That's a novel position. You do realize that removing that
capability breaks drivers?

But if that's what is keeping you from fixing the lockdep bug,
why haven't you submitted patches to remove IRQF_DISABLED from
the kernel, and update all the drivers relying on IRQs being
enabled when their handlers run?

At least that would get the appropriate level of discussion.
