no need to set things to NULL, BSS is zero-cleared by the kernel on
boot. See the code in arch/i386/kernel/head.S (look for surprises)

no need to cast return from kmalloc, it returns (void *) and typecasts are
tiresome to eyes (human eyes, i.e.).

> sd_hardsizes = (int *) kmalloc((sd_template.dev_max << 4) * sizeof(int), GFP_ATOMIC);

same here and elsewhere, I know, it's not yours but while you are there,
please clean up.
