In linux kernel since version 3.10 (release Date: 2013-06-30)  
Select this if you wish to run an SMP kernel across multiple cores
within a MIPS Coherent Processing System. When this option is
enabled the kernel will probe for other cores and boot them with
no external assistance. It is safe to enable this when hardware
support is unavailable.
