ARCH_USES_GETTIMEOFFSET but didn't update Sparc correctly, so
that I can apply Stephen Rothwell's fix for that mis-merge.

Linux on the CRIS architecture
==============================
This is a port of Linux 2.4 to Axis Communications ETRAX 100LX embedded
network CPU. For more information about CRIS and ETRAX please see further
below.
This is a port of Linux to Axis Communications ETRAX 100LX,
ETRAX FS and ARTPEC-3 embedded network CPUs.
For more information about CRIS and ETRAX please see further below.
In order to compile this you need a version of gcc with support for the
ETRAX chip family. Please see this link for more information on how to
ETRAX chip family. Please see this link for more information on how to
download the compiler and other tools useful when building and booting

What is CRIS ?
--------------
CRIS is an acronym for 'Code Reduced Instruction Set'. It is the CPU
architecture in Axis Communication AB's range of embedded network CPU's,
called ETRAX. The latest CPU is called ETRAX 100LX, where LX stands for
'Linux' because the chip was designed to be a good host for the Linux
operating system.

The previous version of the ETRAX, the ETRAX 100, sits in almost all of
Axis shipping thin-servers like the Axis 2100 web camera or the ETRAX 100
developer-board. It lacks an MMU so the Linux we run on that is a version
of uClinux (Linux 2.0 without MM-support) ported to the CRIS architecture.
The new Linux 2.4 port has full MM and needs a CPU with an MMU, so it will
not run on the ETRAX 100.
ETRAX 100LX is CRISv10 architecture.
A version of the Axis developer-board with ETRAX 100LX (running Linux
2.4) is now available. For more information please see developer.axis.com.
The ETRAX FS and ARTPEC-3 chips
-------------------------------
The ETRAX FS is a 200MHz 32-bit RISC processor with on-chip 16kB
I-cache and 16kB D-cache and with a wide range of device interfaces
including multiple high speed serial ports and an integrated USB 1.1 PHY.
The ARTPEC-3 is a variant of the ETRAX FS with additional IO-units
used by the Axis Communications network cameras.
See below link for more information:
http://www.axis.com/products/dev_etrax_fs/index.htm
ETRAX FS and ARTPEC-3 are both CRISv32 architectures.

* Samsung Exynos Interrupt Combiner Controller
Samsung's Exynos4 architecture includes a interrupt combiner controller which
can combine interrupt sources as a group and provide a single interrupt request
for the group. The interrupt request from each group are connected to a parent
interrupt controller, such as GIC in case of Exynos4210.
The interrupt combiner controller consists of multiple combiners. Upto eight
interrupt sources can be connected to a combiner. The combiner outputs one
combined interrupt for its eight interrupt sources. The combined interrupt
is usually connected to a parent interrupt controller.
A single node in the device tree is used to describe the interrupt combiner
controller module (which includes multiple combiners). A combiner in the
interrupt controller module shares config/control registers with other
combiners. For example, a 32-bit interrupt enable/disable config register
can accommodate upto 4 interrupt combiners (with each combiner supporting
upto 8 interrupt sources).
Required properties:
- compatible: should be "samsung,exynos4210-combiner".
- interrupt-controller: Identifies the node as an interrupt controller.
- #interrupt-cells: should be <2>. The meaning of the cells are
* First Cell: Combiner Group Number.
* Second Cell: Interrupt number within the group.
- reg: Base address and size of interrupt combiner registers.
- interrupts: The list of interrupts generated by the combiners which are then
connected to a parent interrupt controller. The format of the interrupt
specifier depends in the interrupt parent controller.
Optional properties:
- samsung,combiner-nr: The number of interrupt combiners supported. If this
property is not specified, the default number of combiners is assumed
to be 16.
- interrupt-parent: pHandle of the parent interrupt controller, if not
inherited from the parent node.
Example:
The following is a an example from the Exynos4210 SoC dtsi file.
combiner:interrupt-controller@10440000 {
compatible = "samsung,exynos4210-combiner";
interrupt-controller;

* Freescale MXS GPIO controller
The Freescale MXS GPIO controller is part of MXS PIN controller. The
GPIOs are organized in port/bank. Each port consists of 32 GPIOs.
As the GPIO controller is embedded in the PIN controller and all the
GPIO ports share the same IO space with PIN controller, the GPIO node
will be represented as sub-nodes of MXS pinctrl node.
Required properties for GPIO node:
- compatible : Should be "fsl,<soc>-gpio". The supported SoCs include
imx23 and imx28.
- interrupts : Should be the port interrupt shared by all 32 pins.
- gpio-controller : Marks the device node as a gpio controller.
- #gpio-cells : Should be two. The first cell is the pin number and
the second cell is used to specify optional parameters (currently
unused).
- interrupt-controller: Marks the device node as an interrupt controller.
- #interrupt-cells : Should be 2. The first cell is the GPIO number.
The second cell bits[3:0] is used to specify trigger type and level flags:
1 = low-to-high edge triggered.
2 = high-to-low edge triggered.
4 = active high level-sensitive.
8 = active low level-sensitive.
Note: Each GPIO port should have an alias correctly numbered in "aliases"
node.
Examples:

gpio0 = &gpio0;
gpio1 = &gpio1;
gpio2 = &gpio2;
gpio3 = &gpio3;
gpio4 = &gpio4;

enum dma_data_direction dir);
Direct Userspace Access/mmap Support
------------------------------------
Being able to mmap an export dma-buf buffer object has 2 main use-cases:
- CPU fallback processing in a pipeline and
- supporting existing mmap interfaces in importers.
1. CPU fallback processing in a pipeline
In many processing pipelines it is sometimes required that the cpu can access
the data in a dma-buf (e.g. for thumbnail creation, snapshots, ...). To avoid
the need to handle this specially in userspace frameworks for buffer sharing
it's ideal if the dma_buf fd itself can be used to access the backing storage
from userspace using mmap.
Furthermore Android's ION framework already supports this (and is otherwise
rather similar to dma-buf from a userspace consumer side with using fds as
handles, too). So it's beneficial to support this in a similar fashion on
dma-buf to have a good transition path for existing Android userspace.
No special interfaces, userspace simply calls mmap on the dma-buf fd.
2. Supporting existing mmap interfaces in exporters
Similar to the motivation for kernel cpu access it is again important that
the userspace code of a given importing subsystem can use the same interfaces
with a imported dma-buf buffer object as with a native buffer object. This is
especially important for drm where the userspace part of contemporary OpenGL,
X, and other drivers is huge, and reworking them to use a different way to
mmap a buffer rather invasive.
The assumption in the current dma-buf interfaces is that redirecting the
initial mmap is all that's needed. A survey of some of the existing
subsystems shows that no driver seems to do any nefarious thing like syncing
up with outstanding asynchronous processing on the device or allocating
special resources at fault time. So hopefully this is good enough, since
adding interfaces to intercept pagefaults and allow pte shootdowns would
increase the complexity quite a bit.
Interface:
int dma_buf_mmap(struct dma_buf *, struct vm_area_struct *,
unsigned long);
If the importing subsystem simply provides a special-purpose mmap call to set
up a mapping in userspace, calling do_mmap with dma_buf->file will equally
achieve that for a dma-buf object.
3. Implementation notes for exporters
Because dma-buf buffers have invariant size over their lifetime, the dma-buf
core checks whether a vma is too large and rejects such mappings. The
exporter hence does not need to duplicate this check.
Because existing importing subsystems might presume coherent mappings for
userspace, the exporter needs to set up a coherent mapping. If that's not
possible, it needs to fake coherency by manually shooting down ptes when
leaving the cpu domain and flushing caches at fault time. Note that all the
dma_buf files share the same anon inode, hence the exporter needs to replace
the dma_buf file stored in vma->vm_file with it's own if pte shootdown is
requred. This is because the kernel uses the underlying inode's address_space
for vma tracking (and hence pte tracking at shootdown time with
unmap_mapping_range).
If the above shootdown dance turns out to be too expensive in certain
scenarios, we can extend dma-buf with a more explicit cache tracking scheme
for userspace mappings. But the current assumption is that using mmap is
always a slower path, so some inefficiencies should be acceptable.
Exporters that shoot down mappings (for any reasons) shall not do any
synchronization at fault time with outstanding device operations.
Synchronization is an orthogonal issue to sharing the backing storage of a
buffer and hence should not be handled by dma-buf itself. This is explictly
mentioned here because many people seem to want something like this, but if
different exporters handle this differently, buffer sharing can fail in
interesting ways depending upong the exporter (if userspace starts depending
upon this implicit synchronization).
Miscellaneous notes
-------------------
@ -336,6 +417,20 @@ Miscellaneous notes
the exporting driver to create a dmabuf fd must provide a way to let
userspace control setting of O_CLOEXEC flag passed in to dma_buf_fd().
- If an exporter needs to manually flush caches and hence needs to fake
coherency for mmap support, it needs to be able to zap all the ptes pointing
at the backing storage. Now linux mm needs a struct address_space associated
with the struct file stored in vma->vm_file to do that with the function
unmap_mapping_range. But the dma_buf framework only backs every dma_buf fd
with the anon_file struct file, i.e. all dma_bufs share the same file.
Hence exporters need to setup their own file (and address_space) association
by setting vma->vm_file and adjusting vma->vm_pgoff in the dma_buf mmap
callback. In the specific case of a gem driver the exporter could use the
shmem file already provided by gem (and set vm_pgoff = 0). Exporters can then
zap ptes by unmapping the corresponding range of the struct address_space
associated with their own file.
