164	  Enable this if you want to support 64bit kernel on PA-RISC platform.

166	  At the moment, only people willing to use more than 2GB of RAM,
167	  or having a 64bit-only capable PA-RISC machine should say Y here.
168
169	  Since there is no 64bit userland on PA-RISC, there is no point to
170	  enable this option otherwise. The 64bit kernel is significantly bigger

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