Let's include cpudata.h in topology_64.h.

Nitpick - if you are going to resend this patch, then please
order the two includes in alphabetic order.

For two includes this looks like bikeshedding, but when we add
more having them in a defined arder prevents merge conflicts.
And makes it readable too.

We also sometimes order the includes with the longest lines topmost,
and lines with the ame length are ordered alphabetically.
But this is not seen so often.

	Sam

It depends on the maintainer's thought. :)
