Does this need to be taken as a fix, potentially Cc to stable? Or is
that 5.5 material?

So I though that the S-mode context were kinda aways to be sorted before
M-mode, but I can't find anything guranteeing it. So I think this
actually is a fix, and getting this queued up in the next -rc would
really help me with the nommu stuff - otherwise we'd need to take it
through the riscv tree for 5.5 to avoid conflicts.

Btw, here is my:

Thanks for that.

Alan, if you can respin this patch with an updated commit message, I'll queue
it with a couple of other nits I have lying around, and send it to Thomas by
the end of the week.
