Please backport Linux kernel upstream commit ID:
commit 342300cc9cd3428bc6bfe5809bfcc1b9a0f06702
Author: Martin Schwidefsky <schwidefsky@de.ibm.com>
Date: Fri Feb 19 14:44:14 2016 +0100
s390/compat: correct restore of high gprs on signal return
git commit 8070361799ae1e3f4ef347bd10f0a508ac10acfb
"s390: add support for vector extension"
broke 31-bit compat processes in regard to signal handling.
The restore_sigregs_ext32() function is used to restore the additional
elements from the user space signal frame. Among the additional elements
are the upper registers halves for 64-bit register support for 31-bit
processes. The copy_from_user that is used to retrieve the high-gprs
array from the user stack uses an incorrect length, 8 bytes instead of
64 bytes. This causes incorrect upper register halves to get loaded.
