So for an obscure IA64 specific problem you want the upstream kernel to
port it forward forever instead ?

No - to start with it would be far saner for everything involved if the
4096 processor minority fixed it for the moment in their arch code by
doing something like

	if (max_pids < PIDS_PER_CPU * num_cpus) {
		max_pids = ...
		printk(something informative)
	}

in their __init marked code.

Because when Tejun's stuff is in the patch can go away, and also if it's
not sufficient then the patch above should keep it sane when they go to
32000 cpus or whatever is next.
