No, I don't think this patch has been merged on Arm kernel tree. I searched Arm and Arm64 git repos, none of them has merged this patch.
https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/log/?qt=author&q=Ali+Saidi http://git.armlinux.org.uk/cgit/linux-arm.git/log/?qt=author&q=Ali+Saidi
P.s. Ali missed to include German's review tag, see: https://lore.kernel.org/lkml/458a2de1-dc93-7e2d-5dc5-fbcd670572b6@arm.com/
Do you want us to resend the patch set for adding tags?
Thanks, Leo
