After seeing a posting from Nemoto-san on the linux-mips list (should
show up soon on
http://www.linux-mips.org/archives/linux-mips/2010-05/threads.html),
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.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
