From 3b15e581981b3ad35809f56d8131d5c19b6da1bd Mon Sep 17 00:00:00 2001 From: Fenghua Yu Date: Thu, 23 Oct 2008 16:51:00 -0700 Subject: x86/PCI: build failure at x86/kernel/pci-dma.c with !CONFIG_PCI On Thu, Oct 23, 2008 at 04:09:52PM -0700, Alexander Beregalov wrote: > arch/x86/kernel/built-in.o: In function `iommu_setup': > pci-dma.c:(.init.text+0x36ad): undefined reference to `forbid_dac' > pci-dma.c:(.init.text+0x36cc): undefined reference to `forbid_dac' > pci-dma.c:(.init.text+0x3711): undefined reference to `forbid_dac This patch partially reverts a patch to add IOMMU support to ia64. The forbid_dac variable was incorrectly moved to quirks.c, which isn't built when PCI is disabled.
