Subject[PATCH 4.9 032/148] s390: fix compat system call table
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

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

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

commit e779498df587dd2189b30fe5b9245aefab870eb8 upstream.

When wiring up the socket system calls the compat entries were
incorrectly set. Not all of them point to the corresponding compat
wrapper functions, which clear the upper 33 bits of user space
pointers, like it is required.

Fixes: 977108f89c989 ("s390: wire up separate socketcalls system calls")
