From 200fbe924466720bd2a8c5eb05b05d67b0a2414c Mon Sep 17 00:00:00 2001

Subject: Added support for ENEA OSE

This port has support for both non-smp and smp.

It contains a new way to do io checking in which erts_poll_wait
receives the payload of the polled entity. This has implications
for all linked-in drivers.
