Subject: [PATCH] dc395x [3/5] - remove old debugging stuff
Date: Tue, 9 Mar 2004 15:24:42 +1100	[thread overview]
Message-ID: <20040309042442.GC12274@twibble.org> (raw)
In-Reply-To: <20040309042400.GB12274@twibble.org>

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain; charset=unknown-8bit, Size: 25170 bytes --]

Remove the special versions of kmalloc and kfree and remove the trace
related stuff from the code. None of this is really needed and it is
not really a nice implementation. This also removes all non 7-bit
clean characters to help with David Eger's work to remove and/or
convert them all to UTF8.
