In the octeon defconfig, NR_CPUS is 32. And, some model of OCTEON II do have
> 16 cores. Given the typical memory size equipped by Octeon boards, it sounds
like not a big deal to set a bigger NR_CPUS value as default.

So should this select NR_CPUS_DEFAULT_32 instead?
Cheers

There are OCTEON systems today with 96 CPUs, so something 96 or greater
would let us avoid changing this more than once.
