I only did some basic testing of the hard-float abi. Bell SW has offered to do

I have no way of knowing if any of the other profiles are being used but I
would think it’s
worth keeping them in the event that someone wants to try to build/test these
other configurations.
The goal of this JEP is to eliminate the arm64 port and not cause any other
changes in behavior.
Sorry I was under the mistaken impression that all of the Oracle ARM
port was being removed, but it is only the 64-bit part.
That said it would concern me greatly if people are still building for
anything older than ARMv7 with MP support! The work I'm doing to always
act as-if MP is not only potentially inefficient on a uniprocessor, but
for ARM variants without MP support, potentially it won't even run if
instructions don't exist. I need to look into this further.
Thanks,
David

Please review the changes related to JEP 340 which remove the second 64-bit ARM

I’ve testing building the remaining 32 and 64 bit ARM ports including the
minimal, client and server VMs.
I’ve run specJVM98 on the three 32-bit ARM VMs.
Did you test all the ARM related abi-profiles? It seems to me they were only
for Oracle's ARM32 port and may have never been used otherwise. I would have
expected all that stuff to be removed.

I also verified that Linux x64 builds.
