Olaf Hering <olh@suse.de> Olaf reported UML doesn't build for him with a clear analisys of what happened - we're using NR_CPUS in files linked against glibc headers. Seems like it defines CONFIG_SMP but not CONFIG_NR_CPUS, so we get CONFIG_NR_CPUS undeclared. The fix is to move the declaration away from that header file and move it in asm-um headers, and to add that header where needed.
