80e5f89da3 drm/qxl: Use correct notify port address when creating cursor ring 
The command ring and cursor ring use different notify port addresses
definition: QXL_IO_NOTIFY_CMD and QXL_IO_NOTIFY_CURSOR. However, in
qxl_device_init() we use QXL_IO_NOTIFY_CMD to create both command ring
and cursor ring. This doesn't cause any problems now, because QEMU's
behaviors on QXL_IO_NOTIFY_CMD and QXL_IO_NOTIFY_CURSOR are the same.
However, QEMU's behavior may be change in future, so let's fix it.

P.S.: In the X.org QXL driver, the notify port address of cursor ring
      is correct.

c7da606eda drm/managed: Fix off-by-one in warning 
I'm thinking this is the warning that fired in the 0day report, but I
can't double-check yet since 0day didn't upload its source tree
anywhere I can check. And all the drivers I can easily test don't use
drm_dev_alloc anymore ...

Also if I'm correct supreme amounts of bad luck because usually kslap
(for bigger structures) gives us something quite a bit bigger than
what we asked for.

[0day uploaded tree, guess is correct]

45bc3d26c9 drm: rework SET_MASTER and DROP_MASTER perm handling 
This commit reworks the permission handling of the two ioctls. In
particular it enforced the CAP_SYS_ADMIN check only, if:
 - we're issuing the ioctl from process other than the one which opened
the node, and
 - we are, or were master in the past

This ensures that we:
 - do not regress the systemd-logind style of DRM_MASTER arbitrator
 - allow applications which do not use systemd-logind to drop their
master capabilities (and regain them at later point) ... w/o running as
root.

See the comment above drm_master_check_perm() for more details.

v1:
 - Tweak wording, fixup all checks, add igt test

v2:
 - Add a few more comments, grammar nitpicks.

105235e4ae drm: panel: Add Starry KR070PE2T 
The KR070PE2T is a 7" panel with a resolution of 800x480.

KR070PE2T is the marking present on the ribbon cable. As this panel is
probably available under different brands, this marking will catch
most devices.

As I can't find a datasheet for this panel, the bus_flags are instead
from trial-and-error. The flags seem to be common for these kind of
panels as well.

1996970773 drm/lima: Add optional devfreq and cooling device support 
Most platforms with a Mali-400 or Mali-450 GPU also have support for
changing the GPU clock frequency. Add devfreq support so the GPU clock
rate is updated based on the actual GPU usage when the
"operating-points-v2" property is present in the board.dts.

The actual devfreq code is taken from panfrost_devfreq.c and modified so
it matches what the lima hardware needs:
- a call to dev_pm_opp_set_clkname() during initialization because there
  are two clocks on Mali-4x0 IPs. "core" is the one that actually clocks
  the GPU so we need to control it using devfreq.
- locking when reading or writing the devfreq statistics because (unlike
  than panfrost) we have multiple PP and GP IRQs which may finish jobs
  concurrently.

6bb0942e8f drm/dp_mst: Remove single tx msg restriction. 
Now that we can support multiple simultaneous replies, remove the
restrictions placed on sending new tx msgs.

This patch essentially just reverts commit
  5a64967a2f ("drm/dp_mst: Have DP_Tx send one msg at a time")
now that the problem is solved in a different way.

fbc821c4a5 drm/mst: Support simultaneous down replies 
Currently we have one down reply message servicing the mst manager, so
we need to serialize all tx msgs to ensure we only have one message in
flight at a time. For obvious reasons this is suboptimal (but less
suboptimal than the free-for-all we had before serialization).

This patch removes the single down_rep_recv message from manager and
adds 2 replies in the branch structure. The 2 replies mirrors the tx_slots
which we use to rate-limit outgoing messages and correspond to seqno in
the packet headers.

1a8bf67df6 drm/fb-helper: Add TODO for making drm_fb_helper_alloc_fbi fill apertures 
Currently drivers using drm_fbdev_generic_setup() end up with a single
empty aperture in their fb_info struct.

Not having the proper info in the apertures list causes
register_framebuffer to not remove conflicting framebuffers,
which some drivers currently workaround by manually calling
drm_fb_helper_remove_conflicting_pci_framebuffers().

Add a TODO as a reminder that we need to fix this.
