Message-Id: <20090407151012.120C51D046E@basil.firstfloor.org>
Date: Tue, 7 Apr 2009 17:10:11 +0200 (CEST)
From: Andi Kleen <andi@...stfloor.org>
To: linux-kernel@...r.kernel.org, linux-mm@...ck.org, x86@...nel.org
Subject: [PATCH] [14/16] x86: MCE: Rename mce_notify_user to mce_notify_irq
Impact: cleanup
Rename the mce_notify_user function to mce_notify_irq. The next
patch will split the wakeup handling of interrupt context
and of process context and it's better to give it a clearer
name for this.
