Openjdk8 still has failing tests on ppc64el

[Breno Leitão]

Looking at the openjdk8 buidlog for ppc64el arch on 16.04[1], there are a lot of failures and we want to start having these problems solved. These tests are also failing on upstream release.

These are the tests that are failing at the moment:

Since we still don't have access to open a bug on the openjdk project, we are tracking it on Ubuntu for a while, but the plan is to have all the fixes sent to OpenJDK upstream project.

[Gustavo Romero (gromero)]

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: https://goo.gl/QWa6Ap

[Gustavo Romero (gromero)]

Currently - tag jdk9-b88, upstream: jdk9/jdk9 repo - many Hotspot tests under compiler/rtm are failing. The immediate problem is that RTM, although already implemented is not enabled for Linux in pppc64le.

To enable the following patch is proposed: http://goo.gl/5GHaQu

All tests under compiler/rtm/cli will pass plus a few others (total of 11 more passing): http://goo.gl/CiEMtX

both patches in comments #1 and #2 don't apply, other patches need back porting.
