That's a good idea. I was trying to figure out where it should go and
I looked at Documentation/process/submit-checklist.rst and point 4 had
me a bit puzzled:

4) ppc64 is a good architecture for cross-compilation checking because it
tends to use ``unsigned long`` for 64-bit quantities.

It took me a while to realize that this must have been written when 64
bit systems were new and rare. :P This documentation is old old old...
