Merge tag 'pci-v3.18-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI fixes from Bjorn Helgaas:
"These are fixes for an issue with 64-bit PCI bus addresses on 32-bit
PAE kernels, an APM X-Gene problem (it depended on a generic change we
removed before merging), a fix for my hotplug device configuration
changes, and a devicetree documentation update.
Resource management:
- Support 64-bit bridge windows if we have 64-bit dma_addr_t (Yinghai Lu)
PCI device hotplug:
- Apply _HPX Link Control settings to all devices with a link (Yinghai Lu)
Generic host bridge driver:
- Add DT binding for "linux,pci-domain" property (Lucas Stach)
APM X-Gene:
- Assign resources to bus before adding new devices (Duc Dang)"
