Research direction

Start by reproducing the reported commands, modinfo mt7925_common and logread | grep -iE "mt7", on the affected 6.18.12 build. Trace the mt7925_common module's unresolved hugetlb_optimize_vmemmap_key symbol and verify that mt7925-common and mt7925e load successfully without dependency errors.
