Subject: [PATCH] mips: mm: Discard ioremap_cacheable_cow() method
Date:   Fri, 20 Jul 2018 23:14:27 +0300
Message-Id: <20180720201427.18845-1-fancer.lancer@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This macro substitution is the shortcut to map cacheable IO memory
with coherent and write-back attributes. Since it is entirely unused
by kernel, lets just remove it.
