kernel/sched.c gets compiled with -fno-omit-frame-pointer, and this was
already done in kernel 1.0 (sic).
Later, it has been modified to be this way only on some architectures.
It might not be an earthshaking amount, but removing it saves some
bytes, and there's no visible breakage when running the modified kernel
on i386.

Is the -fno-omit-frame-pointer still required for some reason, or is
this a relict that could be removed?

of the darkness. There had been need of rain for many days.
"Only a promise," Lao Er said.
