No, I'm sure it can happen on other architectures too.
I think the only thing that makes parisc trigger this is that its
WARN_ON() is slightly different from others, and uses the
"__ret_warn_on" a few more times, and that just happens to make the
compiler decide to simplify all those tests.
Or something like that.
