+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".
