Subject: [patch 3/5] x86-64: remove dead debugging code for !pse setups
Date: Wed, 20 Mar 2013 14:03:30 -0400 [thread overview]
Message-ID: <1363802612-32127-4-git-send-email-hannes@cmpxchg.org> (raw)
In-Reply-To: <1363802612-32127-1-git-send-email-hannes@cmpxchg.org>
No need to maintain addr_end and p_end when they are never actually
read anywhere on !pse setups. Remove the dead code.
