187 you have a system with more than one CPU, say Y.

193 will run faster if you say N here.

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