The following tests are passing in x86 32 bits (Linux):

 * jdk/test/com/sun/crypto/provider/Cipher/AES/TestGHASH.java

The following tests are failing in x86 32 bits (Linux):

 * hotspot/test/compiler/7184394/TestAESMain.java

The reason why TestAESMain fails is that there is a known bug fixed by
8130341 [1]. I've applied my 8u backport of 8130341 [1] and can confirm
that the test passes. So I suggest not to block the 8u backport of
8073108 and proceed with a 8u backport of 8130341 thereafter.

Note: a 8u backport of 8130341 has been proposed by Yuri Gaevsky here:
http://mail.openjdk.java.net/pipermail/jdk8u-dev/2019-October/010437.html This
backport is identical to mine (except for the commit headers which were
not included in Yuri's patch).

Thanks,
Martin.-
