Actually my patch was for improving scheduling on the Pentium Pro /
Pentium II.

I'm about to start looking at improving the scheduling for the Pentium Pro /
Pentium II again. Among other things I want to see if I can use the
MD_SCHED macros to teach Haifa more about scheduling for the Pentium Pro /
Pentium II.

Yep, that's what I'm shooting for.
