kernel mode. In the past the user mode check was in between.

It shouldn't be that difficult to make it say "in user mode" or "in
kernel mode" depending on which it was... or just remove that phrase
altogether and let the following output indicate whether it was in
kernel mode.

Well printing the correct message is only part of it: do "we" want to =20
pass guarded load errors (RapidIO bus errors) to user space or not?

Yes.

And if we pass them, should we print a kernel message at all?

Yes (but maybe ratelimited).
