Just as heads up. I just tried to build for arm64 but PREEMPT_RT
is not available anymore. Looks like ARCH_SUPPORTS_RT is only
available for !KVM.

It has been announced in v5.9-rc2-rt1
    https://lore.kernel.org/linux-rt-users/20200824154605.v66t2rsxobt3r5jg@linutronix.de/ (local)

and you replied to that mail. That mail contains information why and
what needs to be done to remove that restriction.

D'oh, you have clearly a better memory than me. I forgot about it 
completely. Sorry for the noise.

Thanks,
Daniel
