1a0d890a42 i915: Add support for scheduled buffer swaps to be done as flips. 
Unfortunately, emitting asynchronous flips during vertical blank results in
tearing. So we have to wait for the previous vertical blank and emit a
synchronous flip.

5a40c043cc Add DRM_VBLANK_FLIP. 
Used to request that a scheduled buffer swap be done as a flip instead of a
blit.

6f89584e13 i915: Improved page flipping support, including triple buffering. 
Pages are tracked independently on each pipe.

Bump the minor version for 3D clients to know page flipping is usable, and
bump driver date.

34aa3393d0 i915: Page flipping enhancements. 
Leave it to the client to wait for the flip to complete when necessary,
but wait for a previous flip to complete before emitting another one. This
should help avoid unnecessary stalling of the ring due to pending flips.

Call i915_do_cleanup_pageflip() unconditionally in preclose.

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.
