Not directly related but seeing the eret here reminded me that we're still
not handling the R4000PC/SC v2.2/v3.0 erratum 6 where returning from a
cache error exception handler to the eret instruction of another exception
handler that was just about to return to user mode was not being
treated properly.
In case you care ;-)
