Merge branch 'pci/resource'
- Protect pci_reassign_bridge_resources() against concurrent
addition/removal (Benjamin Herrenschmidt)
- Fix bridge dma_ranges resource list cleanup (Rob Herring)
- Add PCI_STD_NUM_BARS for the number of standard BARs (Denis Efremov)
- Add "pci=hpmmiosize" and "pci=hpmmioprefsize" parameters to control the
MMIO and prefetchable MMIO window sizes of hotplug bridges
independently (Nicholas Johnson)
- Fix MMIO/MMIO_PREF window assignment that assigned more space than
desired (Nicholas Johnson)
- Only enforce bus numbers from bridge EA if the bridge has EA devices
downstream (Subbaraya Sundeep)
* pci/resource:
PCI: Do not use bus number zero from EA capability
PCI: Avoid double hpmemsize MMIO window assignment
PCI: Add "pci=hpmmiosize" and "pci=hpmmioprefsize" parameters
PCI: Add PCI_STD_NUM_BARS for the number of standard BARs
PCI: Fix missing bridge dma_ranges resource list cleanup
PCI: Protect pci_reassign_bridge_resources() against concurrent addition/removal
