SL*B: drop kmem cache argument from constructor

From: Alexey Dobriyan
Date: Wed Jul 09 2008 - 21:14:43 EST

Kmem cache passed to constructor is only needed for constructors that are
themselves multiplexeres. Nobody uses this "feature", nor does anybody uses
passed kmem cache in non-trivial way, so pass only pointer to object.

Non-trivial places are:
arch/powerpc/mm/init_64.c
arch/powerpc/mm/hugetlbpage.c

This is flag day, yes.
