Subject: s390x: Make IBM z17 known to Valgrind
X-Git-Tag: VALGRIND_3_26_0~47
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=32fcdbfafd623569df800d2a1fa351c11f10a128;p=thirdparty%2Fvalgrind.git

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.
