From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Logan Gunthorpe Date: Wed, 24 May 2017 16:00:52 -0600 Message-Id: <1495663252-22434-1-git-send-email-logang@deltatee.com> Subject: [PATCH] um: add dummy ioremap and iounmap functions Sender: linux-kernel-owner@vger.kernel.org To: linux-kernel@vger.kernel.org, user-mode-linux-devel@lists.sourceforge.net Cc: Logan Gunthorpe , Stephen Bates , Jeff Dike , Richard Weinberger List-ID: The user mode architecture does not provide ioremap or iounmap, and because of this, the arch won't build when the functions are used in some core libraries. I have designs to use these functions in scatterlist.c where they'd almost certainly never be called on the um architecture but it does need to compile.
