I think it's basically OK (just this mips64 thing). I've picked patch 3
already since it's a fix. Once we agree on what to do there, I can queue
it if that helps (I can modify mips64- to mips- in the patch if that's
OK for you, no need to resend for this, just let me know).
I think that later I'll further extend XARCH with new variants to
support ARMv5 and Thumb2, because we have different code for this
and I continue to manually change the CFLAGS to test both.
Thanks,
Willy
