("agp: Support 64-bit APBASE"), which we merged in v3.14-rc1. We've warned about the conflict between the GART and PCI resources and cleared out the PCI resource for a long time, but aftere501b3d87f
, we still *use* that cleared-out PCI resource. I think the GART resource is incorrect, so this patch removes it" * tag 'pci-v3.14-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: Revert "[PATCH] Insert GART region into resource map"
