Merge VT_RESIZEX fixes from Maciej Rozycki: "I got to the bottom of the issue with VT_RESIZEX recently discussed and came up with this small patch series, fixing an additional issue that I originally thought might be broken VGA hardware emulation with my laptop, which however turned out to be intertwined with the original problem and also a regression introduced somewhat later. The fix for that because the first patch, and then to make backporting feasible I had to put a revert of the offending change from last September next, followed by a proper fix for the framebuffer issue that change had tried to address. See individual change descriptions for details. These have been verified with true VGA hardware (a Trident TVGA8900 ISA video adapter) using various combinations of `svgatextmode' and `setfont' command invocations to change both the VT size and the font size, and also switching between the text console and X11, both by starting/stopping the X server and by switching between VTs. All this to ensure bringing the behaviour of VGA text console back to correct operation as it used to be with Linux 2.6.18" * emailed patches from Maciej W.

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.
