e1460426b8 Bugzilla Bug #9457 
Add refcounting of user waiters to the DRM hardware lock, so that we can use the
DRM_LOCK_CONT flag more conservatively.

Also add a kernel waiter refcount that if nonzero transfers the lock for the kernel context,
when it is released. This is useful when waiting for idle and can be used
for very simple fence object driver implementations for the new memory manager.

It also resolves the AIGLX startup deadlock for the sis and the via drivers.
i810, i830 still require that the hardware lock is really taken so the deadlock remains
for those two. I'm not sure about ffb. Anyone familiar with that code?

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.

4297a83b48 nouveau: get nv30 context switching to work. 
* Pulled in some registers from nv10reg.h.  Needed for context switching.
* Filled in nv30 graphics context (based on nv40_graph.c).
* Figure out nv30 context table, set up on context creation.  Allows the cards automatic switching to work.
