[ Upstream commit a483fcab38b43fb34a7f12ab1daadd3907f150e2 ] 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 ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
