Subject: 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.
