6457a0df4d drm/virtio: delete notify in virtio_gpu_object_create 
For 3D buffers, virtio_gpu_gem_object_open notifies.
We can have the same behavior for dumb buffer.

v2: virtio_gpu_gem_object_open always notifies
v3: avoid boolean variable

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]

device has an existing master. An audit of the following projects, shows
that the errno is used only for printf() purposes.

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.
