[PATCH 039/105] MODSIGN: do not send garbage to stderr when enabling modules signature

[Kamal Mostafa]

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

------------------

From: David Cohen <david.a.cohen at intel.com>

commit 07c449bbc6aa514098c4f12c7b04180cec2417c6 upstream.

When compiling kernel with -jN (N > 1), all warning/error messages
printed while openssl is generating key pair may get mixed dots and
other symbols openssl sends to stderr. This patch makes sure openssl
logs go to default stdout.

Example of the garbage on stderr:

crypto/anubis.c:581: warning: ‘inter’ is used uninitialized in this function
Generating a 4096 bit RSA private key
