This option enables special console drivers which allow the kernel
to print messages very early in the bootup process.
This is useful for kernel debugging when your machine crashes very
early before the console code is initialized. For normal operation
it is not recommended because it looks on some machines ugly and
oesn't cooperate with an X server. You should normally N here,
unless you want to debug such a crash.

[PATCH] Configurable NODES_SHIFT Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.

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.
People using multiprocessor machines who say Y here should also say
Y to "Enhanced Real Time Clock Support", below.
See also the <file:Documentation/smp.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.

This allows you to specify the maximum number of CPUs which this
kernel will support. The maximum supported value is 32 for 32-bit
kernel and 64 for 64-bit kernels; the minimum value which makes
sense is 1 for Qemu (useful only for kernel debugging purposes)
and 2 for all others.
This is purely to save memory - each supported CPU adds
approximately eight kilobytes to the kernel image. For best
performance should round up your number of processors to the next
power of two.

help
MIPS R10000 does support a 44 bit / 16TB address space as opposed to
previous 64-bit processors which only supported 40 bit / 1TB. If you

This will result in additional memory usage, so it is not

config KEXEC
bool "Kexec system call (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.
config SECCOMP
bool "Enable seccomp to safely compute untrusted bytecode"
depends on PROC_FS && BROKEN
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.

The Extended Industry Standard Architecture (EISA) bus was
developed as an open alternative to the IBM MicroChannel bus.
The EISA bus provided some of the features of the IBM MicroChannel
bus while maintaining backward compatibility with cards made for
the older ISA bus. The EISA bus saw limited use between 1988 and
1995 when it was made obsolete by the PCI bus.
Say Y here if you are building a kernel for an EISA-based machine.
Otherwise, say N.

A 64-bit kernel is usually built using the 64-bit ELF binary object
format as it's one that allows arbitrary 64-bit constructs. For
kernels that are loaded within the KSEG compatibility segments the
32-bit ELF format can optionally be used resulting in a somewhat
smaller binary, but this option is not explicitly supported by the
toolchain and since binutils 2.14 it does not even work at all.
