Currently - tag jdk9-b88, upstream: jdk9/jdk9 repo - Hotspot test runtime/StackGuardPages is failing due to a different behavior on ppc64le kernel mm in comparison with other architectures. When the stack reaches the limit determined by ulimit it generates a SIG_SEGV, but with si->si_code = SEGV_ACCERR, whilst other architectures return for same event a si->si_code = SEGV_MAPERR.
