Krister Johansen f95e9f7afe proc: sysctl: prevent aliased sysctls from getting passed to init ... commit 8001f49394 upstream. The code that checks for unknown boot options is unaware of the sysctl alias facility, which maps bootparams to sysctl values. If a user sets an old value that has a valid alias, a message about an invalid parameter will be printed during boot, and the parameter will get passed to init. Fix by checking for the existence of aliased parameters in the unknown boot parameter code. If an alias exists, don't return an error or pass the value to init.
