[ Upstream commit e8b26b2135dedc0284490bfeac06dfc4418d0105 ]
Delete initialization of high order entries in mr cache to decrease initial memory footprint. When required, the administrator can populate the entries with memory keys via the /sys interface.
This approach is very helpful to significantly reduce the per HW function memory footprint in virtualization environments such as SRIOV.
