Subject: [PATCH 00/40] PCI, ACPI, x86: pci root bus hotplug support
It supports pci root bus removal with
echo "PCI0 3" > /sys/kernel/debug/acpi/sci_notify
add with
echo "PCI0 0" > /sys/kernel/debug/acpi/sci_notify
based on pci/next
We need to separate pci root bus add from acpiphp. so user could only root bus
hotplug and pciehp that will make system fw simple.
Also later CONFIG_HOTPLUG will be removed, so pci root bus hotplug will be
enabled by default and user still need select acpiphp and pciehp for normal
pci device hotplug support.
could get from
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-pci-root-bus-hotplug
