Subject: [RFC PATCH v7 06/16] uapi|audit: add trust audit message definitions

From: Deven Bowers <deven.desai@...ux.microsoft.com>

Introduce new definitions to audit.h centered around trust
decisions and policy loading and activation, as an extension
of the mandatory access control fields.

Signed-off-by: Deven Bowers <deven.desai@...ux.microsoft.com>

Relevant changes since v6:
  * Change audit records to MAC region (14XX) from
    Integrity region (18XX), as IPE is an effectively a MAC system
    around trust versus an extension to the integrity subsystem.
  * Generalize the #defines to support the class of trust-based
    Access-Control LSMs.
