Subject: [PATCH 4.16 62/68] s390/compat: fix setup_frame32
4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heiko Carstens <heiko.carstens@...ibm.com>
commit 8b09ca746a643ca452cd41a522046a96ee5a55fd upstream.
Git commit c60a03fee0e5 ("s390: switch to {get,put}_compat_sigset()")
contains a typo and now copies the wrong pointer to user space.
Use the correct pointer instead.
