Attached is an updated version of my HMM tests based on linux-5.6.0-rc6.
I ran this OK with Jason's 8+1 HMM patches, Christoph's 1-5 misc HMM clean ups,
and Christoph's 1-4 device private page changes applied.

I'm working on getting my nouveau tests running again on a different test
machine and will report on that when ready.
