Remove ttm objects.
Make vm aware of PCI memory type buffer objects.
(Only works for pre 2.6.16 kernels for now).

Security fix. Zero pages before they are handed to user space.
...
TTM pages were not cleared when allocated and handed to user space.
Sensitive information may leak.

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.
