Severity   : normal
Bugzilla   : 12459
Description: Client eviction due to failover config
Details    : after a connection loss, the lustre client should attempt to
	     reconnect to the last active server first before trying the
	     other potential connections.

b=6411 : enable rate-limiting of console error messages, and some console
         errors now go only to the kernel log.  Use CERROR/CWARN where
	 appropriate to allow rate-limiting of these messages.
b=1693 : add /proc/sys/portals/catastrophe entry which will report if
         that node has previously LBUGged.

The compatibility macro for cpu_online() had reversed parameters.

	  - removed CFS_DECL_MUTEX*
	    just use 'struct semaphore' and initialise with init_mutex()

	  - removed CFS_DECL_RWSEM*
	    just use 'struct rw_semaphore' and initialise with init_rwsem()

	  - renamed cfs_sleep_chan -> cfs_waitq
	            cfs_sleep_link -> cfs_waitlink

          - fixed race in linux version of arch-independent socknal
  	    (the ENOMEM/EAGAIN decision).

	  - Didn't fix problems in Darwin version of arch-independent socknal
 	    (resetting socket callbacks, eager ack hack, ENOMEM/EAGAIN decision)

	  - removed libcfs types from non-socknal header files (only some types
	    in the header files had been changed; the .c files hadn't been
	    updated at all).

	  - Updated lustre b1_4 to match
