This patch increases the range of slab sizes available to kmalloc, adding
slabs half way between the existing power of two sized ones, so allowing
slightly
more efficient use of memory.
Most of the new slabs already exist as kmem_cache slabs so only the 1.5k,3k
6k
are entirely new.
The code
Use the always inlined function kmalloc_index to translate
sizes to indexes, so that we don't have to have the slab indexes
hard coded in two places.

This patch add new slabs sized at 1.5 * 2^n.
i.e - 24,48,96,192,384,768,1.5k,3k,6k
Most of which already exist as kmem_cache slabs, except for 1.5k, 3k 6k.
There is no extra overhead for statically sized kmalloc, and only a small
change for dynamically sized ones.
Minimal code changes:
