From: Kees Cook <redacted> In preparation for removing CONFIG_DEFAULT_SECURITY, this removes the soon-to-be redundant SECURITY_SELINUX_BOOTPARAM_VALUE. Since explicit ordering via CONFIG_LSM or "lsm=" will define whether an LSM is enabled or not, this CONFIG will become effectively ignored, so remove it. However, in order to stay backward-compatible with "security=selinux", the enable variable defaults to true.
