Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support.
Subsequent patch will address this.
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the
platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is
maybe a bit too much, hence the num_ioctls assignment prevents a
const driver structure.
- arcpgu, because that is stuck behind a pending tiny-fication series
from me.
- legacy drivers, because legacy requires non-const drm_driver.
Note that for armada I also went ahead and made the ioctl array const.
Only cc'ing the driver people who've not been converted (everyone else
is way too much).

Since commit 9a40401cfa ("lib/scatterlist: Do not limit max_segment to
PAGE_ALIGNED values") the max_segment input to sg_alloc_table_from_pages()
does not have to be any special value. The new algorithm will always
create something less than what the user provides. Thus eliminate this
confusing constant.
- vmwgfx should use the HW capability, not mix in the OS page size for
calling dma_set_max_seg_size()
- i915 uses i915_sg_segment_size() both for sg_alloc_table_from_pages
and for some open coded sgl construction. This doesn't change the value
since rounddown(size, UINT_MAX) == SCATTERLIST_MAX_SEGMENT
- drm_prime_pages_to_sg uses it as a default if max_segment is zero,
UINT_MAX is fine to use directly.

At one point, the GPU command verifier and user-space handle manager
couldn't properly protect GPU clients from accessing each other's data.
Instead there was an elaborate mechanism to make sure only the active
master's primary clients could render. The other clients were either
put to sleep or even killed (if the master had exited). VRAM was
evicted on master switch. With the advent of render-node functionality,
we relaxed the VRAM eviction, but the other mechanisms stayed in place.
Now that the GPU command verifier and ttm object manager properly
isolates primary clients from different master realms we can remove the
master switch related code and drop those legacy features.

"This has two exciting community drivers for ARM Mali accelerators.
Since ARM has never been open source friendly on the GPU side of the
house, the community has had to create open source drivers for the
Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
series. Well done to all involved and hopefully this will help ARM
head in the right direction.
There is also now the ability if you don't have any of the legacy
drivers enabled (pre-KMS) to remove all the pre-KMS support code from
the core drm, this saves 10% or so in codesize on my machine.
i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
moves out of staging.

This means we have no reliable way to destinguish between coherent
hardware IOMMU DMA address translations and incoherent SWIOTLB DMA
address translations, which we can't handle. So always presume the
former. This means that if anybody forces SWIOTLB without also setting
the vmw_force_coherent=1 vmwgfx option, driver operation will fail,
like it will on most other graphics drivers.

This is only used by drm_irq_install(), which is an optional helper.
For legacy pci devices this is required (due to interrupt sharing without
msi/msi-x), and just making this the default exactly matches the behaviour
of all existing drivers using the drm_irq_install() helpers. In case that
ever becomes wrong drivers can roll their own irq handling, as many
drivers already do (for other reasons like needing a threaded interrupt
handler, or having an entire pile of different interrupt sources).

This field was previously used to prevent a lookup of a resource before its
constructor had run to its end. This was mainly intended for an interface
that is now removed that allowed looking up a resource by its device id.
Currently all affected resources are added to the lookup mechanism (its
TTM prime object is initialized) late in the constructor where it's OK to
look up the resource.
This means we can change the device resource_lock to an ordinary spinlock
instead of an rwlock and remove a locking sequence during lookup.

Initially vmware buffer objects were only used as DMA buffers, so the name
DMA buffer was a natural one. However, currently they are used also as
dumb buffers and MOBs backing guest backed objects so renaming them to
buffer objects is logical. Particularly since there is a dmabuf subsystem
in the kernel where a dma buffer means something completely different.
This also renames user-space api structures and IOCTL names
correspondingly, but the old names remain defined for now and the ABI
hasn't changed.
There are a couple of minor style changes to make checkpatch happy.

We have had problems displaying fbdev after a resume and as a
workaround we have had to call vmw_fb_refresh(). This has had
a number of unwanted side-effects. The root of the problem was,
however that the coalesced fbdev dirty region was not empty on
the first dirty_mark() after a resume, so a flush was never
scheduled.
Fix this by force scheduling an fbdev flush after resume, and
remove the workaround.

This was requested by Daniel, and things were getting
a bit hard to reconcile, most of the conflicts were
trivial though.
It was used to early block fbdev dirty processing. Replace it with an
unprotected check of the par->dirty.active field. While this might
race with the vmw_fb_off() function, we do a protected check later so
the race will at worst lead to grabbing and releasing a couple of locks.

When we are running without fbdev, transitioning from the login screen to
X or gnome-shell/wayland will cause a vt switch and the driver will disable
svga mode, losing all modesetting resources. However, the kms atomic state
does not reflect that and may think that a crtc is still turned on, which
will cause device errors when we try to bind an fb to the crtc, and the
screen will remain black.
Fix this by turning off all kms resources before disabling svga mode.

This becomes necessary after the fix: "Work around mode set

In a low-memory 2D VM, fbdev can take up a large percentage of
available memory, making them unavailable for other DRM clients.
Since we do not take fbdev into account when filtering modes,
we end up claiming to support more modes than we actually do.
As a result, users get a black screen when setting a mode too
large for current available memory. In a low-memory VM
configuration, users can get a black screen for a mode as low
as 1024x768.
The current mode filtering mechanism keys off of
SVGA_REG_SUGGESTED_GBOBJECT_MEM_SIZE_KB, i.e. the maximum amount
of surface memory we have. Since this value is a performance
suggestion, not a hard limit, and since there should not be much
of a performance impact for a 2D VM, rather than filtering out
more modes, we will just allow ourselves to exceed the SVGA's
performance suggestion.
Also changed assumed bpp to 32 from 16 to make sure we can
actually support all the modes listed.

On the guest kernel side, previously the FIFO has been mapped write-
combined. This has worked since VMs up to now has not honored the mapping
type and mapped the FIFO cached anyway. Since the FIFO is accessed cached
by the CPU on the virtual device side, this leads to inconsistent
mappings once the guest starts to honor the mapping types.
So ask for cached mappings when we map the FIFO. We do this by
using ioremap_cache() instead of ioremap_wc(), and remove the MTRR setup.
On the TTM side, MOBs, GMRs and VRAM buffers are already requesting
cached mappings for kernel- and user-space.

This patch fixes two issues. One, when a surface is a proxy for a DMA
buffer, it holds an extra reference that needs to be cleared.
Two, when fbdev is enabled, we need to unpin the framebuffer before
unloading the driver. This is done by a call to vmw_fb_off().
v2
Moved unreferencing surface to from vmw_framebuffer_surface_destroy()
to vmw_kms_new_framebuffer()
Added "struct vmw_framebuffer *vfb = NULL;" to silence a compiler
warning.
Removed error checking after calling vmw_surface/dmabuf_reference()

With screen targets the old legacy display system fbdev doesn't work
satisfactory anymore. At best the resolution is severely restricted.
Therefore implement fbdev on top of the kms system. With this change, fbdev
will be using whatever KMS backend is chosen.
There are helpers available for this, so in the future we'd probably want
to implement the helper callbacks instead of calling into our KMS
implementation directly.
v2: Make sure we take the mode_config mutex around modesetting,
Also clear the initial framebuffer using vzalloc instead of vmalloc.

The kernel interface is needed for fbdev, and needs to be free from
a file_priv member. To accomplish this, remove the fb surface mutex
and list which isn't used anymore, anyway.
Finally, make the pin() and unpin() pin the framebuffer for all display
system backends, so that fbdev can pin its framebuffer before mapping it.
v2: Address review comments:
- Fix vmw_framebuffer_unpin() to handle also the surface framebuffer case.
- Fix vmw_kms_new_framebuffer() to actually use the only_2d parameter.

Add command buffer support.
Currently we don't implement preemption or fancy error handling.
Tested with a couple of mesa-demos, compiz/unity and viewperf maya-03.
v2:
- Synchronize with pending work at command buffer manager takedown.
- Add an interface to flush the current command buffer for latency-critical
command batches and apply it to framebuffer dirtying.
v3:
- Minor fixes of definitions and typos to address reviews.
- Removed new or moved branch predictor hints.

This commit reworks device initialization so that we always enable the
FIFO at driver load, deferring SVGA enable until either first modeset
or fbdev enable.
This should always leave the fifo properly enabled for render- and
control nodes.
In addition,
*) We disable the use of VRAM when SVGA is not enabled.
*) We simplify PM support so that we only throw out resources on hibernate,
not on suspend, since the device keeps its state on suspend.

Final drm-misc pull for 4.0, just various things all over, including a few
more important atomic fixes. btw I didn't pick up the vmwgfx patch from
Ville's series, but one patch has one hunk touching vmwgfx and
Thomas/Jakob didn't get around to ack it. I figured it's simple enough to
be ok though.

Starting with commit b4b55cda58
("x86/PCI: Refine the way to release PCI IRQ resources")
the device lost its irq resource on module unload. While that's ok and
apparently intentional, the driver never got the resource back on module load
The code apparently wants drivers to disable the pci device at pci device
driver removal, so lets do that. That fixes the issue.

To take down the MOB and GMR memory types, the driver may have to issue
fence objects and thus make sure that the fence manager is taken down
after those memory types.

Fixes a case where we call vmw_fifo_idle() from within a wait function with
task state !TASK_RUNNING, which is illegal.
In addition, make the locking fine-grained, so that it is performed once
for every read- and write operation. This is of course more costly, but we
don't perform much register access in the timing critical paths anyway. Instead
we have the extra benefit of being sure that we don't forget the hw lock around
register accesses. I think currently the kms code was quite buggy w r t this.
