Subject: [PATCH v2 00/37] PCI, x86: pci root bus hotplug support
will add pci_stop_and_remove_bus() to support remove bus in
/sys/devices/pci.../pci_bus/...
To rescan root, need to
echo 1 > /sys/bus/pci/rescan
It supports acpi path root bus and legacy root bus.
This patcheset include some IOMM and dmar and pnpacpi fix with device refcount leaking.
also include some bus remove/rescan cleanup.
The patches need to apply to pci/for-linus and pci/linux-next
and [PATCH 00/36] PCI: pci_host_bridge related cleanup and busn_alloc
could get from
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-pci-root-bus-hotplug
-v2: Address most of Bjorn's review, except still keeping .../pci_bus/.../remove
Separate pci root hot add support from acpiphp to pci_root_hp
add hot removal to pci_root_hp
Thanks
Yinghai
