[PATCH] EXPORT_SYMBOL patch for audit_log, audit_log_start, audit_log_end and audit_format

Hi,

This is a trivial patch that enables the possibility of using some auditing
functions within loadable kernel modules (ie. inside a Linux Security Module).

_

Make the audit_log_start, audit_log_end, audit_format and audit_log
interfaces available to Loadable Kernel Modules, thus making possible
the usage of the audit framework inside LSMs, etc.
