  76  * DOC: shared area - role and goal
  77  *
  78  * The shared area contains all the data exported by the upper layer to the
  79  * other layers. Since the bus and transport layer shouldn't dereference
  80  * iwl_priv, all the data needed by the upper layer and the transport / bus
  81  * layer must be here.
  82  * The shared area also holds pointer to all the other layers. This allows a
  83  * layer to call a function from another layer.
  84  *
  85  * NOTE: All the layers hold a pointer to the shared area which must be shrd.
  86  *      A few macros assume that (_m)->shrd points to the shared area no matter
  87  *      what _m is.
  88  *
  89  * gets notifications about enumeration, suspend, resume.
  90  * For the moment, the bus layer is not a linux kernel module as itself, and
  91  * the module_init function of the driver must call the bus specific
  92  * registration functions. These functions are listed at the end of this file.
  93  * For the moment, there is only one implementation of this interface: PCI-e.
  94  * This implementation is iwl-pci.c
