ok, that WARN_ON is over-eager. Fix is below:
--------------
Subject: lock validator: remove softirq.c WARN_ON
From: Ingo Molnar <[email protected]>
there is nothing wrong with calling local_bh_disable() in irqs-off
section (as long as the local_bh_enable isnt done with irqs-off),
so remove this over-eager WARN_ON().
