 186          you have a system with more than one CPU, say Y.
 187
 188          If you say N here, the kernel will run on single and multiprocessor
 189          machines, but will use only one CPU of a multiprocessor machine. If
 190          you say Y here, the kernel will run on many, but not all,
 191          singleprocessor machines. On a singleprocessor machine, the kernel
 192          will run faster if you say N here.

 214          current process's task_struct whilst in the kernel.
 215
 216          This means the kernel doesn't need to calculate the address each time
 217          "current" is used (take SP, AND with mask and dereference pointer
 218          just to get the address), and instead can just use E2+offset
