Slab cache

[Hartmut Birr]

Hi,

do we need the slab cache in ntoskrnl\mm\slab.c? I've replaced the kmap 
functions (ntoskrnl\mm\kmap.c) by a process local mapping (hyperspace). 
The slab cache needs the mapping for a longer time and cannot use the 
hyperspace mapping. I  would remove the slab cache, because it is not 
used by any of the kernel functions.

My vote is to remove it.

Remove it, IIRC it's something that we don't use anymore.
