GEN9 onwards bypass path allocation of 4 blocks was needed, as per
hardware design. ICL doesn't require bypass path allocation of 4 DDB
blocks, handling the same in this patch.
v2 (from Paulo):

This is a precautionary measure as I have no evidence to suggest we've
hit a bug here (I was hoping this might explain gdg's odd behaviour, but
alas), but given that we have a function to flush the ggtt writes it
seems prudent to use it prior to changing the fence register. Due to the
intrinsic nature of the GTT often operating as an independent mmio path,
we should not just rely on the write to the fence acting as a full flush
for GTT writes.

Previously, we relied on only running the hangcheck while somebody was
waiting on the GPU, in order to minimise the amount of time hangcheck
had to run. (If nobody was watching the GPU, nobody would notice if the
GPU wasn't responding -- eventually somebody would care and so kick
hangcheck into action.) However, this falls apart from around commit
4680816be336 ("drm/i915: Wait first for submission, before waiting for
request completion"), as not all waiters declare themselves to hangcheck
and so we could switch off hangcheck and miss GPU hangs even when
waiting under the struct_mutex.
If we enable hangcheck from the first request submission, and let it run
until the GPU is idle again, we forgo all the complexity involved with
only enabling around waiters. We just have to remember to be careful that
we do not declare a GPU hang when idly waiting for the next request to
be come ready, as we will run hangcheck continuously even when the
engines are stalled waiting for external events. This should be true
already as we should only be tracking requests submitted to hardware for
execution as an indicator that the engine is busy.

Pull poll annotations from Al Viro:
"This introduces a __bitwise type for POLL### bitmap, and propagates
the annotations through the tree. Most of that stuff is as simple as
'make ->poll() instances return __poll_t and do the same to local
variables used to hold the future return value'.
Some of the obvious brainos found in process are fixed (e.g. POLLIN
misspelled as POLL_IN). At that point the amount of sparse warnings is
low and most of them are for genuine bugs - e.g. ->poll() instance
deciding to return -EINVAL instead of a bitmap. I hadn't touched those
in this series - it's large enough as it is.
Another problem it has caught was eventpoll() ABI mess; select.c and
eventpoll.c assumed that corresponding POLL### and EPOLL### were
equal. That's true for some, but not all of them - EPOLL### are
arch-independent, but POLL### are not.
The last commit in this series separates userland POLL### values from
the (now arch-independent) kernel-side ones, converting between them
in the few places where they are copied to/from userland. AFAICS, this
is the least disruptive fix preserving poll(2) ABI and making epoll()
work on all architectures.
As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and
it will trigger only on what would've triggered EPOLLWRBAND on other
architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered
at all on sparc. With this patch they should work consistently on all
architectures"

But since SKUs differences don't matter on the platform
definition group and ids, let's merge all off them together.

v6: Unify in a way that we don't break early-quirks.c
v7: Remove GT reference since it doesn't matter here (Paulo)

drm_encoder_slave is the old way to write bridge drivers, for i2c
bridges only. It's deprecated, and definitely should not be used in
new drivers. This has absolutely nothing to do with the new bridge
driver infrastructure implemented by drm_bridge.
What's even strange is that arcpgu doesn't even use any of this, it
really only wants a plain normal drm_encoder. Nuke all the surplus
real estate.

the one described in Display WA #1175. In this case, similarly for
planes other than the cursor, with 1 or 3 pixels visible from the left
edge of the screen to the end of the plane and an odd plane X offset
used for clipping causes the same kind of underflow and display
corruption as described for WA #1175. Fix this in a similar way as that

As described in the WA on GLK and CNL planes on the right edge of the
screen that have less than 4 pixels visible from the beginning of the
plane to the edge of the screen can cause FIFO underflow and display
corruption.
On GLK/CNL I could trigger the problem only if the plane was at the same
time also aligned to the top edge of the screen (after clipping) and
there were exactly 2 pixels visible from the start of the plane to the
right edge of the screen (so couldn't trigger it with 1 or 3 pixels
visible). Nevertheless, to be sure, I also applied the WA for these cases.
I also couldn't see any problem with the cursor plane and later Art
confirmed that it's not affected, so the WA is applied only for the
other plane types.

During a non-blocking commit, it is possible to return before the
commit_tail work is queued (-ERESTARTSYS, for example).
Since a reference on the crtc commit object is obtained for the pending
vblank event when preparing the commit, the above situation will leave
us with an extra reference.
Therefore, if the commit_tail worker has not consumed the event at the
end of a commit, release it's reference.
Changes since v1:
- Also check for state->event->base.completion being set, to
handle the case where stall_checks() fails in setup_crtc_commit().
Changes since v2:
- Add a flag to drm_crtc_commit, to prevent dereferencing a freed event.
i915 may unreference the state in a worker.

If the table result is out of bounds on the array map
there is something really wrong with VBT pin so we don't
return that vbt_pin, but only return 0 instead.
This basically reverts commit 'a8e6f3888b05 ("drm/i915/cnp:
Ignore VBT request for know invalid DDC pin.")'
Also this properly fixes commit 9c3b2689d01f ("drm/i915/cnl:

We never support certain mode flags etc. Reject those early on in the
mode_config.mode_valid() hook. That allows us to remove some duplicated
checks from the connector .mode_valid() hooks, and it guarantees that
we never see those flags even from user mode as the
mode_config.mode_valid() hooks gets executed for those as well.

Allow drivers to provide a device wide .mode_valid() hook in addition to
the already existing crtc/encoder/bridge/connector hooks. This can be
used to validate device/driver wide constraings without having to add
those to the other hooks. And since we call this hook also for user
modes later on in the modeset we don't have to worry about anything the
hook has already rejected.
I also have some further ideas for this hook. Eg. we could replace the
drm_mode_set_crtcinfo(HALVE_V) call in drm_mode_convert_umode()/etc.
with a driver specific variant via this hook. At least on i915 we would
like to pass CRTC_STEREO_DOUBLE to that function instead, and then
we could safely use the crtc_ timings in all our .mode_valid() hooks,
which would allow us to reuse those hooks for validating the
adjusted_mode during a modeset.

For some reason drm_mode_set_crtcinfo() does nothing if the mode has
the DRM_MODE_TYPE_BUILTIN flag set without the other bit from
DRM_MODE_TYPE_CRTC_C also set. I have zero idea what that is supposed
to achieve, but since we have no users for neither flag bit let's kill
this nonsense off.

We use 32bit bitmasks to track planes/crtcs/encoders/connectors.
Naturally we can only do that if the index of those objects stays
below 32. Issue a warning whenever we exceed that limit, hopefully
prompting someone to fix the problem.
For connectors the issue is a bit more complicated as they can
be created/destroyed at runtime due to MST. So the problem is no
longer a purely theoretical programmer error. As the connector
indexes are allocated via ida, we can simply limit the maximum
value the ida is allowed to hand out. The error handling is already
in place.

Our various planes have a configurable zpos, that combined with the pipes
allow to configure the composition.
Since the interaction between the pipes, zpos and alphas framebuffers is
not trivial, let's just enable the zpos as an immutable property for now,
and use that zpos in our atomic_update part.

However, this is not the case during the probe, and we therefore need to
