Subject: [PATCH v8 00/13] Get rid of the ACPI PCI subdriver mechanism
PCI, ACPI: remove ACPI PCI subdriver mechanism
This patch set is directly derived from two sources:
1) '[PATCH 00/15] PCI/ACPI: Remove "pci_root" sub-driver support' at
https://lkml.org/lkml/2012/12/7/11 from Myron Stowe
The major goal is to resolve any potential sequencing inter-dependencies
by converting sub-driver functionality to being only supported as
statically built-in to the kernel as part of the "pci_root" driver
itself.
2) 'introduce PCI bus notifier chain to get rid of the ACPI PCI subdriver'
at http://lwn.net/Articles/533547/
The major goal is to update PCI slots(pci_slot), ACPI based PCI hotplug
slots(acpiphp), PCIe AER(aer) etc when hot-plugging PCI devices and P2P
bridges, and eventually get rid of the ACPI PCI subdriver interfaces.
This patchset applies to Bjorn's pci-next branch. Patch 1-4 are minor
fixups for 3.9-rc1. Patch 5-8 introduce two hooks into PCI core which
will be called when creating/destroying PCI buses. Patch 9-12 replace
ACPI PCI subdriver interfaces with the new hook mechanism for pci_slot
and acpiphp. Patch 13 removes the ACPI PCI subdriver interfaces.
v7->v8:
Hook directly into the PCI core to replace pci_bus notification
Remove ACPI PCI subdriver related code
Jiang Liu (10):
PCI: do not check is_added flag in pci_remove_bus()
PCI/acpiphp: don't rely on function 0 in disable_device()
ACPI/acpiphp: replace local macros with standard ACPI macros
PCI: introduce platform dependent hooks for creating/destroying PCI
busses
PCI, ACPI: prepare stub functions to handle ACPI PCI (hotplug) slots
PCI, IA64: implement pcibios_{add|remove}_bus() hooks
PCI, x86: implement pcibios_{add|remove}_bus() hooks
PCI, ACPI: handle PCI slot devices when creating/destroying PCI
busses
PCI/acpiphp: do not use ACPI PCI subdriver mechanism
PCI/acpiphp: protect acpiphp data structures from concurrent updating
Myron Stowe (1):
PCI, ACPI: remove support of ACPI PCI subdrivers
Yijing Wang (2):
PCI/acpiphp: use list_for_each_entry_safe() in acpiphp_sanitize_bus()
PCI/acpiphp: use normal list to simplify implementation
