After seeing a posting from Nemoto-san on the linux-mips list (should
show up soon on,
I'm wondering if these defaults are the culprit;

mm/slab.c:#define ARCH_KMALLOC_MINALIGN __alignof__(unsigned long long)
mm/slob.c:#define ARCH_KMALLOC_MINALIGN __alignof__(unsigned long)
mm/slub.c:#define ARCH_KMALLOC_MINALIGN __alignof__(unsigned long long)

Note that some platforms override this.
