Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

help
The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
You can operate a Linux system on this board by using an M32R
softmacro core, which is a fully-synthesizable functional model
described in Verilog-HDL.
The Mappi-I board was the first platform, which had been used
to port and develop a Linux system for the M32R processor.
Currently, the Mappi-II, an heir to the Mappi-I, is available.

The M3T-M32700UT is an evaluation board based on uT-Engine
specification. This board has an M32700 (Chaos) evaluation chip.
You can say Y for SMP, because the M32700 is a single chip
multiprocessor.

help
The OAKS32R is a tiny, inexpensive evaluation board.
Please note that if you say Y here and choose chip "M32102",
say N for MMU and select a no-MMU version kernel, otherwise
a kernel with MMU support will not work, because the M32102
is a microcontroller for embedded systems and it has no MMU.

config PREEMPT
bool "Preemptible Kernel"
help
This option reduces the latency of the kernel when reacting to
real-time or interactive events by allowing a low priority process to
be preempted even if it is in kernel mode executing a system call.
This allows applications to run more reliably even when the system is
under load.
Say Y here if you are building a kernel for a desktop, embedded
or real-time system. Say N if you are unsure.
config HAVE_DEC_LOCK
bool
depends on (SMP || PREEMPT)
default n
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.
People using multiprocessor machines who say Y here should also say
Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
Management" code will be disabled if you say Y here.
See also the <file:Documentation/smp.tex>,
<file:Documentation/smp.txt> and the SMP-HOWTO available at
<http://www.linuxdoc.org/docs.html#howto>.
If you don't know what to do here, say N.

range 2 32
depends on SMP
default "2"
help
This allows you to specify the maximum number of CPUs which this
kernel will support. The maximum supported value is 32 and the
minimum value which makes sense is 2.
This is purely to save memory - each supported CPU adds
approximately eight kilobytes to the kernel image.

help
Find out whether you have a PCI motherboard. PCI is the name of a
bus system, i.e. the way the CPU talks to the other stuff inside
your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
VESA. If you have PCI, say Y, otherwise N.
The PCI-HOWTO, available from
<http://www.linuxdoc.org/docs.html#howto>, contains valuable
information about which PCI hardware does work under Linux and which
doesn't.
choice
prompt "PCI access mode"

default PCI_GOANY
config PCI_GOBIOS
bool "BIOS"
---help---
On PCI systems, the BIOS can be used to detect the PCI devices and
determine their configuration. However, some old PCI motherboards
have BIOS bugs and may crash if this is done. Also, some embedded
PCI-based systems don't have any BIOS at all. Linux can also try to
detect the PCI hardware directly without using the BIOS.
With this option, you can specify how Linux should detect the PCI
devices. If you choose "BIOS", the BIOS will be used, if you choose
"Direct", the BIOS won't be used, and if you choose "Any", the
kernel will try the direct access method and falls back to the BIOS
if that doesn't work. If unsure, go with the default, which is
"Any".

help
Enables the display of the minimum amount of free stack which each
task has ever had available in the sysrq-T and sysrq-P debug output.
This option will slow down process creation somewhat.
config DEBUG_PAGEALLOC

help
Unmap pages from the kernel linear mapping after free_pages().
This results in a large slowdown, but helps to find certain types
of memory corruptions.
config FRAME_POINTER

help
If you say Y here the resulting kernel image will be slightly larger
and slower, but it will give very useful debugging information.
If you don't debug the kernel, you can say N, but we may not be able
to solve problems without frame pointers.

* needs to do something only if count was negative before
* the increment operation.

* "sleeping" and the contention routine ordering is protected

* contention on the lock, and as such all this is the

* *info - An arbitrary pointer to pass to the function.

* wait - If true, wait (atomically) until function has
* completed on other CPUs.

* Returns: 0 on success, else a negative status code. Does not return
* until remote CPUs are nearly ready to execute <<func>> or
* are or have executed.
*
* Cautions: You must not call this function with disabled interrupts or
* from a hardware interrupt handler, you may call it from a
