From 3922920026c0242d752e62a3c88b758715c5c42f Mon Sep 17 00:00:00 2001 From: Logan Gunthorpe Date: Thu, 6 Jul 2017 15:35:40 -0700 Subject: tile: provide default ioremap declaration Add a default ioremap function which was not provided in all circumstances. (Only when CONFIG_PCI and CONFIG_TILEGX was set). I have designs to use them in scatterlist.c where they'd likely never be called with this architecture, but it is needed to compile. Thus, if the function is ever hit it returns NULL.
