But maybe it make sense now? Personally I'd rather leave it default to off until it gets through a release cycle without any complaints. Perhaps having r6 select it, or "default y if CONFIG_CPU_MIPSR6" would make sense though, given that you won't be able to use the FPU for r6 userland without it. Paul
