The patch should apply cleanly.  Note that overall, the following patches should be picked for s390x since Valgrind 3.16:
* ba73f8d2ebe4b5f  Bug 428648 - s390x: Force 12-bit amode for vector loads
in isel
* 5adeafad7a60b63  Bug 429864 - s390: Use Iop_CasCmp* to fix memcheck false
positives
* 159f132289160ab  Bug 404076 - s390x: Implement z14 vector instructions

Title:
  [21.04 FEAT] Valgrind add new hardware support for z Systems

Status in Ubuntu on IBM z Systems:
  Triaged
Status in valgrind package in Ubuntu:
  New

Bug description:
  Add support of IBM z14 instructions to Valgrind. 
  This is required when running applications built for z14 under Valgrind for debugging purposes.

  The enablement of Valgrind with new instructions is crucial since the
  distro build environments use Valgrind for build validation of e.g.
  Glibc.
