Slight scarcasm. yes too hard.

http://man.openbsd.org/qsort

having said that this specific sort is somewhere deep in kernel boot land. and kernel code can't really use the standard library. I am not sure if there is a standard kernel sort.

Of course it can. Just extract the qsort implementation to a static library pulled in by the kernel and by libc.
