Date: Thu, 25 May 2017 09:43:48 -0600 From: Logan Gunthorpe <logang@...tatee.com> To: linux-kernel@...r.kernel.org, linux-s390@...r.kernel.org Cc: Logan Gunthorpe <logang@...tatee.com>, Martin Schwidefsky <schwidefsky@...ibm.com>, Heiko Carstens <heiko.carstens@...ibm.com>, Al Viro <viro@...IV.linux.org.uk> Subject: [PATCH] s390: provide default ioremap and iounmap declaration Add a default ioremap function which was not provided in all circumstances. (Only when CONFIG_PCI was set). I have designs to use them in scatterlist.c where they'd likely never be called without CONFIG_PCI set, but it is needed to compile. Thus, if the function is ever hit it returns NULL.
