Roel Kluin reported a bug in two error paths where skbs were wrongly

kfree_skb(), as it should be.
However, in i2400mu_rx(), the error path was missing returning an

it to the caller, i2400mu_rxd(). It will be treated as a transient
error and just ignore the packet.
Depending on the buffering conditions inside the device, the data
packet might be dropped or the device will signal the host again for
data-ready-to-read and the host will retry.

net: Fix data corruption when splicing from sockets.
The trick in socket splicing where we try to convert the skb->data
into a page based reference using virt_to_page() does not work so
well.
The idea is to pass the virt_to_page() reference via the pipe
buffer, and refcount the buffer using a SKB reference.
But if we are splicing from a socket to a socket (via sendpage)
this doesn't work.
The from side processing will grab the page (and SKB) references.
The sendpage() calls will grab page references only, return, and
then the from side processing completes and drops the SKB ref.
The page based reference to skb->data is not enough to keep the
kmalloc() buffer backing it from being reused. Yet, that is
all that the socket send side has at this point.
This leads to data corruption if the skb->data buffer is reused
by SLAB before the send side socket actually gets the TX packet
out to the device.
The fix employed here is to simply allocate a page and copy the
skb->data bytes into that page.
This will hurt performance, but there is no clear way to fix this
properly without a copy at the present time, and it is important
to get rid of the data corruption.
With fixes from Herbert Xu.

tg3: Fix firmware loading
This patch modifies how the tg3 driver handles device firmware.
The patch starts by consolidating David Woodhouse's earlier patch under
the same name. Specifically, the patch moves the request_firmware call
into a separate tg3_request_firmware() function and calls that function
from tg3_open() rather than tg3_init_one().
The patch then goes on to limit the number of devices that will make
request_firmware calls. The original firmware patch unnecessarily
requested TSO firmware for devices that did not need it. This patch
reduces the set of devices making TSO firmware patches to approximately
the following device set : 5703, 5704, and 5705.
Finally, the patch reduces the effects of a request_firmware() failure.
For those devices that are requesting TSO firmware, the driver will turn
off the TSO capability. If TSO firmware becomes available at a later
time, the device can be closed and then opened again to reacquire the
TSO capability.

clening up after the underrun makes the driver and the macb hardware

rt2x00: fix a wrong parameter for __test_and_clear_bit() in rt2x00rfkill_free().
When running modprobe rt73usb, and then rmmod rt73usb, and then
iwconfig, the wlan0 device does not disappear. When repeating this
process again, we get a kernel Oops errors and "BUG: unable to handle
kernel paging request..." message in the kernel log.
The reason for this is that there is an error in rt2x00rfkill_free(),
which is called in the process of removing the device
(rt2x00lib_remove_dev() in rt2x00dev.c).
rt2x00rfkill_free() clears the RFKILL_STATE_ALLOCATED bit , which is
bit number 1 () in rt2x00dev->flags instead of in
rt2x00dev->rfkill_state. As a result, when checking the
DEVICE_STATE_REGISTERED_HW bit (bit number 1 in rt2x00dev->flags) in
rt2x00lib_remove_hw() it is **unset**, and we wrongly **don't** call
ieee80211_unregister_hw().
This patch corrects this: the parameter for __test_and_clear_bit() in
rt2x00rfkill_free() should be &rt2x00dev->rfkill_state and not
&rt2x00dev->flags.

cfg80211: Fix regression with 11d on bands
This fixes a regression on disallowing bands introduced with the new
802.11d support. The issue is that IEEE-802.11 allows APs to send
a subset of what a country regulatory domain defines. This was clarified
in this document:
http://tinyurl.com/11d-clarification
As such it is possible, and this is what is done in practice, that a
single band 2.4 GHz AP will only send 2.4 GHz band regulatory information
through the 802.11 country information element and then the current
intersection with what CRDA provided yields a regulatory domain with
no 5 GHz information -- even though that country may actually allow
5 GHz operation. We correct this by only applying the intersection rules
on a channel if the the intersection yields a regulatory rule on the
same band the channel is on.

Btrfs: fix ioctl arg size (userland incompatible change!)
The structure used to send device in btrfs ioctl calls was not
properly aligned, and so 32 bit ioctls would not work properly on
64 bit kernels.
We could fix this with compat ioctls, but we're just one byte away
and it doesn't make sense at this stage to carry about the compat ioctls
forever at this stage in the project.
This patch brings the ioctl arg up to an evenly aligned 4k.

Btrfs: Clear the device->running_pending flag before bailing on congestion
Btrfs maintains a queue of async bio submissions so the checksumming
threads don't have to wait on get_request_wait. In order to avoid
extra wakeups, this code has a running_pending flag that is used
to tell new submissions they don't need to wake the thread.
When the threads notice congestion on a single device, they
may decide to requeue the job and move on to other devices. This
makes sure the running_pending flag is cleared before the
job is requeued.
It should help avoid IO stalls by making sure the task is woken up
when new submissions come in.

Revert "PCI PM: Register power state of devices during initialization"
This reverts commit
98e6e286d7b01deb7453b717aa38ebb69d6cefc0, as Yinghai
Lu reports that it breaks kexec with at least the e1000 and e1000e
drivers. The reason is that the shutdown sequence puts the hardware
into D3 sleep, and the commit causes us to claim that it then is in D0
(running) state just because we don't understand the PM capabilities.
Which then later makes "pci_set_power_state()" not do anything, and the
device never wakes up properly and just returns 0xff to everything.
