      Description

        Power10 doesn't support transactional memory instructions. The VM asks the OS on linux which prevents an illegal usage of the feature. However, the VM tries to use these instructions on AIX which are causing SIGILL when UseRTMLocking is enabled. It needs to be disabled for Power10.
