8) SCTP socket option wasn't extended in a backwards compatible way,
fix from Thomas Graf.
9) Add missing address change event emissions to bonding, from Shlomo
Pongratz.
10) /proc/net/dev regressed because it uses a private offset to track
where we are in the hash table, but this doesn't track the offset
pullback that the seq_file code does resulting in some entries being
missed in large dumps.
Fix from Eric Dumazet.
11) do_tcp_sendpage() unloads the send queue way too fast, because it
invokes tcp_push() when it shouldn't. Let the natural sequence
generated by the splice paths, and the assosciated MSG_MORE
settings, guide the tcp_push() calls.
Otherwise what goes out of TCP is spaghetti and doesn't batch
effectively into GSO/TSO clusters.
From Eric Dumazet.
12) Once we put a SKB into either the netlink receiver's queue or a
socket error queue, it can be consumed and freed up, therefore we
cannot touch it after queueing it like that.
Fixes from Eric Dumazet.
13) PPP has this annoying behavior in that for every transmit call it
immediately stops the TX queue, then calls down into the next layer
to transmit the PPP frame.
But if that next layer can take it immediately, it just un-stops the
TX queue right before returning from the transmit method.
Besides being useless work, it makes several facilities unusable, in
particular things like the equalizers. Well behaved devices should
only stop the TX queue when they really are full, and in PPP's case
when it gets backlogged to the downstream device.
David Woodhouse therefore fixed PPP to not stop the TX queue until
it's downstream can't take data any more.
14) IFF_UNICAST_FLT got accidently lost in some recent stmmac driver
changes, re-add. From Marc Kleine-Budde.
15) Fix link flaps in ixgbe, from Eric W. Multanen.
16) Descriptor writeback fixes in e1000e from Matthew Vick.

A bunch of fixes for regressions (and a few other problems) in 3.4-rc1:
* Fix for regression of mach/io.h cleanup on platforms with PCI or PCMCIA
(adding back the include file on those for now)
* AT91 fixes for usb and spi
* smsc911x ethernet fixes for i.MX
* smsc911x fixes for OMAP
* gpio fixes for Tegra
* A handful of build error and warning fixes for various platforms
* cpufreq kconfig dependencies, build and lowlevel debug fixes for
Samsung platforms
In other words, more or less the regular collection of -rc1/2 type
material. A few of them, in particular the smsc911x for OMAP series, aren't
technically regressions for 3.4, but they're valid fixes and we're still
relatively early in the rc cycle so it seems appropriate to include them.

When a slave comes up, we're unsetting the current_arp_slave without
removing active flags from it, which can lead to situations where we have

To avoid this situation we must remove the active flags from a slave before
removing it as a current_arp_slave.

Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op. This leads to a
proliferation of the default_open() implementation across the entire

Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().
This replacement was done with the following semantic patch:

Change send_sig_all() to use do_send_sig_info(SEND_SIG_FORCED) instead
of force_sig(SIGKILL). With the recent changes we do not need force_ to
kill the CLONE_NEWPID tasks.
And this is more correct. force_sig() can race with the exiting thread,
while do_send_sig_info(group => true) kill the whole process.
Some more notes from Oleg Nesterov:
> Just one note. This change makes no difference for sysrq_handle_kill().
> But it obviously changes the behaviour sysrq_handle_term(). I think
> this is fine, if you want to really kill the task which blocks/ignores
> SIGTERM you can use sysrq_handle_kill().
>
> Even ignoring the reasons why force_sig() is simply wrong here,
> force_sig(SIGTERM) looks strange. The task won't be killed if it has
> a handler, but SIG_IGN can't help. However if it has the handler
> but blocks SIGTERM temporary (this is very common) it will be killed.
Also,
> force_sig() can't kill the process if the main thread has already
> exited. IOW, it is trivial to create the process which can't be
> killed by sysrq.
So, this patch fixes the issue.

The driver uses a 2-order allocation, which is too much on architectures
like ppc64, which has a 64KiB page. This particular allocation is used
for large packet fragments that may have a size of 512, 1024, 4096 or
fill the whole allocation. So, a minimum size of 16384 is good enough
and will be the same size that is used in architectures of 4KiB sized
pages.
This will avoid allocation failures that we see when the system is under
stress, but still has plenty of memory, like the one below.
This will also allow us to set the interface MTU to higher values like
9000, which was not possible on ppc64 without this patch.

Pull DMA mapping branch from Marek Szyprowski:
"Short summary for the whole series:
A few limitations have been identified in the current dma-mapping
design and its implementations for various architectures. There exist
more than one function for allocating and freeing the buffers:
currently these 3 are used dma_{alloc, free}_coherent,
dma_{alloc,free}_writecombine, dma_{alloc,free}_noncoherent.
For most of the systems these calls are almost equivalent and can be
interchanged. For others, especially the truly non-coherent ones
(like ARM), the difference can be easily noticed in overall driver
performance. Sadly not all architectures provide implementations for
all of them, so the drivers might need to be adapted and cannot be
easily shared between different architectures. The provided patches
unify all these functions and hide the differences under the already
existing dma attributes concept. The thread with more references is
available here:
http://www.spinics.net/lists/linux-sh/msg09777.html
These patches are also a prerequisite for unifying DMA-mapping
implementation on ARM architecture with the common one provided by
dma_map_ops structure and extending it with IOMMU support. More
information is available in the following thread:
http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819
More works on dma-mapping framework are planned, especially in the
area of buffer sharing and managing the shared mappings (together with
the recently introduced dma_buf interface: commit d15bd7ee44
"dma-buf: Introduce dma buffer sharing mechanism").
The patches in the current set introduce a new alloc/free methods
(with support for memory attributes) in dma_map_ops structure, which
will later replace dma_alloc_coherent and dma_alloc_writecombine
functions."
People finally started piping up with support for merging this, so I'm
merging it as the last of the pending stuff from the merge window.
Looks like pohmelfs is going to wait for 3.5 and more external support
for merging.

laser is controller by GPIO, after 1.60.xx drivers were previously loaded.
On these designs the TX_LASER is enabled by logic AND between the PHY

MDIO part, hence the GPIO control had no affect de facto.

Modified from original patch from Chris.
The sky2 driver has to have 8 byte alignment of receive buffer
on some chip versions. On architectures which don't support efficient
unaligned access this doesn't work very well. The solution is to
just copy all received packets which is what the driver already
does for small packets.
This allows the driver to be used on the Tilera TILEmpower-Gx, since
the tile architecture doesn't currently handle kernel unaligned accesses,
just userspace.

The current implemenation was buggy for slaves who use ndo_neigh_setup,
since the networking stack invokes the bonding device ndo entry (from
neigh_params_alloc) before any devices are enslaved, and the bonding
driver can't further delegate the call at that point in time. As a
result when bonding IPoIB devices, the neigh_cleanup hasn't been called.
Fix that by deferring the actual call into the slave ndo_neigh_setup
from the time the bonding neigh_setup is called.

commit 7d26bb103c "bonding: emit event when bonding changes MAC" didn't
take care to emit the NETDEV_CHANGEADDR event in bond_release, where bonding
actually changes the mac address (to all zeroes). As a result the neighbours
aren't deleted by the core networking code (which does so upon getting that
event).

* Patch series that hopefully fixes races between the freezer and request_firmware()

* Runtime PM fix from Alan Stern preventing tasks from getting stuck indefinitely
in the runtime PM wait queue.
* Device PM QoS update from MyungJoo Ham introducing a new variant of
