The backward compatibility register (BCR) has a set of bit flags that indicate ways in which the IPA hardware should operate in a backward compatible way. The register is not supported starting with IPA v4.5, and where it is supported, defined bits all have the same numeric value. Redefine these flags using an enumerated type, with each member's value representing the bit position that encodes it in the BCR. This replaces all of the single-bit field masks previously defined.

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.
