I was not aware of your patchset but I am happy to see that code since it
is definitely the right approach and I am willing to help you test it on
arm with the HW I have (probably it will also help remove some code
from arm64 too), let me know when you have a branch ready to test and
if you need any help in rebasing the set.

Thanks,
