To check two strings for equality, the result from strcmp must be
negated. Without the negation, the code checks for inequality and makes
no sense.

This is required to run coeffs_compute through SLURM as part of the
EAR learning process.

The P-States / Frequencies that are loaded from the policies are
validated against what the system supports.

This allows using MariaDB in its default configuration, which has a
passwordless root user that cannot login over TCP.

The existing MSR addresses are not supported on Coffee Lake,
and the ones that are supported return garbage.

This is *exactly* what stdout / stderr is there for.

This will only work if CPUs 0-n are enabled and CPUs n-2n are disabled.

The EAR daemon is supposed to parse entries like "NodeUseLog", but
without this change it will ignore any entry that doesn't begin with
"EARD" or "NodeDaemon".
