Implement mm_lock and mm_unlock functions.
...
The mm_lock function is used when leaving vt. It evicts _all_ buffers.
Buffers with the DRM_BO_NO_MOVE attribute set will be guaranteed to
get the same offset when / if they are rebound.

Remove the memory manager parameter from the put_block function, as this
...
makes the client code a lot cleaner. Prepare buffer manager for lock and
unlock calls.

Simplify the AGP backend interface somewhat.
...
Fix buffer bound caching policy changing, Allow
on-the-fly changing of caching policy on bound buffers if the hardware
supports it.
Allow drivers to use driver-specific AGP memory types for TTM AGP pages.
Will make AGP drivers much easier to migrate.

Compatibility code for 2.6.15-2.6.18. It is ugly but a little comfort is that
...
it will go away in the mainstream kernel.
Some bugfixes, mainly in error paths.

Big update:
...
Adapt for new functions in the 2.6.19 kernel.
Remove the ability to have multiple regions in one TTM.
This simplifies a lot of code.
Remove the ability to access TTMs from user space.
We don't need it anymore without ttm regions.
Don't change caching policy for evicted buffers. Instead change it only
when the buffer is accessed by the CPU (on the first page fault).
This tremendously speeds up eviction rates.
Current code is safe for kernels <= 2.6.14.
Should also be OK with 2.6.19 and above.

Fix buffer manager takedown error.
...
Prepare for the possibility to evict all buffers from vram / agp.
This will be used by the X server when, for example, switching vts.
