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/>.

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

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

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