Subject: [ 01/32] s390/compat: fix compat wrappers for process_vm system calls

From: Greg KH <gregkh@...uxfoundation.org>

3.4-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.
