Good point, interesting that my build test didn't catch it ... I'll add another patch on top before I ask Linus to pull.

Commit fea80311a939a746533a6d7e7c3183729d6a3faf "iomap: make IOPORT/PCI mapping functions conditional" Broke powerpc build without CONFIG_PCI as we would still define pci_iomap(), which overlaps with the new empty inline in the headers. Make our implementation conditional on CONFIG_PCI Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> --- arch/powerpc/kernel/iomap.c | 2 ++ 1 files changed, 2 insertions(+), 0 deletions(-)
