Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] pciehp: clean-up how we request control of hotplug hardware This patch further tweaks how we request control of hotplug controller hardware from BIOS. We first search the ACPI namespace corresponding to a specific hotplug controller looking for an _OSC or OSHP method. On failure, we successively move to the ACPI parent object, till we hit the highest level host bridge in the hierarchy. This allows for different types of BIOS's which place the _OSC/OSHP methods at various places in the acpi namespace, while still not encroaching on the namespace of some other root level host bridge. This patch also introduces a new load time option (pciehp_force) that allows us to bypass all _OSC/OSHP checking. Not supporting these methods seems to be be the most common ACPI firmware problem we've run into. This will still _not_ allow the pciehp driver to work correctly if the BIOS really doesn't support pciehp (i.e. if it doesn't generate a hotplug interrupt). Use this option with caution. Some BIOS's may deliberately not build any _OSC/OSHP methods to make sure it retains control the hotplug hardware. Using the pciehp_force parameter for such systems can lead to two separate entities trying to control the same hardware.

PCIE: Make use of the previously split out pcie_init_enable_events() function Make use of the previously split out pcie_init_enable_events() function to reinitialize the hotplug hardware on resume from suspend, but only when pciehp_force==1. Otherwise behaviour is unmodified.

int pciehp_disable_slot(struct slot *p_slot);
PCIe: fix double initialization bug Earlier patches to split out the hardware init for PCIe hotplug resulted in some one-time initializations being redone on every resume cycle. Eg. irq/polling initialization. This patch splits the hardware init into two parts, and separates the one-time initializations from those so that they only ever get done once, as intended.

[PATCH] PCI Hotplug: add common acpi functions to core shpchprm_acpi.c and pciehprm_acpi.c are nearly identical. In addition, there are functions in both these files that are also in acpiphp_glue.c. This patch will remove duplicate functions from shpchp, pciehp, and acpiphp and move this functionality to pci_hotplug, as it is not hardware specific. Get rid of shpchprm* and pciehprm* files since they are no longer needed. shpchprm_nonacpi.c and pciehprm_nonacpi.c are identical, as well as shpchprm_legacy.c and can be replaced with a macro.
