* pci/misc:
PCI: Enable INTx if BIOS left them disabled
ia64/PCI: Set IORESOURCE_ROM_SHADOW only for the default VGA device
x86/PCI: Set IORESOURCE_ROM_SHADOW only for the default VGA device
PCI: Update outdated comment for pcibios_bus_report_status()
PCI: Cleanup per-arch list of object files
PCI: cpqphp: Fix hex vs decimal typo in cpqhpc_probe()
x86/PCI: Fix function definition whitespace
x86/PCI: Reword comments
x86/PCI: Remove unnecessary local variable initialization
PCI: Remove unnecessary list_empty(&pci_pme_list) check

Setting the IORESOURCE_ROM_SHADOW flag on a VGA card other than the primary
prevents it from reading its own ROM. It will get the content of the
shadow ROM at C000 instead, which is of the primary VGA card and the driver
of the secondary card will bail out.
Fix this by checking if the arch code or vga-arbitration has already
determined the vga_default_device, if so only apply the fix to this primary
video device and let the comment reflect this.

pci_scan_bus_with_sysdata() and pcibios_scan_root() are quite similar:
pci_scan_bus_with_sysdata
pci_scan_bus_on_node(..., &pci_root_ops, -1)
pcibios_scan_root
pci_scan_bus_on_node(..., &pci_root_ops, get_mp_bus_to_node(busnum))
get_mp_bus_to_node() returns -1 if it couldn't find the node number, so
this removes pci_scan_bus_with_sysdata() and uses pcibios_scan_root()
instead.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

The PCI core caches the PCIe Capability offset in pci_dev->pcie_cap, so
use that instead of pci_find_capability(). Use pci_bus_set_ops() when
replacing the device pci_ops. And use #defines instead of numeric
constants.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitconst,
and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Pull main drm updates from Dave Airlie:
"This is the main merge window request for the drm.
It's big, but jam packed will lots of features and of course 0
regressions. (okay maybe there'll be one).
Highlights:
- new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus
(qemu only). These drivers use the generic modesetting drivers.
- initial prime/dma-buf support for i915, nouveau, radeon, udl and
exynos
- switcheroo audio support: so GPUs with HDMI can turn off the sound
driver without crashing stuff.
- There are some patches drifting outside drivers/gpu into x86 and
EFI for better handling of multiple video adapters in Apple Macs,
they've got correct acks except one trivial fixup.
- Core:
edid parser has better DMT and reduced blanking support,
crtc properties,
plane properties,
- Drivers:
exynos: add 2D core accel support, prime support, hdmi features
intel: more Haswell support, initial Valleyview support, more
hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of
cleanups and fixes
radeon: more HDMI audio support, improved GPU lockup recovery
support, remove nested mutexes, less memory copying on PCIE, fix
bus master enable race (kexec), improved fence handling
gma500: cleanups, 1080p support, acpi fixes
nouveau: better nva3 memory reclocking, kepler accel (needs
external firmware rip), async buffer moves on nv84+ hw.
I've some more dma-buf patches that rely on the dma-buf merge for vmap
stuff, and I've a few fixes building up, but I'd decided I'd better
get rid of the main pull sooner rather than later, so the audio guys
are also unblocked."

Despite lots of investigation into why this is needed we don't
know or have an elegant cure. The only answer found on this
laptop is to mark a problem region as used so that Linux doesn't
put anything there.
Currently all the users add reserve= command lines and anyone
not knowing this needs to find the magic page that documents it.
Automate it instead.

Since Matthew's efi/vga changes on non-EFI machines we were failing
to tell the vgaarb/switcheroo what the default device was, this
sets the default device in the quirk if none has been set before.
This fixes the switcheroo on my T410s.

Many host bridges support a 4k config space, so check them directy
instead of using quirks to add them.
We only need to do this extra check for host bridges at this point,
because only host bridges are known to have extended address space
without also having a PCI-X/PCI-E caps. Other devices with this
property could be done with quirks (if there are any).
As a bonus, we can remove the quirks for AMD host bridges with family
10h and 11h since they're not needed any more.
With this patch, we can get correct pci cfg size of new Intel CPUs/IOHs
with host bridges.

Impact: cleanup
Now that arch/x86/pci/pci.h is used in a number of other places as well,
move the lowlevel x86 pci definitions into the architecture include files.
(not to be confused with the existing arch/x86/include/asm/pci.h file,
which provides public details about x86 PCI)

Convert printks to use dev_printk().
I converted DBG() to dev_dbg(). This DBG() is from arch/x86/pci/pci.h and
requires source-code modification to enable, so dev_dbg() seems roughly

We want to allow different implementations of pci_raw_ops for standard
and extended config space on x86. Rather than clutter generic code with
knowledge of this, we make pci_raw_ops private to x86 and use it to
implement the new raw interface -- raw_pci_read() and raw_pci_write().

On the "MSI K8T Neo2-FIR" board the BIOS disables the onboard
soundcard, if a second PCI soundcard is present.
This patch sets the korrect register bit to enable the onboard sound.
Removed old code in /drivers/pci/quirks.c that only checks for the
PCI-ID and fires on any Board with VIA 8237.
New code in /arch/i386/pci/fixup.c checks the DMI-tables and only runs
on the specific board.
