has been removed from the -mm tree.  Its filename was

------------------------------------------------------
Subject: minimize lockdep_on/off side-effect
From: Mathieu Desnoyers <compudj@krystal.dyndns.org>

Minimize lockdep_on/off side-effect on irq tracing in vprintk by using
raw_local_irq_save/restore _around_ lockdep_off/on().

It has the advantage of not losing the IRQ events coming between the lockdep
disabling and the irq disabling.
