The new noexec test fails on s390x with "unexpected SEGV". This test overwrites code using libc's memcpy(), which uses VSTL instruction. host_signal_write() does not recognize it, which causes SEGV to be incorrectly forwarded to the test.Add all vector instructions that write to memory to host_signal_write().
