    Subject[PATCH] kmalloc() bug in pci-dma.c

    After burning my fingers with a similar mistake in one of the patches
    that I am working on, I did a quick grep to find out all faulty kmalloc()
    calls and found this.

    dma_declare_coherent_memory() is calling kmalloc with wrong arguments.
    Attached patch fixes this.

    Please apply.
