 163           Enable this if you want to support 64bit kernel on PA-RISC platform.
 164
 165           At the moment, only people willing to use more than 2GB of RAM,
 166           or having a 64bit-only capable PA-RISC machine should say Y here.
 167
 168           Since there is no 64bit userland on PA-RISC, there is no point to
 169           enable this option otherwise. The 64bit kernel is significantly bigger
 170           and slower than the 32bit one.

 179           This lets you select the page size of the kernel.  For best

 181           compatibility with 32bit applications, a page size of 4KB should be
 182           selected (the vast majority of 32bit binaries work perfectly fine

 187           64KB               For best performance, might give more overhead.

 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.
