You just submit them to the -8u list.

In which case they're inappropriate in aarch64-jdk8u, too.  I can
think of no reason why stability is less important to AArch64 than to
the other ports.  Stability is a key component of software quality,
and I want AArch64 to be of a quality that is just as good as other
ports.

There shouldn't be any differences in shared code between jdk8u and
jdk8u aarch64 except for critical bugs.  Performance patches could be
considered if the performance difference was severe and due to a bug,
but in that case they'd be considered for jdk8u as well.
