That's not how I have it currently. It's a comma-separated a string,
including the reserved name "all". The default would just be
"CONFIG_LSM_ENABLE=all". Casey and I wanted this to have a way to
capture new LSMs by default at build-time.

Okay, this is closer to v3 than v4. Paul or Stephen, how do you feel
about losing the SELinux bootparam CONFIG? (i.e. CONFIG_LSM_ENABLE
would be replacing its functionality.)
