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.
