Yeah, perhaps a better commit title would have been to
write:

time/ntp: Fix adjtimex freq validation code build warning on 32-bit systems

To make it clear that the problem fixed is a 32-bit
warning, and that the fix for that is to only check on
64-bit systems.

I agreed with your BITS_PER_LONG check when I reviewed your
patch, people usually do an ugly #ifdef, I think this
in line check form is nicer.

Thanks,

Ingo
