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

189 will run faster if you say N here.

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