Problem Details: a00b10c360b35d6431a "Only enforce fence limits inside the GTT" also added a fenceable/mappable disdinction when binding/pinning buffers. This only complicates the code with no pratical gain: - In execbuffer this matters on for g33/pineview, as this is the only chip that needs fences and has an unmap...

Problem Details: In a00b10c360b35d6431a "Only enforce fence limits inside the GTT" Chris Wilson implemented an optimization to only pin framebuffers as mappable for crtc_set_base (but not for pageflips). This breaks the abi, eg: A double buffering mesa client might leave the last framebuffer in unmappable space on clos...

Problem Details: On certain VIA chipsets AES-CBC requires the input/output to be a multiple of 64 bytes. We had a workaround for this but it was buggy as it sent the whole input for processing when it is meant to only send the initial number of blocks which makes the rest a multiple of 64 bytes.
