nptl: Eliminate <smp.h> and __is_smp
Most systems are SMP, so optimizing for the UP case is no longer approriate. A dynamic check based on the kernel identification has been only implemented for i386 anyway. To disable adaptive mutexes on sh, define DEFAULT_ADAPTIVE_COUNT as zero for this architecture. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
