/proc/cpuinfo shows features which the kernel supports. Some of these flags are derived from CPUID, and others are derived from other sources, including some that are entirely software-based. Currently, there is not any documentation in the kernel about how /proc/cpuinfo flags are generated and what it means when they are missing. Add documentation for /proc/cpuinfo feature flags enumeration. Document how and when x86 feature flags are used. Also discuss what their presence or absence mean for the kernel and users.
