Subject: [PATCH 4/5] pata_sis: mark most const data static as well
Date: Wed, 7 Sep 2011 11:23:21 -0500 [thread overview]
Message-ID: <1315412602-6560-5-git-send-email-dpmcgee@gmail.com> (raw)
In-Reply-To: <1315412602-6560-1-git-send-email-dpmcgee@gmail.com>
This pushes timing and other values into preinitialized read-only data
sections rather than being inlined into the code. None of these
functions are called more than a handful of times, so reducing code size
makes sense.
