untested on 8390 hardware, but ought to solve the lockdep false
positive.
-----------------
Subject: locking validator: special rule: 8390.c disable_irq()
From: Ingo Molnar <[email protected]>
8390.c knows that ei_local->page_lock can only be used by an irq
context that it disabled - and can hence take the ->page_lock
without disabling hardirqs. Teach lockdep about this.
