aa29040b43 drm/amdgpu: validate size and offset of user fence BO 
We need to validate the offset to make sure that we don't write after the BO.

Additional to that a page should be enough and can make address space

In previous drm_global_item_ref, there are two times of writing
ref->object if item->refcount is 0. So this patch does a minor update
to put alloc and init ref firstly, and then to modify the item of glob
array. Use "else" to avoid two times of writing ref->object. It can
make the code logic more clearly.

ea54ff4008 drm/i915: Ignore OpRegion panel type except on select machines 
Turns out
commit a05628195a ("drm/i915: Get panel_type from OpRegion panel
details") has regressed quite a few machines. So it looks like we
can't use the panel type from OpRegion on all systems, and yet we
absolutely must use it on some specific systems.

Despite trying, I was unable to find any automagic way to determine
if the OpRegion panel type is respectable or not. The only glimmer
of hope I had was bit 8 in the SCIC response, but that turned out to
not work either (it was always 0 on both types of systems).

So, to fix the regressions without breaking the machine we know to need
the OpRegion panel type, let's just add a quirk for this. Only specific
machines known to require the OpRegion panel type will therefore use
it. Everyone else will fall bck to the VBT panel type.

The only known machine so far is a "Conrac GmbH IX45GM2". The PCI
subsystem ID on this machine is just a generic 8086:2a42, so of no use.
Instead we'll go with a DMI match.

I suspect we can now also revert
commit aeddda06c1 ("drm/i915: Ignore panel type from OpRegion on SKL")
but let's leave that to a separate patch.

v2: Do the DMI match in the opregion code directly, as dev_priv->quirks
    gets populated too late

    drm/i915/psr: Make idle_frames sensible again

There are panels that needs 4 idle frames before entering PSR,
but VBT is unproperly set.

Also lately it was identified that idle frame count calculated at HW
can be off by 1, what makes the minimum of 2, at least.

Without the current vbt+1 we are with the risk of having HW calculating
0 idle frames and entering PSR when it shouldn't. Regardless the lack
of link training.

[Jani: there is some disagreement on the explanation, but the commit
regresses so revert it is.]

c8ebfad7a0 drm/i915: Ignore OpRegion panel type except on select machines 
Turns out
commit a05628195a ("drm/i915: Get panel_type from OpRegion panel
details") has regressed quite a few machines. So it looks like we
can't use the panel type from OpRegion on all systems, and yet we
absolutely must use it on some specific systems.

Despite trying, I was unable to find any automagic way to determine
if the OpRegion panel type is respectable or not. The only glimmer
of hope I had was bit 8 in the SCIC response, but that turned out to
not work either (it was always 0 on both types of systems).

So, to fix the regressions without breaking the machine we know to need
the OpRegion panel type, let's just add a quirk for this. Only specific
machines known to require the OpRegion panel type will therefore use
it. Everyone else will fall bck to the VBT panel type.

The only known machine so far is a "Conrac GmbH IX45GM2". The PCI
subsystem ID on this machine is just a generic 8086:2a42, so of no use.
Instead we'll go with a DMI match.

I suspect we can now also revert
commit aeddda06c1 ("drm/i915: Ignore panel type from OpRegion on SKL")
but let's leave that to a separate patch.

v2: Do the DMI match in the opregion code directly, as dev_priv->quirks
    gets populated too late
