Modified files:
sys/i386/i386 pmap.c
Log:
Fix a hideous TLB bug. pmap_unmapdev neglected to remove the device
mappings from the page tables, which were mapped with PG_G! We could
reuse the page table entry for another mapping (pmap_mapdev) but it
would never have cleared any remaining PG_G TLB entries.
