11debaf6e4 added CACHE_UNLOCKED_PAGES flag to allow caches' pages to be created with no locking instead of full locking.

6bad493439 pushed the slab init a bit deeper. added a object cache based allocator, including a bootstrap mechanism to have it init during bootup.

6e31ae98f9 some object cache / slab improvements. 
- call the reclaimer callback when low on memory.
 - use the depot when on multi-cpu setups (for scalability).
 - fixed the amount of memory spent on slabs for very large objects.

11b5020f2f rewrote the object cache (slab) implementation a bit, preparing for further integration.

5d6551d69f removed some of the slab's initial heavy debugging. we now merge the links into the slab itself resulting in zero overhead per buffer with MergedLink strategy.

e6fb3d3947 more slab fixes, also introduced a new strategy optimized for medium sized buffers (64 >= x < 512) with lengths other than power of 2 (has an overhead of 2 words per buffer).

dd89ad0e7e added locking to slab's Cache<>. Now we react to system's low memory conditions freeing up empty slabs.

81423c91c7 added initial slab code to the kernel. It is still unused, and there is still no VM interaction.
