To enable ABIs you'll need Kconfig symbols, cpu_has_64bit_addresses
isn't going to be very useful for that.  Which kinda rather was the
point of this patch - to use the existing Kconfig symbol rather than
two redundant defines that caused a lot weird cargo culting.

You don't happen to have a git tree available somewhere?
