That used to be the case until https://www.spinics.net/linux/fedora/fedora-kernel/msg12805.html https://www.spinics.net/linux/fedora/fedora-kernel/msg12805.... which put aarch64 to 4K. I argue there should be a workstation ppc64le spin that does this, but I understand why Fedora doesn't want to put the releng resources towards a niche audience. I agree IBM's autovector stuff is quite good in gcc but there's no substitute for hand-rolled assembly sometimes.
