Staging: merge staging patches into Linus's main branch

There were a number of patches that went into Linus's
tree already that conflicted with other changes in the
staging branch.  This merge resolves those merge conflicts.

DONE:
- functionality similar to logic testbench
TODO:
- checkpatch.pl cleanups.
- keep state of DMA engines.
- keep data structure that keeps state of each transfer.
- interrupt handler should iterate over outstanding descriptor tables.
- complete userspace cdev to read/write using the DMA engines.
- split off the DMA support functions in a module, re-usable by custom
drivers.

This is batman-advanced implemented as Linux kernel driver. It does not depend
on any network (other) driver, and can be used on wifi as well as ethernet,
vpn, etc ... (anything with ethernet-style layer 2).
It compiles against and should work with Linux 2.6.20 - 2.6.31. Supporting older
versions is not planned, but it's probably easy to backport it. If you work on a
backport, feel free to contact us. :-)

This output format is a graphviz formatted text file which can be

The labels are similar/compatible to the ETX metric, 1.0 means perfect
connection (100%), 2.0 means 50%, 3.0 means 33% and so on.
Alternatively, a JSON output format is available. The format can be set
using by writing either "dot_draw" or "json" into the vis_format file.
"dot_draw" is selected by default.
echo "json" > /proc/net/batman-adv/vis_format
The output is in a generic raw format. Use the batctl tool (See below)
to convert this to other formats more suitable for graphing, eg
graphviz dot, or JSON data-interchange format.

LOGGING/DEBUGGING
-----------------
All error messages, warnings and information messages are sent to the
kernel log. Depending on your operating system distribution this can be
read in one of a number of ways. Try using the commands: dmesg,
logread, or looking in the files /var/log/kern.log or
/var/log/syslog. All batman-adv messages are prefixed with
"batman-adv:" So to see just these messages try
dmesg | grep batman-adv
When investigating problems with your mesh network it is sometimes
necessary to see more detail debug messages. This must be enabled when
compiling the batman-adv module. Use "make menuconfig" and enable the
option "B.A.T.M.A.N. debugging".
The additional debug output is by default disabled. It can be enabled
either at kernel module load time or during run time. To enable debug
output at module load time, add the module parameter debug=<value>.
<value> can take one of four values.
0 - All debug output disabled
1 - Enable messages related to routing / flooding / broadcasting
2 - Enable route or hna added / changed / deleted
3 - Enable all messages
e.g.
modprobe batman-adv debug=2
will load the module and enable debug messages for when routes or HNAs
change.
The debug output can also be changed at runtime using the file
/sys/module/batman-adv/parameters/debug. e.g.
echo 2 > /sys/module/batman-adv/parameters/debug
enables debug messages for when routes or HNAs
The debug output is sent to the kernel logs. So try dmesg, logread etc
to see the debug messages.

cols above layer 2. Therefore the common diagnosis tools do not work as
expected. To overcome these problems batctl was created. At the moment
the batctl contains ping, traceroute, tcpdump and interfaces to the
