Once the hotplugging (6b42f7563) patchset were merged, DPAA2 Physical Addressing mode and DPAA observed drastic performance drop (~95%) This was because of an inherent assumption while doing some memory translation that memsegs would be physically contiguous
This series attempts to add a workaround for that - a intermediary one while complete solution is integrated This work around creates a linked list of referenced buffers and attempts to search through it during physical to virtual translations.
