Use vma_lookup() to find the VMA at a specific address. As vma_lookup()
will return NULL if the address is not within any VMA, the start address
no longer needs to be validated.

vma_lookup() will look up the vma at a specific address. find_vma() will
start the search for a specific address and continue upwards. This fixes
an issue with the selftest as the returned vma may not be the newly
created vma, but simply the vma at a higher address.

For KMS drivers, replace the IRQ check in VBLANK ioctls with a check for
vblank support. IRQs might be enabled wthout vblanking being supported.
This change also removes the DRM framework's only dependency on IRQ state
for non-legacy drivers. For legacy drivers with userspace modesetting,
the original test remains in drm_wait_vblank_ioctl().

Failing to read the MTP over DSI should not bring down the
system and make us bail out from using the display, it turns
out that this happens when toggling the display off and on,
and that write is often still working so the display output
is just fine. Printing an error is enough.
Tested by killing the Gnome session repeatedly on the
Samsung Skomer.

Reinstate the mmap ioctl for all current integrated platforms.
The intention was really to have it disabled for discrete graphics
where we enforce a single mmap mode.
This was reported to break ADL-P with the media stack, which was not the
intention. Although longer term we do still plan to sunset this ioctl
even for integrated, in favour of using mmap_offset instead.

Add a single point of truth for figuring out the primary/secondary crtc
for bigjoiner instead of duplicating the magic pipe +/- 1 in multiple
places.
Also fix the pipe validity checks to properly take non-contiguous pipes
into account. The current checks may theoretically overflow
i915->pipe_to_crtc_mapping[pipe], albeit with a warning, due to fused
off pipes, as INTEL_NUM_PIPES() returns the actual number of pipes on
the platform, and the check is for INTEL_NUM_PIPES() == pipe + 1.
Prefer primary/secondary terminology going forward.
v2:
- Improved abstractions for pipe validity etc.

The panfrost driver tries to kill in-flight jobs on FD close after
destroying the FD scheduler entities. For this to work properly, we
need to make sure the jobs popped from the scheduler entities have
been queued at the HW level before declaring the entity idle, otherwise
we might iterate over a list that doesn't contain those jobs.

Since we are already loop through the levels to sanitize them, mark what
is the real max_level so it can be used in subsequent loop. This makes
it simpler to later add the adjustment latency to "valid levels". No
change in behavior, just makes the code easier to follow.

We should no longer increment level 0 by 1usec when we have 16Gb DIMMs.
Instead spec says to add 3usec (as opposed to 2) to each valid level
when punit replies 0 to level 0.
So set wm_lv_0_adjust_needed to false for DISPLAY_VER() >= 12 and set
the proper adjustment value when handling WaWmMemoryReadLatency.

Reinstate the mmap ioctl for all current integrated platforms.
The intention was really to have it disabled for discrete graphics
where we enforce a single mmap mode.
This was reported to break ADL-P with the media stack, which was not the
intention. Although longer term we do still plan to sunset this ioctl
even for integrated, in favour of using mmap_offset instead.

PSR2 is not compatible with DC3CO or VRR in this stepping, so not
enabling PSR2 if VRR will be enabled or not enabling DC3CO if PSR2 is
possible.

In some modes there is not enough time during hblank to transmit PSR2
SDP plus the pixels CRC SDP, if such case happens PSR2 needs to be
disabled.
But eDP spec 1.4b allows to transmit PSR2 SDP in a prior scanline
alone and than later the CRC SDP, allowing PSR2 to be enabled in
those hblank constrained modes.

expected in pre production hardware, so here adding a table that
matches with HW to program it with values that HW expect.

We were only handling X and width granularity, what was causing issues
when sink had a granularity different than 4.
While at it, renaming su_x_granularity to su_w_granularity to better
match reality.
