In linux kernel since version 3.10 (release Date: 2013-06-30)  
This option is selected by any driver which registers a
device or driver on the VOP Bus, such as CONFIG_INTEL_MIC_HOST
and CONFIG_INTEL_MIC_CARD.

If you are building a host/card kernel with an Intel MIC device
then say M (recommended) or Y, else say N. If unsure say N.

More information about the Intel MIC family as well as the Linux
OS and tools for MIC to use with this driver are available from
