mcountseg(), mfreeseg(): use Pte.first/last pointers when possible and avoid constructs like s->map[i]->pages[j]. freepte(): do not zero entries in freepte(), the segment is going away and here is no point in zeroing page pointers. hoist common code at the top avoiding duplication. segpage(), fixfault(): avoid load after store for Pte** pointer. fixfault(): return -1 in default case to avoid the "used but not set" warning for mmuphys and get rid of the useless initialization. syssegflush(): due to len being unsigned, the pe = PGROUND(pe) can make "chunk" bigger than len causing a overflow. rewrite the function and deal with page alignment and errors at the beginning. syssegflush(), segpage(), fixfault(), putseg(), relocateseg(), mcountseg(), mfreeseg(): keep naming consistent. |
