28	  The PA-RISC microprocessor is designed by Hewlett-Packard and used
29	  in many of their workstations & servers (HP9000 700 and 800 series,
30	  and later HP3000 series).  The PA-RISC Linux project home page is

168	  Enable this if you want to support 64bit kernel on PA-RISC platform.
169
170	  At the moment, only people willing to use more than 2GB of RAM,
171	  or having a 64bit-only capable PA-RISC machine should say Y here.
172
173	  Since there is no 64bit userland on PA-RISC, there is no point to
174	  enable this option otherwise. The 64bit kernel is significantly bigger

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