to try that, or turn off SMP support. But, you'll need SMP support if you use the IBM OCO drivers. (Can't imagine Cisco doing that, but you never know... :) ) Hope this helps. Mark Post
