Merge drm/drm-next into drm-misc-next
We haven't done any backmerge for a while due to the merge window, and it
starts to become an issue for komeda. Let's bring 5.4-rc1 in.

293f86b365 drm/vmwgfx: switch to own vma manager
Add struct drm_vma_offset_manager to vma_private, initialize it and
pass it to ttm_bo_device_init().

With this in place the last user of ttm's embedded vma offset manager
is gone and we can remove it (in a separate patch).

9d6f4484e8 drm/ttm: turn ttm_bo_device.vma_manager into a pointer
Rename the embedded struct vma_offset_manager, new name is _vma_manager.
ttm_bo_device.vma_manager changed to a pointer.

The ttm_bo_device_init() function gets an additional vma_manager
argument which allows to initialize ttm with a different vma manager.
When passing NULL the embedded _vma_manager is used.

All callers are updated to pass NULL, so the behavior doesn't change.

Drop use of the deprecated drmP.h file from the
remaining files.
In several cases the drmP.h include could be removed without
furter fixes. Other files required a few header files to be added.

9c84aeba67 drm/vmwgfx: Kill unneeded legacy security features
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.

Pull drm updates from Dave Airlie:
 "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.

  There are also some rcar-du patches which crossover with media tree
  but all should be acked by Mauro.

   - 64-bit dma-fence seqno comparison fixes
   - move initial fb config code to core
   - gem fence array helpers for Lima
   - ability to remove legacy support code if no drivers requires it (removes 10% of drm.ko size)
   - lease fixes

  ttm:
   - unified DRM_FILE_PAGE_OFFSET handling
   - Account for kernel allocations in kernel zone only

81103355b1 drm/vmwgfx: Fix dma API layer violation
Remove the check for IOMMU presence since it was considered a
layer violation.
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.

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).

5b38e7475e drm/irq: Don't check for DRIVER_HAVE_IRQ in drm_irq_(un)install
If a non-legacy driver calls these it's valid to assume there is
interrupt support. The flag is really only needed for legacy drivers,
which control IRQ enabling/disabling through the DRM_IOCTL_CONTROL
legacy IOCTL.

Also remove all the flag usage from non-legacy drivers.

v2: Review from Emil:
- improve commit message
- I forgot hibmc, fix that

2b3cd6249b drm/vmwgfx: fix the check when to use dma_alloc_coherent
Since Linux 4.21 we merged the swiotlb ops into the DMA direct ops,
so they would always have a the sync_single methods.  But late in
the cicle we also removed the direct ops entirely, so we'd see NULL
DMA ops.  Switch vmw_dma_select_mode to only detect swiotlb presence
using swiotlb_nr_tbl() instead.

af7ddd8a62 DMA mapping updates for Linux 4.21
A huge update this time, but a lot of that is just consolidating or
 removing code:
 
  - provide a common DMA_MAPPING_ERROR definition and avoid indirect
    calls for dma_map_* error checking
  - use direct calls for the DMA direct mapping case, avoiding huge
    retpoline overhead for high performance workloads
  - merge the swiotlb dma_map_ops into dma-direct
  - provide a generic remapping DMA consistent allocator for architectures
    that have devices that perform DMA that is not cache coherent. Based
    on the existing arm64 implementation and also used for csky now.
  - improve the dma-debug infrastructure, including dynamic allocation
    of entries (Robin Murphy)
  - default to providing chaining scatterlist everywhere, with opt-outs
    for the few architectures (alpha, parisc, most arm32 variants) that
    can't cope with it
  - misc sparc32 dma-related cleanups
  - remove the dma_mark_clean arch hook used by swiotlb on ia64 and
    replace it with the generic noncoherent infrastructure
  - fix the return type of dma_set_max_seg_size (Niklas Söderlund)
  - move the dummy dma ops for not DMA capable devices from arm64 to
    common code (Robin Murphy)
  - ensure dma_alloc_coherent returns zeroed memory to avoid kernel data
    leaks through userspace.  We already did this for most common
    architectures, but this ensures we do it everywhere.
    dma_zalloc_coherent has been deprecated and can hopefully be
    removed after -rc1 with a coccinelle script.

27eb1fa913 drm/ttm: use a static ttm_mem_global instance
As the name says we only need one global instance of ttm_mem_global.

Drop all the driver initialization and just use a single exported
instance which is initialized during BO global initialization.

13289241fe drm/vmwgfx: Remove the resource avail field
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.

f1d34bfd70 drm/vmwgfx: Replace vmw_dma_buffer with vmw_buffer_object
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.

6a93cea15e drm/vmwgfx: Schedule an fb dirty update after resume
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.
