To prove I'm not completely slack, I went spelunking through the
source to see how hwpmc hooks into things.

There's no HWPMC_HOOKS used anywhere in sys/mips/* or sys/mips/*/*,
save config files.

I thus have a feeling the hwpmc glue for sampling mode just isn't
there for any MIPS core at the present time.

Would someone more versed in the ways of MIPS stack frame magic and
trap handling care to take a stab at it?

Thanks,
