I'm not sure I'd merge it.

The only way I am able to (easily) test Cell code is by using one of
those blades, a QS22 to be precise.

So if the blade support is removed then the rest of the Cell code is
likely to bitrot quickly. Which may be the goal.

I'd be more inclined to support removal of the core dump code. That
seems highly unlikely to be in active use, I don't have the impression
there are many folks doing active development on Cell.

cheers
