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