commit dd2b75fd9a79bf418e088656822af06fc253dbe3 upstream.

This reverts commit 28ebbb4981cb1fad12e0b1227dbecc88810b1ee8.

Revert this commit as apparently the LLVM code to take advantage of
this never landed.

commit 267cace556e8a53d703119f7435ab556209e5b6a upstream.

commit cd94d1b182d2 ("dm/amd/pm: Fix problems with reboot/shutdown for
some SMU 13.0.4/13.0.11 users") attempted to fix shutdown issues
that were reported since commit 31729e8c21ec ("drm/amd/pm: fixes a
random hang in S4 for SMU v13.0.4/11") but caused issues for some
people.

Adjust the workaround flow to properly only apply in the S4 case:
-&gt; For shutdown go through SMU_MSG_PrepareMp1ForUnload
-&gt; For S4 go through SMU_MSG_GfxDeviceDriverReset and
   SMU_MSG_PrepareMp1ForUnload

commit e64e8f7c178e5228e0b2dbb504b9dc75953a319f upstream.

[Why]
The vram width value is 0.
Because the integratedsysteminfo table in VBIOS has updated to 2.3.

[How]
Driver needs a new intergrated info v2.3 table too.
Then the vram width value will be correct.

commit 87cb4a612a89690b123e68f6602d9f6581b03597 upstream.

Framebuffer memory is allocated via vzalloc() from non-contiguous
physical pages. The physical framebuffer start address is therefore
meaningless. Do not set it.

The value is not used within the kernel and only exported to userspace
on dedicated ARM configs. No functional change is expected.

v2:
- refer to vzalloc() in commit message (Javier)

commit 1008368e1c7e36bdec01b3cce1e76606dc3ad46f upstream.

The queue width will determine the number of batch buffer emitted into
the ring. In the case of xe_bb_create_job() we pass exactly one batch
address, therefore add an assert for the width to make sure we don't go
out of bounds. While here also convert to the helper to determine if the
queue is migration based.

<title>drm/i915/hwmon: Get rid of devm</title>

commit 5bc9de065b8bb9b8dd8799ecb4592d0403b54281 upstream.

When both hwmon and hwmon drvdata (on which hwmon depends) are device
managed resources, the expectation, on device unbind, is that hwmon will be
released before drvdata. However, in i915 there are two separate code
paths, which both release either drvdata or hwmon and either can be
released before the other. These code paths (for device unbind) are as
follows (see also the bug referenced below):

Call Trace:
release_nodes+0x11/0x70
devres_release_group+0xb2/0x110
component_unbind_all+0x8d/0xa0
component_del+0xa5/0x140

and

device_unbind_cleanup+0x9/0x70
device_release_driver_internal+0x1c1/0x200
unbind_store+0x9c/0xb0

This means that in i915, if use devm, we cannot gurantee that hwmon will
always be released before drvdata. Which means that we have a uaf if hwmon
sysfs is accessed when drvdata has been released but hwmon hasn't.

The only way out of this seems to be do get rid of devm_ and release/free
everything explicitly during device unbind.

v2: Change commit message and other minor code changes
v3: Cleanup from i915_hwmon_register on error (Armin Wolf)
v4: Eliminate potential static analyzer warning (Rodrigo)
    Eliminate fetch_and_zero (Jani)
v5: Restore previous logic for ddat_gt-&gt;hwmon_dev error return (Andi)

commit 2a705f3e49d20b59cd9e5cc3061b2d92ebe1e5f0 upstream.

Observed on gfx8 ASIC where KFD_IOC_ALLOC_MEM_FLAGS_AQL_QUEUE_MEM is used.
Two attachments use the same VM, root PD would be locked twice.

<title>Revert "drm: Make drivers depends on DRM_DW_HDMI"</title>

commit 8f7f115596d3dccedc06f5813e0269734f5cc534 upstream.

This reverts commit c0e0f139354c01e0213204e4a96e7076e5a3e396, as helper
code should always be selected by the driver that needs it, for the
convenience of the final user configuring a kernel.

The user who configures a kernel should not need to know which helpers
are needed for the driver he is interested in.  Making a driver depend
on helper code means that the user needs to know which helpers to enable
first, which is very user-unfriendly.
