My patch indeed was backed out. If ever I find the time I'll get it
back
in though, but without affecting tlbie (the syntax for tlbie is
different
when you look at the PEM or at the Books; the patch was supposed to
handle
a problem in the cmpXX insns only). Someone should get the PEM and the
architecture books back in line ;-)
