This patch adds the hook for emulating MRS instruction to export the 'user visible' value of supported system registers. We emulate only the following id space for system registers: Op0=3, Op1=0, CRn=0, CRm=[0, 4-7] The rest will fall back to SIGILL. This capability is also advertised via a new HWCAP_CPUID.

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.
