Ok

Not sure how easy that would be. The host_alloc and dp_alloc gets called
at few times _before_ kmem_cache_init() is called, so a kmalloc call
panic()s the kernel.
I know, because I tried to use kmalloc for handling the linked lists for
the dp_alloc/free functions.

It would make allocating buffers in drivers easier.

Cleaning up is always good.

Any more suggestions before I remove the #ifdefs and resubmit?
