Subject: [PATCH 3/9] Generic timekeeping i386 arch specific changes, part 1
Date: Wed, 10 Aug 2005 19:18:18 -0700	[thread overview]
Message-ID: <1123726698.32531.41.camel@cog.beaverton.ibm.com> (raw)
In-Reply-To: <1123726619.32531.38.camel@cog.beaverton.ibm.com>

All,
	The conversion of i386 to use the generic timekeeping subsystem has
been split into 6 parts. This patch, the first of six, is just a simple
cleanup for the i386 arch in preperation of moving the the generic
timekeeping infrastructure. It simply moves some code from timer_pit.c
to i8259.c.
	
It applies on top of my timeofday-core patch. This patch is part the
timeofday-arch-i386 patchset, so without the following parts it is not
expected to compile (although just this one should).
	

thanks
-john
