They address what Sashiko flagged while reviewing that series (see Link below). This series is based on drm-misc-fixes, which already includes the "Fixes for map() path" series (see Link below). Patch 2 is built on top of 0a8224058a58 from that series. tests/imagination/pvr_vm_map.c, sent separately to igt-dev (see Link below) and not yet merged, tests these paths and passes with this series applied.
