3.12-stable review patch. If anyone has any objections, please let me know.

From: Mathias Krause <minipli@googlemail.com>
commit 64fbff9ae0a0a843365d922e0057fc785f23f0e3 upstream.
We leak 4 bytes of kernel stack in response to an AUDIT_GET request as we miss to initialize the mask member of status_set. Fix that.
