o Updating module parameter after driver load is not supported
except auto_fw_reset parameter. Changing these parameter after
driver load, can have weird result.
o Update driver version to 5.0.15.

Driver is reading flash fw version from defined address, this address
may be invalid. Indeed Driver should read address for fw version through
flash layout table. Flash layout table has defined region and address for
fw version address should be read from fw image region.
Driver has check for old firmware, this bug can cause driver load fail.
This patch will try to read fw version from flash image region, if that fails,
read from defined address.

Dan Rosenberg pointed out that there were some signed comparison bugs
in the phonet protocol.
http://marc.info/?l=full-disclosure&m=129424528425330&w=2
The problem is that we check for array overflows but "protocol" is
signed and we don't check for array underflows. If you have already
have CAP_SYS_ADMIN then you could use the bugs to get root, or someone
could cause an oops by mistake.

The I2C specification explicitly describes both SDA and SCL as
bidirectional lines. An I2C master with a read-only SCL is thus not
compliant. If a slow slave stretches the clock, errors will happen,
so the bus can't be considered as reliable.

Add an i2c mux driver providing access to i2c bus segments using a
hardware MUX sitting on a master bus and controlled through gpio pins.
E.G. something like:
---------- ---------- Bus segment 1 - - - - -
| | SCL/SDA | |-------------- | |
| |------------| |
| | | | Bus segment 2 | |
| Linux | GPIO 1..N | MUX |--------------- Devices
| |------------| | | |
| | | | Bus segment M
| | | |---------------| |
---------- ---------- - - - - -
SCL/SDA of the master I2C bus is multiplexed to bus segment 1..M
according to the settings of the GPIO pins 1..N.

Put the variables accessed together in the hot-path into common
cachelines, and separate them by RW vs RO to avoid false dirtying.
We keep a local copy of the lkey and rkey in the target to avoid
traversing pointers (and associated cache lines) to find them.

We only need the lock to cover list and credit manipulations, so push
those into srp_remove_req() and update the call chains.
We reorder the request removal and command completion in
srp_process_rsp() to avoid the SCSI mid-layer sending another command
before we've released our request and added any credits returned by the
target. This prevents us from returning HOST_BUSY unneccesarily.

We only need locks to protect our lists and number of credits available.
By pre-consuming the credit for the request, we can reduce our lock
coverage to just those areas. If we don't actually send the request,
we'll need to put the credit back into the pool.

We use req->scmnd != NULL to indicate an active request, so there's no
need to keep a separate list for them. We can afford the array iteration
during error handling, and dropping it gives us one less item that needs

pcmcia_request_irq() and pcmcia_enable_device() are intended
to be called from process context (first function allocate memory
with GFP_KERNEL, second take a mutex). We can not take spin lock
and call them.
It's safe to move spin lock after pcmcia_enable_device() as we
still hold off IRQ until dev->base_addr is 0 and driver will
not proceed with interrupts when is not ready.

This is an attempt to fix a long standing open bug:
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1334
The interrupt handler checks for INTA being -1, apparently that means that the
hardware is gone. But the interrupt handler defers actual interrupt processing
to a tasklet. By the time the tasklet is run and checks INTA again, the
hardware might be gone and INTA be -1, which confuses the driver because all
event bits are set.
The patch applies to 2.6.37.

Some Broadcom based wireless devices contain dangling ethernet cores.
This triggers the ssb probing mechanism and tries to load the b44 driver
on this core.
Ignore the dangling core in the ssb core scanning code to avoid
access to the core and failure of b44 probing.

P54_HDR_FLAG_DATA_OUT_SEQNR is meant to tell the
firmware that "the frame's sequence number has
already been set by the application."
Whereas IEEE80211_TX_CTL_ASSIGN_SEQ is set for
frames which lack a valid sequence number and
either the driver or firmware has to assign one.
Yup, it's the exact opposite!

vm_map_ram() is not available on NOMMU platforms, and causes trouble
on incoherrent architectures such as ARM when we access the page data
through both the direct and the virtual mapping.
The alternative is to use the direct mapping to access page data
for the case when we are not crossing a page boundary, but to copy
the data into a linear scratch buffer when we are accessing data
that spans page boundaries.

The SMSC 3320 USB PHY on the OMAP4 Pandaboard needs a 19.2 MHz
reference clock. This clock is provided from the OMAP4's fref_clk3
pad.
Recent changes to clock44xx_data.c made the clock framework aware
of the existence of these fref_clk[i] lines. If the option
CONFIG_OMAP_RESET_CLOCKS is enabled in the kernel, then the
clock framework will turn these clocks off during bootup.
Explicitly request and keep this clock enabled at init for the
Pandaboard, so that the PHY receives this clock at all times.

Using "iptables -L" with a lot of rules have a too big BH latency.
Jesper mentioned ~6 ms and worried of frame drops.
Switch to a per_cpu seqlock scheme, so that taking a snapshot of
counters doesnt need to block BH (for this cpu, but also other cpus).
This adds two increments on seqlock sequence per ipt_do_table() call,
its a reasonable cost for allowing "iptables -L" not block BH
processing.

The addition of 64k block capability in the rec_len_from_disk
and rec_len_to_disk functions added a bit of math overhead which
slows down file create workloads needlessly when the architecture
cannot even support 64k blocks, thanks to page size limits.
Similar changes already exist in the ext4 codebase.
The directory entry checking can also be optimized a bit
by sprinkling in some unlikely() conditions to move the
error handling out of line.
