Add a few new SSE/AVX/AVX512 instruction groups/features for enumeration in /proc/cpuinfo: AVX512_VBMI2, GFNI, VAES, VPCLMULQDQ, AVX512_VNNI, AVX512_BITALG. CPUID.(EAX=7,ECX=0):ECX[bit 6] AVX512_VBMI2 CPUID.(EAX=7,ECX=0):ECX[bit 8] GFNI CPUID.(EAX=7,ECX=0):ECX[bit 9] VAES CPUID.(EAX=7,ECX=0):ECX[bit 10] VPCLMULQDQ CPUID.(EAX=7,ECX=0):ECX[bit 11] AVX512_VNNI CPUID.(EAX=7,ECX=0):ECX[bit 12] AVX512_BITALG Detailed information of CPUID bits for these features can be found in the Intel Architecture Instruction Set Extensions and Future Features Programming Interface document (refer to Table 1-1. and Table 1-2.).

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.
