That problem must be lkml.kernel.org/g/1459978040-2226-1-git-send-email-ahs3@redhat.com . Ie, the fact that CONFIG_DEVPORT "cannot really be used and it allows us to crash a kernel from user space" on arm64.

I fail to see how this patch helps your problem. And if one applies this patch on top of v4.6-rc4 and does make ARCH=arm64 defconfig
one gets a .config that still has CONFIG_DEVPORT=y
So my guess is that it wasn't this patch that solved that arm64 problem.
Thanks,
