When setting a mode we not only pass the mode to the hypervisor, but also information on how to map / translate input coordinates for the emulated USB tablet. This input-mapping may change when the mode on *another* crtc changes. This means that sometimes we must do a modeset on other crtc-s then the one being changed to update the input-mapping. Including crtc-s which may be disabled inside the guest (shown as a black window on the host unless closed by the user). With atomic modesetting the mode-info of disabled crtcs gets zeroed yet we need it when updating the input-map to avoid resizing the window as a side effect of a mode_set on another crtc. This commit adds caching of the mode info into out private vbox_crtc struct so that we always have the info at hand when we need it.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
