Move PCI_VENDOR_ID_VMWARE from device-specific files to pci_ids.h.
It is useful to always have access to it, especially when accessing
subsystem_vendor_id on emulated devices.

Pull staging updates from Greg KH:
"Here is the big staging patch set for 3.18-rc1.
Once again, we are deleting more code than we added, with something
like 150000 lines deleted overall. Some of this is due to drivers
being added to the networking tree, so the old versions are removed
here, but even then, the overall difference is quite good.
Other than driver deletions, lots and lots and lots of minor cleanups
all over the place. Full details are in the changelog"

Move channel parameter memory setup functions and macros into a new
submodule ipu-cpmem. In the process, cleanup arguments to the functions
to take a channel pointer instead of a pointer into cpmem for that
channel. That allows the structure of the parameter memory to be
private to ipu-cpmem.c.

Taint the kernel if the semaphores, enable_rc6, enable_fbc, or ppgtt
module parameters are modified. These module parameters are for
debugging and testing only, and should never be changed from their
platform specific default values by the users. We do not provide support
for people enabling all the experimental features. Make this clear by
tainting the kernel if the parameters are set.

As we use WC updates of the PTE, we are responsible for notifying the
hardware when to flush its TLBs. Do so after we zap all the PTEs before
suspend (and the BIOS tries to read our GTT).

Linus commit 05c63c2ff23a80b654d6c088ac3ba21628db0173 modified the
runtime suspend/resume paths to skip over display-related tasks to
avoid locking issues on resume.
Unfortunately, this resulted in the display hardware being left in
a partially initialised state, preventing subsequent modesets from
completing.
This commit unifies the (many) suspend/resume paths, bringing back
display (and fbcon) handling in the runtime paths.

Preparation for some runtime pm fixes. Currently we skip over fbcon
suspend/resume in the runtime path, which causes issues on resume if
fbcon tries to write to the framebuffer before the BAR subdev has
been resumed to restore the BAR1 VM setup.
As we might be woken up via a sysfs connector, we are unable to call
fb_set_suspend() in the resume path as it could make its way down to
a modeset and cause all sorts of locking hilarity.
To solve this, we'll just delay the fbcon resume to a workqueue.

Xorg (and any non-DRM client really) doesn't have permission to directly
touch VRAM on nv50 and up, which the fence code prior to g84 depends on.
It's less invasive to temporarily grant it premission to do so, as it
previously did, than it is to rework fencenv50 to use the VM. That
will come later on.

Some of the Thinkpads' firmware will issue a backlight change request
through i915 operation region unconditionally on AC plug/unplug, the
backlight level used is arbitrary and thus should be ignored. This is
handled by commit 0b9f7d93ca61 (ACPI / i915: ignore firmware requests
for backlight change). Then there is a Dell laptop whose vendor backlight
interface also makes use of operation region to change backlight level
and with the above commit, that interface no long works. The condition
used to ignore the backlight change request from firmware is thus
changed to: if the vendor backlight interface is not in use and the ACPI
backlight interface is broken, we ignore the requests; oterwise, we keep
processing them.
Fixes: 0b9f7d93ca61 (ACPI / i915: ignore firmware requests for backlight change)

Add a module parameter to disable the radeon GPU backlight
controller to override the automatic detection. Some
laptops seems to indicate that they use the integrated
controller, but appear to actually use an external
controller.

Otherwise the bit remains set in rdev->ih.rptr, so the wptr can never
match that and we still have an infinite loop.

Ring init and cleanup are not balanced because we re-init the rings on
resume without having cleaned them up on suspend. This leads to the

This patch extends the current convention of checking whether a
resource is already allocated before allocating it during ring init.
Longer term it might make sense to only init the rings once.

A mismatch between FB and LTC's idea of how big a large page is causes
issues such as black "holes" in rendering to occur on some boards
(those where LTC is configured for 64KiB large pages) when compression
is used.
Confirmed to fix at least the GK107 MBP.

DP port limited color range knob is in PIPECONF for which we
already have readout code.
