Ufff, why are we backporting this?

It was to fix:
	Stable-dep-of: 2f93bcb3f9aa ("sched/fair: Avoid overflow in place_entity()")
but that's a mess, too many follow-on patches needed here.  I've dropped
it and a few others.

If someone has a "simple" backport of the above commit, we'll take that
instead.

thanks,

It was only pulled in as a dependency of "sched/fair: Avoid overflow in
place_entity()". The whole chain is dropped from the 7.2 queue now.

Peter, Vincent: do you want a context-adapted version of the overflow fix
on 7.2 (h_load.weight becomes load.weight), or should 7.2 just go without
it?

I'm going to prepare a backport of "sched/fair: Avoid overflow in
place_entity()" for v7.2
