I updated the radio-si470x driver another time. Here are the commented history entries:
- number of seek_retries changed to tune_timeout
The last versions checked for the end of frequency tuning by polling a si470x register.
Therefore polling depended on the usb utilization.
This was changed to have a constant timeout now.
- fixed problem with incomplete tune operations by own buffers
The last version used a shared buffer to assembly the USB HID reports.
It sometimes happened, that multiple functions were modifing this buffer simultanuously.
When sending such reports, the hardware returned USB stalls (-EPIPE).
Now buffers of the correct size (smaller than before) are allocated as local variables.
- optimization of variables
The size of some variables has been reduced to allow the compiler to generate more optimized code.
- improved error logging
At some important location, error checking was improved.
Especially the usb transfers to access si470x registers and the tuning functions were modified.

As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes.
This patch moves the functions that videodev needs from v4l2-common. It also
fixes some Kconfig changes.
After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked
into kernel. v4l2-common will be m, and all V4L drivers will also be m.
This approach is very conservative, since it is possible to have V4L drivers
that don't need I2C or v4l2-common. The better is to map what drivers really
need v4l2-common, making them to select v4l2-common, and allowing the others to
be 'y', 'm' and 'n'.

This adds printk messages with basic information about the driver being loaded.
This information includes a summary of the compiled-in features, which
simplifies bug-reporting and debugging a lot.
Also a firmware ID is printed. This is a unique identifier blob for a specific
version of the firmware. This ID is attached to a specific version of the firmware
blob in b43-fwcutter (see fwcutter git).
This helps users to select the right firmware for their device.
This also makes it possible to use automated scripts to fetch and extract the right
firmware for the driver. (The script will grep the .ko for the "Firmware-ID: xxx" string.)
While the driver might still support other versions of the firmware for backward
compatibility, this will always print out the officially supported version, which
people _should_ use.

This adds printk messages with basic information about the driver being loaded.
This information includes a summary of the compiled-in features, which
simplifies bug-reporting and debugging a lot.
Also a firmware ID is printed. This is a unique identifier blob for a specific
version of the firmware. This ID is attached to a specific version of the firmware
blob in b43-fwcutter (see fwcutter git).
This helps users to select the right firmware for their device.
This also makes it possible to use automated scripts to fetch and extract the right
firmware for the driver. (the script will grep the .ko for the "Firmware-ID: xxx" string.
While the driver might still support other versions of the firmware for backward
compatibility, this will always print out the officially supported version, which
people _should_ use.

Value of count is used to decide when to replenish rx buffers. If it is
equal or above 8 we replenish the buffers. Ensure there is no starvation
by initializing count to 8 - thus forcing replenish at first iteration.
This is helpful when rx receives batches of buffers smaller than 8.

when setting up the tx descriptors for the hardware we must account for any
padding between the header and the data we might have added previously. frame
len is the length of the frame in the air (including FCS but no padding) and
buffer len is the length of the buffer (including padding, but without FCS).
changing the way ah_setup_tx_desc is called: now excluding the FCS, since it's
easier to add that in the function where we need it.
before this fix we sent trailing zero bytes after the packet (because frame len
included the padding) which was not a big problem without WEP, but with WEP
this resultes in a wrong WEP checksum and the packet is discarded - which is
how i noticed at all ;)
an easy way to run into header padding problems, btw, is to connect to a QoS
(WME) enabled access point (eg. madwifi) - QoS data frames are 2 byte longer
and will require padding.

This is the central patch of a cleanup series. In most cases there is no good
reason why someone would want to use a dentry for itself. This series reflects
that fact and embeds a struct path into nameidata.
Together with the other patches of this series
- it enforced the correct order of getting/releasing the reference count on
<dentry,vfsmount> pairs
- it prepares the VFS for stacking support since it is essential to have a
struct path in every place where the stack can be traversed
- it reduces the overall code size:

There's an undesirable interaction with issuing MRA requests to
increase connection timeouts and the listen backlog.
When the rdma_cm receives a connection request, it queues an MRA with
the ib_cm. (The ib_cm will send an MRA if it receives a duplicate
REQ.) The rdma_cm will then create a new rdma_cm_id and give that to
the user, which in this case is the rdma_user_cm.
If the listen backlog maintained in the rdma_user_cm is full, it
destroys the rdma_cm_id, which in turns destroys the ib_cm_id. The
ib_cm_id generates a REJ because the state of the ib_cm_id has changed
to MRA sent, versus REQ received. When the backlog is full, we just
want to drop the REQ so that it is retried later.
Fix this by deferring queuing the MRA until after the user of the
rdma_cm has examined the connection request.

mlx4_table_find (for FMR MPTs) requires that ICM memory already be
mapped. Before this fix, FMR allocation depended on ICM memory
already being mapped for the MPT entry. If all currently mapped
entries are taken, the find operation fails (even if the MPT ICM table
still had more entries, which were just not mapped yet).
This fix moves the mpt find operation to fmr_enable, to guarantee that
any required ICM memory mapping has already occurred.

In P_Key event handling, if the old P_Key is no longer available, the
driver must call ipoib_ib_dev_stop() -- just as it does when the P_Key
is still available (see procedure __ipoib_ib_dev_flush()).
When a P_Key becomes available, the driver will perform ipoib_open(),
which assumes that the QP is in RESET, the cm_id has been
destroyed/deleted, etc. If ipoib_ib_dev_stop() is not called as
described above, then these assumptions will be false, and the attempt
to bring the interface up will fail.

This helps in identifying the exact hardware C-states behind the ACPI C-state
definition.
Idea is to export this through powertop, which will help to map the C-state
reported by powertop to actual hardware C-state.

Earlier patch (bc71bec91f) broke
suspend resume on many laptops. The problem was reported by
Carlos R. Mafra and Calvin Walton, who bisected the issue to above patch.
The problem was because, C2 and C3 code were calling acpi_idle_enter_c1
directly, with C2 or C3 as state parameter, while suspend/resume was in
progress. The patch bc71bec started making use of that state information,
assuming that it would always be referring to C1 state. This caused the
problem with suspend-resume as we ended up using C2/C3 state indirectly.
Fix this by adding acpi_idle_suspend check in enter_c1.

Arjan:
With the help of kerneloops.org I've spotted a nice little interaction
between the TTY layer and the bluetooth code, however the tty layer is not
something I'm all too familiar with so I rather ask than brute-force fix the
code incorrectly.
The raw details are at:
http://www.kerneloops.org/search.php?search=uart_flush_buffer
What happens is that, on closing the bluetooth tty, the tty layer goes
into the release_dev() function, which first does a bunch of stuff, then
sets the file->private_data to NULL, does some more stuff and then calls the
ldisc close function. Which in this case, is hci_uart_tty_close().
Now, hci_uart_tty_close() calls hci_uart_close() which clears some
internal bit, and then calls hci_uart_flush()... which calls back to the
tty layers' uart_flush_buffer() function. (in drivers/bluetooth/hci_tty.c
around line 194) Which then WARN_ON()'s because that's not allowed/supposed
to be called this late in the shutdown of the port....
Should the bluetooth driver even call this flush function at all??
David:
This seems to be what happens: Hci_uart_close() flushes using
hci_uart_flush(). Subsequently, in hci_dev_do_close(), (one step in
hci_unregister_dev()), hci_uart_flush() is called again. The comment in
uart_flush_buffer(), relating to the WARN_ON(), indicates you can't flush
after the port is closed; which sounds reasonable. I think hci_uart_close()
should set hdev->flush to NULL before returning. Hci_dev_do_close() does
check for this. The code path is rather involved and I'm not entirely clear
of all steps, but I think that's what should be done.

Commit 9af57b7a ("IB/cm: Add basic performance counters") introduced a
bug in how the reference count for cm_class.subsys.kobj was handled:
the path that released a device did a kobject_put() on that kobject, but
there was no kobject_get() in the path the handles adding a device. So
the reference count ended up too low, which leads to bad things. Fix up
and simplify the reference counting to avoid this.
(Actually, I introduced the bug when fixing the patch up to match some
of Greg's kobject changes, but who's counting)

The MegaRAID driver's common management module (megaraid_mm.c) creates a
char device used by the management tool "megarc" from LSI Logic (and
possibly other management tools).
In 2.6 with udev, this device doesn't get created because it is not
registered in sysfs.
I first fixed this by registering a class "megaraid_mm", but realized that
this should probably be moved to misc devices, instead of taking up a char
major. This is because only 1 device is used, even if there are multiple
adapters - the minor is never used (the adapter info is in the ioctl block
sent to the driver, not detected based on the minor number as one might
think). So it is a complete waste to have an entire major taken by this.
So it now uses a misc device which I named "megadev0" (the name that megarc
expects), and has a dynamic minor (previoulsy a dynamic major was used).
I have tested this on my own system with the megarc tool, and it works just
as fine as before (only now the device gets created correctly by udev).

advansys crashes. The hostdata is placed on a sizeof(unsigned long)
boundary so the 8 byte boundary is not garanteed with x86_32.

Add a mutex to serialise access to the chip functions from
entries such as the ethtool and the MII code. This should
reduce the amount of time the spinlock is held to protect
the address register.

The srom array in the board data is only being used in the device probe
routines. The probe also only uses the first 6 bytes of an array
we spend 512ms reading 128 bytes from. Change to reading the
MAC area directly to the MAC address structure.
As a side product, we rename the read_srom_word to dm9000_read_eeprom
to bring it into line with the rest of the driver. No change is made
to the delay in this function, which will be dealt with in a later
patch.

We can use sleeping functions when reading and writing the
PHY registers, so let us sleep instead of busy waiting for
the PHY.
Note, this also fixes a bug reading the PHY where only 100uS
was being used instead of 150uS

The phy read and write routines call udelay() with the board
lock held, and with the posibility of IRQs being disabled. Since
these delays can be up to 500usec, and are only required as we
have to save the chip's address register.
To improve the behaviour, hold the lock whilst we are writing
and then restore the state before the delay and then repeat
the process once the delay has happened.

Remove the timer based MII phy polling, as this is
currently broken with the new EEPROM code that now
uses mutexes to protect the phy access.
This will need to be replaced in the future by some
form of mutex safe mechanism for reading the MII
phy status.
The replacement has not been done here as changing
this patch, which is early in the sequence has quite
a knock-on effect. Once this series is merged, then
a new presentation of an patch to poll the MII link
status can be added.

Use the flags in the IRQ resource to specify the type of
IRQ being requested, so that systems which do not have
level-based interrupts, or change the interrupt in some
other way can specify this without making an #ifdef mess
in the driver.
This is specifically designed to undo the change in commit
4e4fc05a2b which hardwires the
type for everyone but blackfin to IRQT_RISING, which breaks
all a number of Simtec boards which use (and setup in the
bootloader) active low IRQs.
Note, although there where originally objections due to
the use of IORESOURCE_IRQ and IRQT_ flags not sharing the
same definition, at least <include/linux/interrupt.h> notes
these are the same.

1. Add common code for stopping queue.
2. No need to call netif_stop_queue followed by netif_wake_queue (and
infact a netif_start_queue could have been used instead), instead
call stop_queue if required, and remove code under USE_GTS macro.
3. There is no need to check for netif_queue_stopped, as the network
core guarantees that for us (I am sure every driver could remove
that check, eg e1000 - I have tested that path a few billion times
with about a few hundred thousand qstops but the condition never
hit even once).
