187 a system with only one CPU, like most personal computers, say N. If
188 you have a system with more than one CPU, say Y.

192 you say Y here, the kernel will run on many, but not all,

194 will run faster if you say N here.

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