gcc-10 warns that the 32-bit zero cannot be shifted more than
32 bits to the right:

This is harmless, and the warning is a little bit silly for
a zero constant, but it's trivial to fix by making it an
unsigned long, so do that.

Happy to queue via arm64 for 5.8. Does that work for you, Arnd, or were you
planning to get this in sooner than that?
