Subject: [ 33/37] s390/compat: fix compat wrappers for process_vm system calls

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

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

From: Heiko Carstens <heiko.carstens@...ibm.com>

commit 82aabdb6f1eb61e0034ec23901480f5dd23db7c4 upstream.

The compat wrappers incorrectly called the non compat versions of
the system process_vm system calls.
