A couple of one liners to resolve two issues that have come up regarding
audit.

Roger reported a problem with audit.c:audit_receive_skb which improperly
negates the errno argument when netlink_ack is called.

The second issue was reported by Steve on the linux-audit list,
auditsc.s:audit_log_exit using %u instead of %d in the audit_log_format
call.

Please note, there is a mailing list available for audit discussion at
