Message-Id: <1302711073-31985-1-git-send-email-farnold@amd64.org> Date: Wed, 13 Apr 2011 18:11:13 +0200 From: Frank Arnold <farnold@...64.org> To: Ingo Molnar <mingo@...e.hu>, "H. Peter Anvin" <hpa@...or.com>, Thomas Gleixner <tglx@...utronix.de> Cc: <linux-kernel@...r.kernel.org> Subject: [PATCH] x86: Clean up mwait_play_dead From: Frank Arnold <frank.arnold@....com> Commit 93789b32dbf355e70f18b17a82e8661677a7f7fb introduced cpuinfo_x86 *c for brevity. It is used to check for the mwait feature flag. The same can be done with a subsequent check for clflsh and save us a second per-cpu pointer dereference.
