Sorry, I must missed something (in my system, build errors are only
recorded on first sight)..

wfg /c/linux% for arch in arch/*/; do grep -ir -q atomic64 $arch || echo $arch; done
arch/c6x/
arch/h8300/
arch/mn10300/
arch/score/
arch/unicore32/

So the above archs are likely still missing atomic64_t support.
However it should be trivial to add support to them, by adding
"select GENERIC_ATOMIC64" lines to them.

Thanks,
Fengguang
