This patch adds PCI based I/O xAPIC hot-add support to ACPIPHP
driver. When PCI root bridge is hot-added, all PCI based I/O xAPICs
under the root bridge are hot-added by this patch. Hot-remove support
is TBD.

Current acpiphp code does not distinguish between the physical presence and
power state of a device/slot. That is, if a device has to be disabled, it
also tries to physically ejects the device. This patch decouples power state
from physical presence. You can now echo to the corresponding sysfs power
control file to repeatedly enable and disable a device without having to
physically re-insert it.

Earlier I reported that Matthew's acpiphp rewrite had problem in powering down
slot on my i386 system. The following patch is needed to get the acpiphp
rewrite properly powering down the slot.

A root bridge may not have directly attached hotpluggable slots under it.
Instead, it may have p2p bridges with slots under it. In this case, we need
to clean up the p2p bridges and slots properly too. Patch below applies on
top of the original patch, and fixes this problem. Without this, acpiphp
leaves behind notify handlers on module unload, and subsequent module load
attempts don't work properly too. Patch was tested on an ia64 Tiger4 box.

This patch converts acpiphp to use the generic PCI resource assignment code.
It's quite large, but most of it is deleting the acpiphp_pci and acpiphp_res
files. It's tested on an hp Integrity rx8620 (which won't work without this
patch). Testers with other hardware welcomed.

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!
