161	  Enable this if you want to support 64bit kernel on PA-RISC platform.
162
163	  At the moment, only people willing to use more than 2GB of RAM,
164	  or having a 64bit-only capable PA-RISC machine should say Y here.
165
166	  Since there is no 64bit userland on PA-RISC, there is no point to
167	  enable this option otherwise. The 64bit kernel is significantly bigger

205	  This enables support for systems with more than one CPU. If you have
206	  a system with only one CPU, like most personal computers, say N. If
207	  you have a system with more than one CPU, say Y.
208
209	  If you say N here, the kernel will run on single and multiprocessor
210	  machines, but will use only one CPU of a multiprocessor machine. If
211	  you say Y here, the kernel will run on many, but not all,
212	  singleprocessor machines. On a singleprocessor machine, the kernel
213	  will run faster if you say N here.
