[PATCH] msi: Only keep one msi_desc in each slab entry.
It looks like someone confused kmem_cache_create with a different allocator and was attempting to give it knowledge of how many cache entries there were. With the unfortunate result that each slab entry was big enough to hold every irq. Signed-off-by: Eric W.
