Atomic modesetting code lacked support for specifying mouse cursor hotspots. The legacy kms DRM_IOCTL_MODE_CURSOR2 had support for setting the hotspot but the functionality was not implemented in the new atomic paths. Due to the lack of hotspots in the atomic paths userspace compositors completely disable atomic modesetting for drivers that require it (i.e. all paravirtualized drivers). This change adds hotspot properties to the atomic codepaths throughtout the DRM core and will allow enabling atomic modesetting for virtualized drivers in the userspace.

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.
