Hash Suite for Android: free password hash cracker in your pocket
[<prev] [next>] [day] [month] [year] [list]
Message-Id: <200905112257.03981.arnd@arndb.de>
Date:	Mon, 11 May 2009 22:57:03 +0000
From:	Arnd Bergmann <arnd@...db.de>
To:	linux-kernel@...r.kernel.org, Ralf Baechle <ralf@...ux-mips.org>
Subject: [PATCH] mips: use PIT_TICK_RATE in i8253

Using PIT_TICK_RATE instead of CLOCK_TICK_RATE allows
us to later change CLOCK_TICK_RATE to a more sensible
time base value for platforms that do not base their
system timer off an i8253.
