From: Lukasz Kalamarz <lukasz.kalamarz at intel.com>
As a part of local memory effort we need to make sure, that basic
scenarios are covered for every available memory region. This patch is
an attempt for this problem. If it will be accepted it will be
replicated on each test that can benefit from it.
