Either ioat needs to stop using cpu_physical_id() if SMP=n, or the supported architectures (i386, x86_64, ia64) should provide a non-SMP version of cpu_physical_id(). Preferably the latter, I'd say. Something like this, I suppose... From: Andrew Morton <[EMAIL PROTECTED]> i386, x86_64 and ia64 implement cpu_physical_id() if CONFIG_SMP=y. Provide a uniprocessor stub so that callers will dtrt.
