Subject: slab allocators: remove multiple alignment specifications
From: Christoph Lameter <clameter@xxxxxxx>
It is not necessary to tell the slab allocators to align to a cacheline
if an explicit alignment was already specified. It is rather confusing
to specify multiple alignments.
Make sure that the call sites only use one form of alignment.
