Subject: [PATCH] x86: use PIT_TICK_RATE consistently
Date: Mon, 11 May 2009 22:50:15 +0000	[thread overview]
Message-ID: <200905112250.16176.arnd@arndb.de> (raw)
In-Reply-To: 20090511222702.352192505@arndb.de

On x86, the CLOCK_TICK_RATE is defined in terms of PIT_TICK_RATE,
from the original i8253 PIT frequency. Change all users to
refer to PIT_TICK_RATE directly, in order to reduce the number
of overloaded meanings for CLOCK_TICK_RATE.
