i'd not do this patch, mainly because the '100 priority levels' thing is
pretty much an assumption in lots of userspace code. The patch to make
it easier to redefine it is of course fine and was accepted, but i dont
think we want to make it explicit via .config.

It's a bit like with the 3:1 split: you can redefine it easily via
include files, but it's not configurable via .config, because many
people would just play with it and would see things break.

so unless there's really a desire from distributions to actually change
the 100 RT-prio levels (and i dont sense such a desire), we shouldnt do
