Due to load balance / test queue maintenance on Juno-r2 devices,
We have stopped running 64k page testing on mainline and next instead
running on stable-rc builds.

Allow me a day to test Linux next 64k page size build testing on
Juno-r2 and get back to you.

I have tested Linux next arm64 64k page size builds on Juno-r2 and confirm that
the reported issue is fixed now.
