 		Briefly, the files above are:
 
-		core_id: the CPU core ID of cpuX. Typically it is the
-		hardware platform's identifier (rather than the kernel's).
-		The actual value is architecture and platform dependent.
-
 		core_siblings: internal kernel map of cpuX's hardware threads
 		within the same physical_package_id.
