other branch as normal asm-generic changes do. One is a fix for a
build warning, the other two are more interesting:
* A patch from Mark Brown to allow using the common clock infrastructure
on all architectures, so we can use the clock API in architecture
independent device drivers.
* The UAPI split patches from David Howells for the asm-generic files.
There are other architecture specific series that are going through
the arch maintainer tree and that depend on this one.
There may be a few small merge conflicts between Mark's patch and
the following arch header file split patches. In each case the solution
will be to keep the new "generic-y += clkdev.h" line, even if it
ends up being the only line in the Kbuild file.

OpenRISC Linux
==============
This is a port of Linux to the OpenRISC class of microprocessors; the initial
target architecture, specifically, is the 32-bit OpenRISC 1000 family (or1k).
For information about OpenRISC processors and ongoing development:
website http://openrisc.net
For more information about Linux on OpenRISC, please contact South Pole AB.
email: info@southpole.se

---------------------------------------------------------------------
Build instructions for OpenRISC toolchain and Linux
===================================================
In order to build and run Linux for OpenRISC, you'll need at least a basic
toolchain and, perhaps, the architectural simulator. Steps to get these bits
in place are outlined here.
1) The toolchain can be obtained from openrisc.net. Instructions for building
a toolchain can be found at:
http://openrisc.net/toolchain-build.html
2) or1ksim (optional)
or1ksim is the architectural simulator which will allow you to actually run
your OpenRISC Linux kernel if you don't have an OpenRISC processor at hand.
git clone git://openrisc.net/jonas/or1ksim-svn
cd or1ksim
./configure --prefix=$OPENRISC_PREFIX
make
make install
3) Linux kernel
Build the kernel as usual
make ARCH=openrisc defconfig
make ARCH=openrisc
4) Run in architectural simulator
Grab the or1ksim platform configuration file (from the or1ksim source) and
together with your freshly built vmlinux, run your kernel with the following
incantation:
sim -f arch/openrisc/or1ksim.cfg vmlinux
---------------------------------------------------------------------
Terminology
===========
In the code, the following particles are used on symbols to limit the scope
to more or less specific processor implementations:
openrisc: the OpenRISC class of processors
or1k: the OpenRISC 1000 family of processors
or1200: the OpenRISC 1200 processor
---------------------------------------------------------------------
