Date: Sun, 14 Dec 2014 14:59:41 +0200 From: "Michael S. Tsirkin" <mst@...hat.com> To: linux-kernel@...r.kernel.org Cc: trivial@...nel.org, David Howells <dhowells@...hat.com>, Koichi Yasutake <yasutake.koichi@...panasonic.com>, linux-am33-list@...hat.com Subject: [PATCH] mn10300: drop dead code pci-iomap.c was (apparently, mistakenly) reintroduced as part of commit 83c2dc15ce824450e7044b9f90cd529c25747ae0 MN10300: Handle cacheable PCI regions in pci_iomap() probably as side-effect of forward-porting the patch from an old kernel. It's not really needed: the generic pci_iomap does the right thing here. The new file isn't compiled so it's safe to drop.
