In some cases, core variants that are affected by a certain erratum also exist in versions that have the erratum fixed, and this fact is recorded in a dedicated bit in system register REVIDR_EL1. Since the architecture does not require that a certain bit retains its meaning across different variants of the same model, each such REVIDR bit is tightly coupled to a certain revision/variant value, and so we need a list of revidr_mask/midr pairs to carry this information. So add the struct member and the associated macros and handling to allow REVIDR fixes to be taken into account.

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.
