commit 32fcdbfafd623569df800d2a1fa351c11f10a128
Author: Andreas Arnez <ar...@li...>

s390x: Make IBM z17 known to Valgrind
Make the IBM z17 machine model 9175 known to Valgrind. Also add the
expected output of the s390x-specific "ecag" test case on an IBM z17, so
the test case succeeds on that system.
