From a21a2fd4036f9a572415a7543896a1163c211ee5 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Thu, 24 Nov 2011 21:10:12 +0200 Subject: sparc: switch to GENERIC_PCI_IOMAP sparc copied pci_iomap from generic code, probably to avoid pulling the rest of iomap.c in. Since that's in a separate file now, we can reuse the common implementation. Signed-off-by: Michael S.
