Please also specify that commit's summary in parens.
says, DSP and MDMX share the same config flag bit.
Without this set, MDMX instructions cause Illegal instruction errors.
Signed-off-by: Matt Turner<mattst88@xxxxxxxxx> --- Is MDMX implemented by anything other than some Broadcom CPUs? Is it totally replaced by DSP?
I had a terrible time finding any documentation on it (which is annoying because Volume IV-b covering MDMX is referenced by all the MIPS64 documents.) but finally found a copy here: www.enlight.ru/docs/cpu/risc/mips/MDMXspec.pdf
If it's dead, it's too bad because it's a pretty cool ISA.
