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
-v3: add mmconf_added to simply free path, also make pci_mmconfig_insert()
to process extra exist case --- By Yinghai
-v4: tune arch_acpi_pci_root_add() to handle a corner case raised by Kenji
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
