actually have one.

commit 3bcf603f6d5d18bd9d076dc280de71f48add4101 upstream.
On CougarPoint and PantherPoint PCH chips, the timing generator may fail
to start after DP training completes. This is due to a bug in the
FDI autotraining detect logic (which will stall the timing generator and
re-enable it once training completes), so disable it to avoid silent DP
mode setting failures.

commit 082918471139b07964967cfe5f70230909c82ae1 upstream.
radeon_i2c_fini() walks thru the list of I2C bus recs rdev->i2c_bus[]
to destroy each of them.
radeon_ext_tmds_enc_destroy() however also has code to destroy it's
associated I2C bus rec which has been obtained by radeon_i2c_lookup()
and is therefore also in the i2c_bus[] list.
This causes a double free resulting in a kernel panic when unloading
the radeon driver.
Removing destroy code from radeon_ext_tmds_enc_destroy() fixes this
problem.

commit b98b60167279df3acac9422c3c9820d9ebbcf9fb upstream.
Clear Audio Enable bit to trigger unsolicated event to notify Audio
Driver part the HDMI hot plug change. The patch fixed the bug when
remove HDMI cable the bit was not cleared correctly.
In intel_hdmi_dpms(), if intel_hdmi->has_audio been true, the "Audio enable bit" will
be set to trigger unsolicated event to notify Alsa driver the change.
intel_hdmi->has_audio will be reset to false from intel_hdmi_detect() after
remove the hdmi cable, here's debug log:
[ 187.494153] [drm:output_poll_execute], [CONNECTOR:17:HDMI-A-1] status updated from 1 to 2
[ 187.525349] [drm:intel_hdmi_detect], HDMI: has_audio = 0
so when comes back to intel_hdmi_dpms(), the "Audio enable bit" will not be cleared. And this
cause the eld infomation and pin presence doesnot update accordingly in alsa driver side.
This patch will also trigger unsolicated event to alsa driver to notify the hot plug event:
[ 187.853159] ALSA sound/pci/hda/patch_hdmi.c:772 HDMI hot plug event: Codec=3 Pin=5 Presence_Detect=0 ELD_Valid=1

commit 81ee8fb6b52ec69eeed37fe7943446af1dccecc5 upstream.
It seems we can not update the crtc scanout address. After disabling
crtc, update to base address do not take effect after crtc being
reenable leading to at least frame being scanout from the old crtc
base address. Disabling crtc display request lead to same behavior.
So after changing the vram address if we don't keep crtc disabled
we will have the GPU trying to read some random system memory address
with some iommu this will broke the crtc engine and will lead to
broken display and iommu error message.
So to avoid this, disable crtc. For flicker less boot we will need
to avoid moving the vram start address.
This patch should also fix :

commit 0d8957c8a90bbb5d34fab9a304459448a5131e06 upstream.
We may only start to set up the new register values after having
confirmed that the ring is truely off. Otherwise the hw might lose the
newly written register values. This is caught later on in the init
sequence, when we check whether the register writes have stuck.

commit ca2ccde5e2f24a792caa4cca919fc5c6f65d1887 upstream.
To have DP behave like VGA/DVI we need to retrain the link
on hotplug. For this to happen we need to force link
training to happen by setting connector dpms to off
before asking it turning it on again.

for now. We still need the dpms OFF change.

No need to retrain the link for passive adapters.
v2: agd5f
- no passive DP to VGA adapters, update comments
- assign radeon_connector_atom_dig after we are sure
we have a digital connector as analog connectors
have different private data.
- get new sink type before checking for retrain. No
need to check if it's no longer a DP connection.

We want to print link status query failed only if it's
an unexepected fail. If we query to see if we need
link training it might be because there is nothing
connected and thus link status query have the right
to fail in that case.
To avoid printing failure when it's expected, move the
failure message to proper place.

commit f60ec4c7df043df81e62891ac45383d012afe0da upstream.
This could previously fail if either of the enabled displays was using a
horizontal resolution that is a multiple of 128, and only the leftmost column
of the cursor was (supposed to be) visible at the right edge of that display.
The solution is to move the cursor one pixel to the left in that case.

commit 9bd0c15fcfb42f6245447c53347d65ad9e72080b upstream.
nv_two_heads() was never meant to be used outside of pre-nv50 code. The
code checks for >= NV_10 for 2 CRTCs, then downgrades a few specific
chipsets to 1 CRTC based on (pci_device & 0x0ff0).
The breakage example seen is on GTX 560Ti, with a pciid of 0x1200, which
gets detected as an NV20 (0x020x) with 1 CRTC by nv_two_heads(), causing
memory corruption because there's actually 2 CRTCs..
This switches fbcon to use the CRTC count directly from the mode_config
structure, which will also fix the same issue on Kepler boards which have
4 CRTCs.

When page tables would normally be freed, leak them instead.
This experiment is to try to prove a distinction between a use-after-free
type bug and another driver corrupting our page tables. At the point the
asserts go off, we don't expect the page to have been freed yet. So it
should contain only valid PTEs. If however the PT is being used after
free, it might contain junk from other kernel drivers. If we don't free
the PTs, the latter should never happen.

DumpPT already had a static inline if PT_DEBUG or PT_DUMP
weren't defined, so it shouldn't have been #ifdef guarded.
Furthermore, PT_DEBUG isn't enabled so DumpPT would not have been
called to dump the page tables in one case. This is incorrect as
it should have been called if PT_DUMP was enabled.

The SGX MMU code was not designed to be used from multiple driver
threads. One theory is that somehow the driver does sometimes use
the MMU code from multiple threads, which could cause corruption
of meta data.
We must allow PID 1 through because the kernel uses this ID before
userspace is up, and the module_init code interacts with the MMU
subsystem.
Otherwise, check that the outer bridge lock is held. If it is held,
check the PID of the caller matches the PID holding the bridge lock.
