From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Subject: [PATCH] move PIT_TICK_RATE to linux/timex.h Date: Mon, 11 May 2009 22:55:36 +0000 Message-ID: <200905112255.37215.arnd@arndb.de> References: <20090511222702.352192505@arndb.de>> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: Received: from moutng.kundenserver.de ([212.227.126.171]:65441 "EHLO moutng.kundenserver.de" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751845AbZEKWzx (ORCPT ); Mon, 11 May 2009 18:55:53 -0400 Content-Disposition: inline Sender: linux-arch-owner@vger.kernel.org List-ID: To: linux-arch@vger.kernel.org, x86@kernel.org, Richard Henderson , Ralf Baechle , Takashi Iwai , Dmitry Torokhov Cc: linux-kernel@vger.kernel.org, Alan Cox PIT_TICK_RATE is currently defined in four architectures, but in three different places. While linux/timex.h is not the perfect place for it, it is still a reasonable replacement for those drivers that traditionally use asm/timex.h to get CLOCK_TICK_RATE and expect it to be the PIT frequency.
