Subject: [PATCH] arch/alpha: Remove dead code
Date:   Sun,  4 Aug 2019 00:47:36 +0530
Message-Id: <1564859856-5916-1-git-send-email-jrdr.linux@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

These are dead code since 2.6.11. If there is no plan to use
it further, this can be removed forever.
