staging: make PCI device id constant

The id_table field of the struct pci_driver is constant in <linux/pci.h>
so it is worth to make the initialization data also constant.

The semantic match that finds this kind of pattern is as follows:

Staging: otus: Fix ZM_SEQ_DEBUG macro for no-debug case

tcp_seq is only initialised in case where ZM_ENABLE_PERFORMANCE_EVALUATION
is defined. So move the call to ZM_SEQ_DEBUG() and the decleration of
tcp_seq in there too.  This allows ZM_SEQ_DEBUG() to be removed from the
non-ZM_ENABLE_PERFORMANCE_EVALUATION case in the header file.

This resolves several compile warnings for the
non-ZM_ENABLE_PERFORMANCE_EVALUATION case.
However, the ZM_ENABLE_PERFORMANCE_EVALUATION
case seems to be completely broken.

Staging: rtl8192su: buffer overflow in r8192U_core.c

There was a buffer overflow in the original code.  rf_path was 2 and it should
have been only 0 or 1.

I don't have the hardware for this, so I can't test it.

Looking at the code, there are two almost identical sections for updating the
hal variables.  The first one was clearly wrong and had the array overflow as
well.  The second one looked correct.  I decided to use the second section as
is except for whitespace changes.

The differences between the two original sections:
1)  The second one had more debug output.
2)  The second one looped over rf_path instead of corrupting data.
3)  The second one had these additional assigments.
                      if (rf_path == 0) {
                              priv->TxPowerLevelOFDM24G[i] = priv->RfTxPwrLevelOfdm1T[rf_path][i] ;
                              priv->TxPowerLevelCCK[i] = priv->RfTxPwrLevelCck[rf_path][i];

printk() since kernel version 2.6.29 has supported printing MAC
addresses directly, as an extension to the %p processing. This patch
makes use of this for printk() and bat_dbg(). This will remove the

Staging: batman-adv: Allow the MAC address to be set

Some embedded devices have very limited sources of entropy for the

address on the interface bat0 is not always random. When testing with

Staging: batman-adv: receive packets directly using skbs

This patch removes the (ugly and racy) packet receiving thread and the
kernel socket usage. Instead, packets are received directly by registering
the ethernet type and handling skbs instead of self-allocated buffers.

Some consequences and comments:

 * we don't copy the payload data when forwarding/sending/receiving data
   anymore. This should boost performance.
 * packets from/to different interfaces can be (theoretically) processed
   simultaneously. Only the big originator hash lock might be in the way.
 * no more polling or sleeping/wakeup/scheduling issues when receiving
   packets
 * this might introduce new race conditions.
 * aggregation and vis code still use packet buffers and are not (yet)
   converted.
 * all spinlocks were converted to irqsave/restore versions to solve
   some lifelock issues when preempted. This might be overkill, some
   of these locks might be reverted later.
 * skb copies are only done if neccesary to avoid overhead

performance differences:

 * we made some "benchmarks" with intel laptops.
 * bandwidth on Gigabit Ethernet increased from ~500 MBit/s to ~920 MBit/s
 * ping latency decresed from ~2ms to ~0.2 ms

I did some tests on my 9 node qemu environment and could confirm that
usual sending/receiving, forwarding, vis, batctl ping etc works.

Staging: batman-adv: Use forw_bcast_list_lock always with disabled interrupts

forw_bcast_list_lock is spin_locked in both process and softirq context.
SoftIRQ calls the spinlock with disabled IRQ and normal process context
with enabled IRQs.

When process context is inside an spin_locked area protected by
forw_bcast_list_lock and gets interrupted by an IRQ, it could happen
that something tries to lock forw_bcast_list_lock again in SoftIRQ
context. It cannot proceed further since the lock is already taken
somewhere else, but no reschedule will happen inside the SoftIRQ
context. This leads to an complete kernel hang without any chance of
resurrection.

All functions called in process context must disable IRQs when they try
to get get that lock to to prevent any reschedule due to IRQs.

staging: add Broadcom Crystal HD driver

This patch supersedes the earlier ones sent by Manu Abraham to add
the Broadcom Crystal HD driver to the staging tree, per discussion
with him about it. I've been working with Broadcom's Naren Sankar
on this driver for a number of months, and had already talked Naren
about submitting this on Broadcom's behalf, didn't expect anyone
else to jump on submitting it as quickly as Manu did. ;)

This version is a one-shot deal, incorporating the original driver,
Manu's coding style clean-ups, udev device creation support from
Edgar 'gimli' Hucek, and a number of other small tweaks from myself
and Scott Davilla, the other individual who has been working closely
on this code with Naren and I.

I've tested this iteration of the code lightly on a mini pci-e board
in a ThinkPad T61p running x86_64 Fedora 12, with the expected results,
and will test further on other systems with other variants of the card
(I have three varieties of this device currently in hand). Scott has
also tested on assorted primarily i686 varieties of Ubuntu, and Naren
has tested with both Fedora and Ubuntu, iirc.

Note: only the 70012 is currently supported by this driver, 70015
support will follow later. Also note that Blu-Ray support isn't
enabled (at the firmware level), due to misc fun related to the
BD encryption scheme, DRM, etc. :\

I *do* have a git tree containing the driver, lib, gst plugin and
firmware that I'm working from at the moment[*], as there are inter-
dependencies between the driver and lib, and the driver can be used
with kernels going a ways back (I've only tested back to 2.6.18 as
it exists in Red Hat Enterprise Linux 5). I'm exporting from there,
into a linux-next tree, then generating patches from there. The goal
is to feed everything upstream as quickly as possible, but there are
users who want this code for earlier kernels too...

The firmware will be submitted for inclusion in dwmw2's linux-firmware
tree once there is a suitable redistribution-no-modification type of
license on it (I believe Naren is working with Broadcom legal to get
that in place).

Staging: s5k3e2fx.c: simplify complexity by factoring

the code was looping, setting s_move[i] to the following calculations

if (actual_step>= 0)
         s_move[i] = ((((i + 1) * gain + 0x200) - (i * gain + 0x200)) / 0x400);
else
         s_move[i] = ((((i + 1) * gain - 0x200) - (i * gain - 0x200)) / 0x400);

but, this code reduces to the expression
s_move[i] = gain>>  10;

The reason for the complexity was to generate a step function with
integer division and rounding to land on specific values. But these calculations
can be simplified to the following code:

gain = ((actual_step<<  10) / 5)>>  10;
for (i = 0; i<= 4; i++)
s_move[i] = gain;

Staging: udlfb: add dynamic modeset support

Add dynamic modeset support

udlfb uses EDID to find the monitor’s preferred mode
udlfb no longer has fixed mode tables – it’s able to set any mode
dynamically, from the standard VESA timing characteristics of the monitor.

Draws from probe and setmode code of both displaylink-mod 0.3 branch of
Roberto De Ioris, and Jaya Kumar's displaylinkfb.
Lays foundation for defio support and making backbuffer optional.
With additional changes to minimize diffs and clean for checkpatch.pl style.

Does not yet include new ioctls or refcount/mutex code from displaylink-mod.

Tested to work with existing xf-video-displaylink X server unmodified.
