Thanks!

So you (a) have a different mach64 than me and (b) run into a different
problem. I am not sure why I do not see your problem on my hardware, stack
usage at that point should be mostly identical.

Michael, you missed the genfb_calc_hsize pullup?

This is the top-20 of stack size offenders in sparc64/GENERIC on netbsd-9:
