The patch is based on the patch by Andrew Hughes (gnu.andrew at redhat.com),
please see the thread
http://mail.openjdk.java.net/pipermail/hotspot-dev/2015-February/017148.html
The current patch set adds the changes to show the correct architecture in the
'java  -Xinternalversion' output and test_env.sh (both pointed by
goetz.lindenmaier at sap.com), and fixes Serviceability Agent and
 disassembler (hsdis).

I need a sponsor.
