Message-Id: <1233186180-29883-76-git-send-email-mingo@elte.hu>
Date: Wed, 28 Jan 2009 23:42:21 +0000
From: Ingo Molnar <mingo@...e.hu>
To: linux-kernel@...r.kernel.org
Cc: "H. Peter Anvin" <hpa@...or.com>,
Thomas Gleixner <tglx@...utronix.de>,
Ingo Molnar <mingo@...e.hu>
Subject: [PATCH 075/114] x86: remove mach_apic.h
Spread mach_apic.h definitions into genapic.h. (with some knock-on effects
on smp.h and apic.h.)
Signed-off-by: Ingo Molnar <mingo@...e.hu>
