Urgh.. clearly that fell off the table :-(
So yes, that patch works, but as I wrote, I think it's still broken.
Then again, that particular breakage has been there for a long time.
Ooohh.. I have another whole patch-set that fixes that across
architectures which I forgot about too:
https://lkml.kernel.org/r/20191211120713.360281197@infradead.org
that actually included the SH fix.
Then Aneesh got a bunch of those patches merged because he needed it for
Power, but the rest bitrotted again.
Let me rebase/refresh the rest of that and send it out again.
