53aee3122a I915 accelerated blit copy functional. 
Fixed - to System memory copies are implemented by
flipping in a cache-coherent TTM,
blitting to it, and then flipping it out.

333c6af47a Protect drm_mmap against disappearing maps. 
The map lists and hash tables are protected using dev->struct_mutex,
but drm_mmap strangely never locked this mutex.

3024f23c65 memory manager: Make device driver aware of different memory types. 
Memory types are either fixed (on-card or pre-bound AGP) or not fixed
(dynamically bound) to an aperture. They also carry information about:

1) Whether they can be mapped cached.
2) Whether they are at all mappable.
3) Whether they need an ioremap to be accessible from kernel space.

In this way VRAM memory and, for example, pre-bound AGP appear
identical to the memory manager.

This also makes support for unmappable VRAM simple to implement.
