Subject: [RFC PATCH v5 0/8] introduce PCI bus notifier chain to get rid of the ACPI PCI subdriver interfaces
Newsgroups: gmane.linux.kernel
Date: Friday 18th January 2013 16:07:38 UTC (over 3 years ago)
This is an RFC patchset to address review comments in thread at:
https://patchwork.kernel.org/patch/1946851/.
The patch just pasts
compilation. If no objection to the new implementation, I will
go on to modify acpiphp driver and conduct tests.

The main changes from V4 to V5 includes:
1) introduce a dedicated notifier chain for PCI buses
2) change pci_slot as built-in driver
3) unify the way to create/destroy PCI slots
4) introduce a kernel option to disable PCIe native hotplug

TODO:
1) change acpiphp as built-in and unify the way to create/destroy ACPI
   based hotplug slots.
2) change other ACPI PCI subdriver in Yinghai's root bridge hotplug series
   to use the PCI bus notifier chain.
3) Remove the ACPI PCI subdriver interface eventaully.

Jiang Liu (8):
  PCI: make PCI device create/destroy logic symmetric
  PCI: split registration of PCI bus devices into two stages
  PCI: add a blocking notifier chain for PCI bus addition/removal
  ACPI, PCI: avoid building pci_slot as module
  PCI, ACPI: hook PCI bus notifications to create/destroy PCI slots
  pci_slot: replace printk(KERN_xxx) with pr_xxx()
  PCI/PCIe: add "pci=nopciehp" to disable PCIe native hotplug
  PCI/PCIe: only claim PME from firmware when CONFIG_PCIE_PME is
    enabled
