linux/arch/ppc64/Kconfig
Sam Ravnborg d5950b4355 [NET]: add a top-level Networking menu to *config 
Create a new top-level menu named "Networking" thus moving
net related options and protocol selection way from the drivers
menu and up on the top-level where they belong.

To implement this all architectures has to source "net/Kconfig" before
drivers/*/Kconfig in their Kconfig file. This change has been
implemented for all architectures.

Device drivers for ordinary NIC's are still to be found
in the Device Drivers section, but Bluetooth, IrDA and ax25
are located with their corresponding menu entries under the new
networking menu item.

Enabling this option will make the kernel run more efficiently
on logically-partitioned pSeries systems which use shared
processors, that is, which share physical processors between
two or more partitions.
config KEXEC
bool "kexec system call (EXPERIMENTAL)"
depends on PPC_MULTIPLATFORM && EXPERIMENTAL
help
kexec is a system call that implements the ability to shutdown your
current kernel, and to start another kernel. It is like a reboot
but it is indepedent of the system firmware. And like a reboot
you can start any kernel with it, not just Linux.
The name comes from the similiarity to the exec system call.
It is an ongoing process to be certain the hardware in a machine
is properly shutdown, so do not be surprised if this code does not
initially work for you. It may help to enable device hotplugging
support. As of this writing the exact hardware interface is
strongly in flux, so no good recommendation can be made.

Cause the compiler to optimize for POWER4 processors. The resulting
binary will not work on POWER3 or RS64 processors when compiled with
binutils 2.15 or later.
config IOMMU_VMERGE
bool "Enable IOMMU virtual merging (EXPERIMENTAL)"
depends on EXPERIMENTAL
default n
help
Cause IO segments sent to a device for DMA to be merged virtually
by the IOMMU when they happen to have been allocated contiguously.
This doesn't add pressure to the IOMMU allocator. However, some
drivers don't support getting large merged segments coming back
from *_map_sg(). Say Y if you know the drivers you are using are
properly handling this case.
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, 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 single-processor machines.
On a single-processor machine, the kernel will run faster if you say
N here.
If you don't know what to do here, say Y.

config SECCOMP
bool "Enable seccomp to safely compute untrusted bytecode"
depends on PROC_FS
default y
help
This kernel feature is useful for number crunching applications
that may need to compute untrusted bytecode during their
execution. By using pipes or other transports made available to
the process as file descriptors supporting the read/write
syscalls, it's possible to isolate those applications in
their own address space using seccomp. Once seccomp is
enabled via /proc/<pid>/seccomp, it cannot be disabled
and the task is only allowed to execute a few safe syscalls
defined by each seccomp mode.
If unsure, say Y. Only embedded should say N here.
