That won't be me ;). For any kernel compiled with CONFIG_CPUSETS (which includes the major distros I am aware of), one can just count the bits in the top cpusets 'cpus' value, which is always the online CPU mask. Even if your user level software is making no conscious use of cpusets, this works, for kernels so configured. If there is someone who needs both a faster sysconf (_SC_NPROCESSORS_CONF) and a kernel without CPUSETS configured, then they will have to speak up for themselves. -- I won't rest till it's the best ...
