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
