read_system_reg() can readily be confused with read_sysreg(), whereas these are really quite different in their meaning. This patches attempts to reduce the ambiguity be reserving "sysreg" for the actual system register accessors. read_system_reg() is instead renamed to read_sanitised_ftr_reg(), to make it more obvious that the Linux-defined sanitised feature register cache is being accessed here, not the underlying architectural system registers. cpufeature.c's internal __raw_read_system_reg() function is renamed in line with its actual purpose: a form of read_sysreg() that indexes on (non-compiletime-constant) encoding rather than symbolic register name.

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.
