Christoph Lameter 47bfdc0d5a SLUB: change default alignments
Structures may contain u64 items on 32 bit platforms that are only able to
address 64 bit items on 64 bit boundaries.  Change the mininum alignment of
slabs to conform to those expectations.

ARCH_KMALLOC_MINALIGN must be changed for good since a variety of structure
are mixed in the general slabs.

ARCH_SLAB_MINALIGN is changed because currently there is no consistent
specification of object alignment.  We may have that in the future when the
KMEM_CACHE and related macros are used to generate slabs.  These pass the
alignment of the structure generated by the compiler to the slab.

With KMEM_CACHE etc we could align structures that do not contain 64
bit values to 32 bit boundaries potentially saving some memory.
