It is often useful to compare an ESR syndrome reporting the trapping of a system register with a value matching that system register. Since encoding both the sysreg and the ESR version seem to be a bit overkill, let's add a set of macros that convert an ESR value into the corresponding sysreg encoding. We handle both AArch32 and AArch64, taking advantage of identical encodings between system registers and CP15 accessors.

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.
