agp: use scratch page on memory remove and at GATT creation V4
Convert most AGP chipset to use scratch page as default entries. This help avoiding GPU querying 0 address and trigger computer fault. With KMS and memory manager we bind/unbind AGP memory constantly and it seems that some GPU are still doing AGP traffic even after GPU report being idle with the memory segment. Tested (radeon GPU KMS + Xorg + compiz + glxgears + quake3) on : - SIS 1039:0001 & 1039:0003 - Intel 865 8086:2571 Compile tested for other bridges V2 enable scratch page on uninorth V3 fix unbound check in uninorth insert memory (Michel Dänzer) V4 rebase on top of drm-next branch with the lastest intel AGP changeset (stable should use version V3 of the patch) Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Michel Dänzer <michel@daenzer.net> Signed-off-by: Dave Airlie <airlied@redhat.com>
