Starting with ACPI 6.2 bits 1 and 2 of the BGRT status field are no longer reserved. These bits are now used to indicate if the image needs to be rotated before being displayed. The first device using these bits has now shown up (the GPD MicroPC) and the reserved bits check causes us to reject the valid BGRT table on this device. Rather then changing the reserved bits check, allowing only the 2 new bits, instead just completely remove it so that we do not end up with a similar problem when more bits are added in the future.

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.
