- Add two new functions to the AGP driver KPI to bind/unbind arbitrary sets of pages into the GTT. - Avoid possible overflow in agp_generic_alloc_memory. - In agp(4) avoid the need to flush all cpu caches with wbinvd between updating the GTT and flushing the AGP TLB by storing the GTT in write-combining memory. - In agp_amd_bind_page don't flush the AGP TLB. It's done by the calling function. - agp_generic_unbind_memory: flush AGP TLB before unwiring pages agp_bind_pages: assert that pages have been wired down
