11	  The PA-RISC microprocessor is designed by Hewlett-Packard and used
12	  in many of their workstations & servers (HP9000 700 and 800 series,
13	  and later HP3000 series).  The PA-RISC Linux project home page is
14	  at <http://www.parisc-linux.org/>.

65	  This is the processor type of your CPU.  This information is
66	  used for optimizing purposes.  In order to compile a kernel
67	  that can run on all 32-bit PA CPUs (albeit not optimally fast),
68	  you can specify "PA7000" here.
69
70	  Specifying "PA8000" here will allow you to select a 64-bit kernel
71	  which is required on some machines.

118	help
119	  Enable this if you want to support 64bit kernel on PA-RISC platform.
120
121	  At the moment, only people willing to use more than 2GB of RAM,
122	  or having a 64bit-only capable PA-RISC machine should say Y here.
123
124	  Since there is no 64bit userland on PA-RISC, there is no point to
125	  enable this option otherwise. The 64bit kernel is significantly bigger
126	  and slower than the 32bit one.
127
128config SMP
129	bool "Symmetric multi-processing support"
130	---help---
131	  This enables support for systems with more than one CPU. If you have
132	  a system with only one CPU, like most personal computers, say N. If
133	  you have a system with more than one CPU, say Y.
134
135	  If you say N here, the kernel will run on single and multiprocessor
136	  machines, but will use only one CPU of a multiprocessor machine. If
137	  you say Y here, the kernel will run on many, but not all,
138	  singleprocessor machines. On a singleprocessor machine, the kernel
139	  will run faster if you say N here.
140
141	  See also the <file:Documentation/smp.txt>,
142	  <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available
143	  at <http://www.tldp.org/docs.html#howto>.

158	  or have huge holes in the physical address space for other reasons.
