From d10cd86ee32bf76495f79c02df62fc242adbcbe3 Mon Sep 17 00:00:00 2001
From: Andreas Arnez <arnez@linux.vnet.ibm.com>

Subject: [PATCH] s390x: More fixes for z13 support
This patch addresses the following:
* Fix the implementation of LOCGHI. Previously Valgrind performed 32-bit
sign extension instead of 64-bit sign extension on the immediate value.
* Advertise VXRS in HWCAP. If no VXRS are advertised, but the program
uses vector registers, this could cause problems with a glibc built with
"-march=z13".
