After each CPU has been started, we iterate through a list of CPU features or bugs to detect CPUs which need (or could benefit from) kernel code patches. For each feature/bug there is a function which checks if that particular CPU is affected. We will later provide some more generic functions for common things like testing for certain MIDR ranges. We do this for every CPU to cover big.LITTLE systems properly as well. If a certain feature/bug has been detected, the capability bit will be set, so that later the call to apply_alternatives() will trigger the actual code patching.
