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.

Please, refer to https://goo.gl/w3dVsq for further details.

The following mm RFC Patch has been proposed to fix this issue:
