Subject: [PATCH 1/3] Allow flock and ipc syscall for s390 architecture
Date: Tue,  9 May 2017 14:27:13 -0300

In order to use the OpenSSL-ibmpkcs11 engine it is needed to allow flock
and ipc calls, because this engine calls OpenCryptoki (a PKCS#11
implementation) which calls the libraries that will communicate with the
crypto cards. OpenCryptoki makes use of flock and ipc and, as of now,
this is only need on s390 architecture.
