 Most existing servers do not implement RPCSEC_GSS for either the lockd or
 statd daemons.

 This makes for an interesting situation in which programs compiled
 to use flock() and running on the server will not see the locks that
 are set by the clients. The clients will, however, see both POSIX and
 flock() locks set by other clients.

 It is the best you can do, given the limitations of the protocol.

 AUTH_UNIX credentials really only depend on the process uid/gid/groups
 information. In particular there is no dependency on any strict rpc_client
 specific information. Might as well share them all between all RPC clients.

  Some RPC authentication flavours are not related to the uid (AUTH_NULL

 RPC call async is supposed to return an error if and only if

 Currently, if we restart an RPC call after having set an RPC delay (for
 instance in the case where an NFS EJUKEBOX error has occurred) the call
 to rpc_delete_timer() at the top of the rpc_execute() loop will
 kill off our timer.

 This patch causes rpc_delete_timer() to detect if the rpc_task is still
 queued on a wait queue, and refuse to delete the timer if this is the case.

The EISA EEPROM driver was being initialised too early, before miscdevs
can be registered.  But EISA needs to be registered early -- before PCI.
So stash the EEPROM address in a global variable at EISA init time,
then pick it up later in the EISA EEPROM driver.

Also ioremap() it, use readb instead of gsc_readb and rename the
miscdev to not have a space in the name.
