-                       This debugging option can be used to override the
-                       default scheduler migration cost matrix. The numbers
-                       are indexed by 'CPU domain distance'.
-                       E.g. migration_cost=1000,2000,3000 on an SMT NUMA
-                       box will set up an intra-core migration cost of
-                       1 msec, an inter-core migration cost of 2 msecs,
-                       and an inter-node migration cost of 3 msecs.

-                       If a system's migration matrix reported at bootup
-                       seems erroneous then this option can be used to
-                       increase verbosity of the detection process.
-                       We default to 0 (no extra messages), 1 will print
-                       some more information, and 2 will be really
-                       verbose (probably only useful if you also have a
-                       serial console attached to the system).

-                       Format=<percent>
-                       This debug option can be used to proportionally
-                       increase or decrease the auto-detected migration
-                       costs for all entries of the migration matrix.
-                       E.g. migration_factor=150 will increase migration
-                       costs by 50%. (and thus the scheduler will be less
-                       eager migrating cache-hot tasks)
-                       migration_factor=80 will decrease migration costs
-                       by 20%. (thus the scheduler will be more eager to
-                       migrate tasks)
