[PATCH] uml: avoid "CONFIG_NR_CPUS undeclared" bogus error messages

      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.
