For the record, I found this a little confusing: octeon <= octeon2 <=
octeonp, but it doesn't really matter.

Oops, seems I wasn't paying much attention before.  I think the
previous entry should just be "ISA_MIPS64R2 | INSN_OCTEONP" and
this one should just be "ISA_MIPS64R2 | INSN_OCTEON2".  At least,
it's confusing to leave INSN_OCTEONP out of this one while still
including INSN_OCTEON.

This one should just be "IOCT2".

/* lbux, ldx, lhx and lwx are in the basic instruction section.  */

OK with those changes, thanks.
