[PATCH V2 0/6] PCI, x86: update MMCFG information when hot-plugging PCI host bridges

[Jiang Liu <liuj97@xxxxxxxxx>]

This patchset enhance pci_root driver to update MMCFG information when
hot-plugging PCI root bridges. It applies to Yinghai's tree at
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-pci-root-bus-hotplug

The second patch is based on Taku Izumi work with some enhancements to
correctly handle PCI host bridges without _CBA method.

v2: split into smaller patches and skip updating MMCFG information when
    MMCFG is disabled

Jiang Liu (6):
  PCI, x86: split out pci_mmcfg_check_reserved() for code reuse
  PCI, x86: split out pci_mmconfig_alloc() for code reuse
  PCI, x86: use RCU list to protect mmconfig list
  PCI, x86: introduce pci_mmcfg_arch_map()/pci_mmcfg_arch_unmap()
  PCI, x86: introduce pci_mmconfig_insert()/delete() for PCI root
    bridge hotplug
  PCI, ACPI, x86: update MMCFG information when hot-plugging PCI host
    bridges
