PATCH 1/1 Better kmalloc effeciency

This patch adds two intermediate general cache sizes, 96 and 192 bytes. On my system this saves about 34k.

size-256              63    180    256    5   12    1
size-192              95    120    192    5    6    1
size-128             213    240    128    8    8    1
size-96             1080   1120     96   28   28    1
