[SCSI] sas: fix removal of devices behind expanders
 
We need to iterate over all children when removing and expander, else
stale objects will be around after host removal.  This fixes the oops
Eric Moore saw when removing and reloading mptsas.

Also don't try the scsi_remove_target call unless operating on an end
device.  The current unconditional call is harmless but confusing.

Numa policy hit/miss statistics

/sys/devices/system/node/node*/numastat

All units are pages. Hugepages have separate counters.

numa_hit			A process wanted to allocate memory from this node,
					and succeeded.
numa_miss			A process wanted to allocate memory from this node,
					but ended up with memory from another.
numa_foreign		A process wanted to allocate on another node,
				    but ended up with memory from this one.
local_node			A process ran on this node and got memory from it.
other_node			A process ran on this node and got memory from another node.
interleave_hit 		Interleaving wanted to allocate from this node
					and succeeded.

For easier reading you can use the numastat utility from the numactl package
(ftp://ftp.suse.com/pub/people/ak/numa/numactl*). Note that it only works
well right now on machines with a small number of CPUs.
