    fat: drop negative dentry on rename() path

    Drop the negative dentry on rename() path, in order to make sure to
    use the case sensitive name which is specified by user if this is for
    creation.

    For it, this uses newly added LOOKUP_RENAME_TARGET like LOOKUP_CREATE.

    fat: make sure to set d_ops in fat_get_parent

    fat_get_parent needs to setup the dentry operations, otherwise we might
    lose them when the NFS server needs to reconnect out of cache inodes.

    irq: for_each_irq_desc() move to irqnr.h

    Impact: cleanup

    before CONFIG_SPARSE_IRQ age, for_each_irq_desc() sat in irqnr.h and
    could be called from generic code.

    CONFIG_SPARSE_IRQ breaks this assumption, but SPARSE_IRQ version
    for_each_irq_desc() also can move into irqnr.h easily.

    Also, this patch unifies CONFIG_SPARSE_IRQ and !CONFIG_SPARSE_IRQ
    for_each_irq_desc().

    Impact: cleanup

    <linux/irq.h> can be removed and should be, because:

      - hrtimer doesn't use any irq feature.
      - <linux/irq.h> shouldn't be include from generic code.

    sparseirq: fix desc->lock init

    Impact: cleanup

    init_one_irq_desc() does not initialize the desc->lock properly -
    you cannot init a lock by memcpying some other lock on it.

    This happens to work right now (because irq_desc_init is never in use),
    but it's a dangerous construct nevertheless, so fix it.
