MSA is an optional extension to MIPSr4 (I think r4 did not exist either, r5
does).  Octeon 3 implements r5 but not MSA.  It does have the
virtualization extension though.

After octeon 3, cavium/marvell is no longer working on MIPS cores.  I dont
know of any other mainstream source for MIPS cores either.
