This is a fix for a bug I see on my Toshiba laptop, where the ohci1394
controller gets initialized improperly.  The patch adds two PCI fixups
to arch/i386/pci/fixup.c, one that happens early on to cache the value
of the PCI_CACHE_LINE_SIZE config register, and another that later
restores the value, along with a valid IRQ number and some BAR values.
I've tested it on my laptop, and it prevents me from running into what I
consider to be a major bug: IRQ 11 is disabled by the IRQ debug code,
causing my wireless to break.

Thanks to Rob for the original patch to ohci1394.c and Stefan for lots
of proofreading (and a last minute bug caught in review!) and additional
information collection.  I think the DMI system list is correct, but we
may need to add some more PCI IDs to the PCI_FIXUP macros over time.

The shpc driver registers its probe function for all pci-pci
bridges in the system. Not all of them will be shpc capable, so
look for this capability early in the probe function and return
if there's no work to do on this bridge. The old shpc driver
did some initialization work on all bridges before detecting
that shpc is not supported and unwinds the work it's already done
in that case.

Reduce the SHPC hotplug driver's dependence on ACPI. We don't
walk the acpi namespace anymore to build a list of bridges and
devices. The remaining interaction with ACPI is to run the
_OSHP method to transition control of hotplug hardware from
system BIOS to the shpc hotplug driver, and to run the _HPP
method to get hotplug device parameters like cache line size,
latency timer and SERR/PERR enable from BIOS.

Note that one of the side effects of this patch is that shpchp
does not enable the hot-added device or its DMA bus mastering
automatically now. It expects the device driver to do that.
This may break some drivers and we will have to fix them as
they are reported.

IPR scsi adapter have an exposure today in that they issue BIST to the adapter
to reset the card.  If, during the time it takes to complete BIST, userspace
attempts to access PCI config space, the host bus bridge will master abort the
access since the ipr adapter does not respond on the PCI bus for a brief
period of time when running BIST.  On PPC64 hardware, this master abort
results in the host PCI bridge isolating that PCI device from the rest of the
system, making the device unusable until Linux is rebooted.  This patch makes
use of some newly added PCI layer APIs that allow for protection from
userspace accessing config space of a device in scenarios such as this.

Some PCI adapters (eg.  ipr scsi adapters) have an exposure today in that they
issue BIST to the adapter to reset the card.  If, during the time it takes to
complete BIST, userspace attempts to access PCI config space, the host bus
bridge will master abort the access since the ipr adapter does not respond on
the PCI bus for a brief period of time when running BIST.  On PPC64 hardware,
this master abort results in the host PCI bridge isolating that PCI device
from the rest of the system, making the device unusable until Linux is
rebooted.  This patch is an attempt to close that exposure by introducing some
blocking code in the PCI code.  When blocked, writes will be humored and reads
will return the cached value.  Ben Herrenschmidt has also mentioned that he
plans to use this in PPC power management.
