After updating to 5.4.7 we noticed that virtio_gpu's wait ioctl
stopped working correctly.
It looks like 29cf12394c05 ("drm/virtio: switch
virtio_gpu_wait_ioctl() to gem helper.") was picked up automatically,
but it depends on 889165ad6190 ("drm/virtio: pass gem reservation
object to ttm init") from earlier in Gerd's series in Linus's tree,
which was not picked up.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
