commit 44eb0cb9620c6a53ec8e7073262e2af8079b727f upstream.
VMA offsets are 64 bits. Plane surface offsets are in ggtt and
the hardware register to set this is thus 32 bits. Be explicit
about these and convert carefully to from vma to final size.
This will make sparse happy by not creating 32bit pointers out
of 64bit vma offsets.

Since SKL has universal planes, we should configure the sprite planes
and the primary plane the same. For the primary plane we do enable
the pipe gamma on the plane so do the same for the non-primary planes.
Without this, the pipe CRC values will be different for something
displayed on the primary plane and something displayed on a sprite
plane when the ARGB8888 format is used.

This is a squash of the following commits:
Revert "drm/i915: Drop intel_update_sprite_watermarks"
This reverts commit 47c99438b52d12df50e182583634a4cfede3c920.
Revert "drm/i915/ivb: Move WaCxSRDisabledForSpriteScaling w/a to atomic check"
This reverts commit 7809e5ae35b9d8d0710f0874b2e3f10be144e38b.
Revert "drm/i915/skl: Eliminate usage of pipe_wm_parameters from SKL-style WM (v3)"
This reverts commit 3a05f5e2e78eab7ffe816abb59b6769e331a1957.
With these reverts, SKL finally stops failing every single FBC test
with FIFO underrun error messages. After some brief testing, it also
seems that this commit prevents the machine from completely freezing
when we run igt/kms_fbc_crc (see fd.o #92355).

The only platform that still has an update_sprite_wm entrypoint is SKL;
on SKL, intel_update_sprite_watermarks just updates intel_plane->wm and
then performs a regular watermark update. However intel_plane->wm is
only used to update a couple fields in intel_wm_config, and those fields
are never used by the SKL code, so on SKL an update_sprite_wm is
effectively identical to an update_wm call. Since we're already
ensuring that the regular intel_update_wm is called any time we'd try to
call intel_update_sprite_watermarks, the whole call is redundant and can
be dropped.

Currently intel_gen4_compute_page_offset() simply picks the closest
page boundary below the linear offset. That however may not be suitably
aligned to satisfy any hardware specific restrictions. So let's make
sure the page boundary we choose is properly aligned.
Also to play it a bit safer lets split the remaining linear offset into
x and y values instead of just x. This should make no difference for
most platforms since we convert the x and y offsets back into a linear
offset before feeding them to the hardware. HSW+ are different however
and use x and y offsets even with linear buffers, so they might have
trouble if either the x or y get too big.

There is a mplayer video failure reported with xv.
This is because there is a request to do both plane scaling
and colorkey. Because skl hw doesn't support plane scaling
and colorkey at the same time, request is failed which is expected
behavior.
To make xv operate, this patch allows colorkey continue to work
without using scaler. Then behavior would be similar to platforms
without plane scaler support.

Switch from our plane update/disable entrypoints to use the full atomic
helpers (which generate a top-level atomic transaction) rather than the
transitional helpers (which only create/manipulate orphaned plane states
independent of a top-level transaction). Various upcoming work (SKL
scalers, atomic watermarks, etc.) requires a full atomic transaction to
behave properly/cleanly.
Last time we tried this, we had to back out the change because we still
call the drm_plane vfuncs directly from within our legacy modesetting
code. This potentially results in nested atomic transactions, locking
collisions, and other failures. To avoid that problem again, we
sidestep the issue by calling the transitional helpers directly (rather
than through a vfunc) when we're nested inside of other legacy
modesetting code. However this does allow legacy SetPlane() ioctl's to
process an entire drm_atomic_state transaction, which is important for
upcoming patches.
