This change makes it treat r6 like > it treats r2 (i.e. there is still a Cause.TI bit), which sounds correct > to me. I'm guessing cpu_has_mips_r6 doesn't imply cpu_has_mips_r2. Correct, R6 is not backwards compatible with R2 so it doesn't set the R2 flag and consequently any compatibility that does exist has to be handled explicitly; see 28/70 for the details of the flag setup.
