Subject: [PATCH 00/23] PCI, x86: pci root bus hotplug support
Newsgroups: gmane.linux.kernel
Date: Tuesday 6th March 2012 07:13:37 UTC (over 4 years ago)
will add pci_stop_and_remove_bus() to support remove bus in
/sys/devices/pci.../pci_bus/...

it support pci root bus removal.

To rescan root, need to
echo 1 > /sys/bus/pci/rescan_root

this patcheset include some IOMM and dmar and pnpacpi fix with device
refcount leaking.

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

Thanks

Yinghai
