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

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

help
Enable this if you want to support 64bit kernel on PA-RISC platform.
At the moment, only people willing to use more than 2GB of RAM,
or having a 64bit-only capable PA-RISC machine should say Y here.
Since there is no 64bit userland on PA-RISC, there is no point to
enable this option otherwise. The 64bit kernel is significantly bigger
and slower than the 32bit one.
config SMP
bool "Symmetric multi-processing support"
---help---
This enables support for systems with more than one CPU. If you have
a system with only one CPU, like most personal computers, say N. If
you have a system with more than one CPU, say Y.
If you say N here, the kernel will run on single and multiprocessor
machines, but will use only one CPU of a multiprocessor machine. If
you say Y here, the kernel will run on many, but not all,
singleprocessor machines. On a singleprocessor machine, the kernel
will run faster if you say N here.
See also the <file:Documentation/smp.txt>,
<file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available
at <http://www.tldp.org/docs.html#howto>.
If you don't know what to do here, say N.

Say Y to support efficient handling of discontiguous physical memory,
for architectures which are either NUMA (Non-Uniform Memory Access)
or have huge holes in the physical address space for other reasons.
