Also accounted for Ben's comment of using HSRRs rather than disabling RI for OPAL_CALL. This will still increase cost of opal calls a bit due to new mtmsr in FIXUP_ENDIAN return. I have a few more patches that reduce overhead quite a bit, but they won't be suitable for 4.12, so I'll send those out after merge window.
