All I mean is, if the kernel doesn't explode on existing systems by changing
the upper limit to 64, then we should do that. If you're not comfortable
that the Thunder code can handle that, then leave the thunder default as 32,
like you do in the current patch. It just seems odd not to change the
maximum number, since it's an arbitrary limit from my perspective.

FWIW my Juno happily boots with a NR_CPUS=64 kernel.

It looks like if it's fine to set the general default to NR_CPUS=64
even if the kernel might not yet boot more than 32 cpus. Will make
this change separately and drop it in this patch.
