Subject: [PATCH 2/6] new timeofday i386 arch specific changes, part 1 for -mm (v.B3)
Date: Fri, 17 Jun 2005 19:58:04 -0700 [thread overview]
Message-ID: <1119063484.9663.4.camel@cog.beaverton.ibm.com> (raw)
In-Reply-To: <1119063400.9663.2.camel@cog.beaverton.ibm.com>
Andrew, All,
To hopefully improve the review-ability of my changes, I've split up my
arch-i386 patch into four chunks. This patch is just a simple cleanup
for the i386 arch in preparation of moving the the new timeofday
infrastructure. It simply moves some code from timer_pit.c to i8259.c.
It applies on top of my timeofday-core_B3 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).
Andrew, please consider for inclusion for testing into your tree.
thanks
-john
