[PATCH] s390: fix slab debugging
With CONFIG_SLAB_DEBUG=y networking over qeth doesn't work. The problem is
that the qib structure embedded in the qeth_irq structure needs an alignment
of 256 but kmalloc only guarantees an alignment of 8. When using SLAB
debugging the alignment of qeth_irq is not sufficient for the embedded qib
structure which causes all users of qdio (qeth and zfcp) to stop working.
Allocate qeth_irq structure with __get_free_page. That wastes a small amount
of memory (~2500 bytes) per online adapter.
