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.

#include <linux/delay.h>
[PATCH] fix missing includes I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

[PATCH] shpchp: Fix slot state handling Current SHPCHP driver doesn't care about the confliction between hotplug operation via sysfs and hotplug operation via attention button. So if those ware conflicted, slot could be an unexpected state. This patch changes SHPCHP driver to handle slot state properly. With this patch, slot events are handled according to the current slot state as shown at the Table below. Table. Slot States and Event Handling ========================================================================= Slot State Event and Action ========================================================================= STATIC - Go to POWERON state if user initiates (Slot enabled, insertion request via sysfs Slot disabled) - Go to POWEROFF state if user initiates removal request via sysfs - Go to BLINKINGON state if user presses attention button when the slot is disabled - Go to BLINKINGOFF state if user presses attention button when the slot is enabled

[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. This patch also changes acpiphp to use the common hpp code. Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

[PATCH] acpi_pcihp: Fix programming _HPP values This patch fixes the problem that hotplug parameters are not programed when PCI cards are hot-added by ACPIPHP, SHPCHP and PCIEHP driver. The pci_dev structure being hot-added is not bound to ACPI handle, so we need to trace PCI bus tree to find ACPI handle.

[PATCH] PCI Hotplug: shpchp: AMD POGO errata fix This patch fixes the AMD POGO errata on the hotplug controller where the platform will lock up or reboot if PERR/SERR generation is enabled and a slot is sent an enable command. This fix disables PERR/SERR generation before a slot is sent the enable command by first saving related registers, turning off SERR/PERR generation, enabling the slot, then restoring the registers.
