Previously we assumed two 4-byte writes to the same PTE coming in sequence.
But recently we observed inconsecutive partial write happening as well. So
this patch enhances the previous solution. It now uses a list to save more
partial writes. If one partial write can be combined with another one in
the list to construct a full PTE, update its shadow entry. Otherwise, save
the partial write in the list.

commit ac657f6461 ("drm/i915: Introduce IS_GEN macro") introduced
GEN_FOREVER that was never used.
My first attempt was to rename it to FOREVER since GEN is
already part of the macro. Then I used coccinelle to change all
-INTEL_GEN(e1) >= e2
+INTEL_GEN_RANGE(e1, e2, FOREVER)
-INTEL_GEN(e1) <= e2
+INTEL_GEN_RANGE(e1, 0, e2)
and I liked it.
However I didn't like very much the remaining
INTEL_GEN(dev_priv) < n
and:
INTEL_GEN(e1) < n
INTEL_GEN_RANGE(e1, 0, n - 1)
didn't make much sense either.
So INTEL_GEN use for > or < seems a better unified way for unlimited
bounds. So, no reason to keep GEN_FOREVER here.
Let's kill before someone start using it.
v2: Remove remaining GEN_FOREVER forgotten in a comment. (Daniel)

1. Introduces the XArray implementation
2. Converts the pagecache to use it
3. Converts memremap to use it
The page cache is the most complex and important user of the radix
tree, so converting it was most important. Converting the memremap
code removes the only other user of the multiorder code, which allows
us to remove the radix tree code that supported it.
I have 40+ followup patches to convert many other users of the radix
tree over to the XArray, but I'd like to get this part in first. The
other conversions haven't been in linux-next and aren't suitable for

HDMI 2.0 monitors may not support SCDC and still be able to accept VICs
above 63. Use multiple EDID capbilities to determine if the SINK is
actually an HDMI 2.0 device. The QD980B HDMI 2.0 Analyzer generates unique
EDIDs during CTS tests that don't contain a HDMI Forum VSDB if the block is
not used during the test. The current HDMI AVI infoframe code only uses the
SCDC supported information in the HDMI Forum VSDB to determine if the sink
is HDMI 2.0. This patch adds a check for YCbCr420 present in the EDID
supported formats as well as the existing SCDC supported check.

In order to ensure that our system suspend and resume callbacks are
called in the correct order wrt. those of the HDA driver add a device
link to the HDA driver during audio component binding time. With i915 as
the supplier and HDA as the consumer the PM framework will guarantee
the HDA->i915 suspend (and shutdown) and i915->HDA resume order.
Atm, the lack of this ordering is not a problem, since all the i915
suspend/resume steps that need to be ordered wrt. the HDA driver's
suspend/resume steps are separated out to the i915
suspend_late/resume_early hooks. That will change in a follow-up
patchset where we'll need this ordering guarantee for steps that are in
the i915 suspend/resume hooks (and which can't be moved to
suspend_late/resume_early for other reasons). So this patch is a
preparation for that follow-up patchset.
The change also allows us to move towards removing the i915
suspend_late/resume_early hooks alltogether.
Since we only need to ensure the ordering during suspend/resume and not
during driver probing create the link with DL_FLAG_STATELESS. Since the
probe time ordering has to be optional we use the component framework
for that.
Similarly for runtime PM we depend on the audio driver getting/putting
an i915 runtime PM reference whenever it needs it (along with the proper
i915 display power domain) via the audio component ops get_power /
put_power hooks. So we create the device link without
DL_FLAG_PM_RUNTIME.
v2: (Ville)
- Add a note to the commit message about not using the device link
runtime PM ordering.
- Handle the error return from device_link_add().

Comment claims link needs to be retrained because the connected sink raised
a long pulse to indicate link loss. If the sink did so,
intel_dp_hotplug() would have handled link retraining. Looking at the
logs in Bugzilla referenced in commit '3cf71bc9904d ("drm/i915: Re-apply
Perform link quality check, unconditionally during long pulse"")', the
issue is that the sink does not trigger an interrupt. What we want is
->detect() from user space to check link status and retrain. Ville's
review for the original patch also indicates the same root cause. So,
rewrite the comment.

The first 3 planes (primary, sprite 0 and 1) have a dedicated chroma
upsampler to upscale YUV420 to YUV444 and the scaler should only be
used for upscaling. Because of this we shouldn't program the scalers
in planar mode if NV12 and the chroma upsampler are used. Instead
program the scalers like on normal planes.

To make NV12 working on icl, we need to update 2 planes simultaneously.
I've chosen to do this in the CRTC step after plane validation is done,
so we know what planes are (in)visible. The linked Y plane will get
updated in intel_plane_update_planes_on_crtc(), by the call to
update_slave, which gets the master's plane_state as argument.
The link requires both planes for atomic_update to work,
so make sure skl_ddb_add_affected_planes() adds both states.
Changes since v1:
- Introduce icl_is_nv12_y_plane(), instead of hardcoding sprite numbers.
- Put all the state updating login in intel_plane_atomic_check_with_state().
- Clean up changes in intel_plane_atomic_check().
Changes since v2:
- Fix intel_atomic_get_old_plane_state() to actually return old state.

it's a cleaner way to do this. (Ville)
