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.

The CPU cache must be flushed _before_ we start modifying the kernel map ptes,
...
otherwise data will be missing, which becomes apparent when the kernel evicts
batch buffers which are likely to be written into in the evicted state,
and then rebound to the AGP aperture.
This means we cannot rely on the AGP module to flush the
cache for us.

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.

Make the user_token 44-bit for TTMs, and have them occupy a unique file space
...
starting at 0x00100000000. This will hopefully allow us to use
unmap_mapping_range(). Note that user-space will need
64-bit file offset support.
