Kill an unused member of the i2c_adapter structure.  This additionally
fixes a potential bug, because <linux/i2c.h> doesn't include
<linux/config.h>, so different files including <linux/i2c.h> could see a
different definition of the i2c_adapter structure, depending on them
including <linux/config.h> (or other header files themselves including
<linux/config.h>) before <linux/i2c.h>, or not.

3eddddcf23 [PATCH] uml: breakpoint an arbitrary thread
This patch implements a stack trace for a thread, not unlike sysrq-t does.
The advantage to this is that a break point can be placed on showreqs, so that
upon showing the stack, you jump immediately into the debugger.  While sysrq-t
does the same thing, sysrq-t shows *all* threads stacks.  It also doesn't work
right now.  In the future, I thought it might be acceptable to make this show
all pids stacks, but perhaps leaving well enough alone and just using sysrq-t
would be okay.  For now, upon receiving the stack command, UML switches
context to that thread, dumps its registers, and then switches context back to
the original thread.  Since UML compacts all threads into one of 4 host
threads, this sort of mechanism could be expanded in the future to include
other debugging helpers that sysrq does not cover.

Note by jdike - The main benefit to this is that it brings an arbitrary thread
back into context, where it can be examined by gdb.  The fact that it dumps it
stack is secondary.  This provides the capability to examine a sleeping
thread, which has existed in tt mode, but not in skas mode until now.

Also, the other threads, that sysrq doesn't cover, can be gdb-ed directly
anyway.

67e6b62921 [DCCP]: Introduce DCCP_SOCKOPT_SERVICE
As discussed in the dccp@vger mailing list:

Now applications have to use setsockopt(DCCP_SOCKOPT_SERVICE, service[s]),
prior to calling listen() and connect().

An array of unsigned ints can be passed meaning that the listening sock accepts
connection requests for several services.

With this we can ditch struct sockaddr_dccp and use only sockaddr_in (and
sockaddr_in6 in the future).

1b3cb73f73 [ARM] Tighten pfn_valid() test.
Thomas Gleixner reported that mmaping and unmapping each physical
page in turn eventually caused the kernel to oops.  It appears
that pfn_valid() in the discontigmem case was too simplistic for
proper operation.

Tighten the logic so we also check if the PFN is within the range
of the selected memory node.

917afce100 [ARM] 2911/1: ixp2000_reg_{read,write} accessors
Patch from Lennert Buytenhek

This patch:
- changes the ixp2000_reg_write accessor to take a 'volatile void *'
  instead of a 'volatile unsigned long *', which then allows passing in
  a u32 * as first argument without being greeted with a warning; and
- adds an ixp2000_reg_read accessor.
We can then use these accessors in ixp2000 code to access on-chip
peripherals, instead of directly dereferencing pointers.  This is for
use by the ixp2000 microengine driver which was recently announced on
netdev.  We can't use readl/writel on the ixp2000 since it is usually
run in big-endian mode, and on big-endian platforms, readl/writel
perform byteswapping.
A future patch will remove the readback from ixp2000_reg_write, since
it's not needed to prevent erratum #66, and add manual readbacks to the
places that need them (writes are not synchronous since we map in device
space using XCB=101 nowadays), such as interrupt disabling and GPIO
manipulation.  See also:

87375ab47c [IPVS]: ip_vs_ftp breaks connections using persistence
ip_vs_ftp when loaded can create NAT connections with unknown client
port for passive FTP. For such expectations we lookup with cport=0 on
incoming packet but it matches the format of the persistence templates
causing packets to other persistent virtual servers to be forwarded to
real server without creating connection. Later the reply packets are
treated as foreign and not SNAT-ed.

This patch changes the connection lookup for packets from clients:

* introduce IP_VS_CONN_F_TEMPLATE connection flag to mark the
  connection as template

* create new connection lookup function just for templates -
  ip_vs_ct_in_get

* make sure ip_vs_conn_in_get hits only connections with
  IP_VS_CONN_F_NO_CPORT flag set when s_port is 0. By this way
  we avoid returning template when looking for cport=0 (ftp)

Fix the build of the RME32 and RME96 drivers by having them use the

PCI_DEVICE_ID_xxx names that they used to define themselves.

name is PCI_DEVICE_ID_RME_DIGI96_8_PAD_OR_PST.

9db455064d [PATCH] v4l: experimental Sliced VBI API support
Adds all defines, ioctls and structs needed for the sliced VBI API

VBI = Vertical Blank Interval.

It is related with the way TV signals work.  It sends a line, then, it has a
retrace time to allow the tube to move electrons to the beginning of the next
line.  This was the main reason at the beginning of analog B&W TV.

There is a lot of bandwidth lost on VBI.  So, lots of TV systems use it to
send other information such as Closed Captions and Teletext.  Also,
broadcasters uses this as a channel to exchange information from the content
producer to their subsidiaries at each city.

There's already a raw VBI interface on V4L2 api, used for Closed Captions and
Teletext.  The decoding is doing at userlevel space and it is mostly for
analog TV signals, non encoded.

Encoded signals (MPEG, for example), may need also to transmit other
information (like, for example, display aspect, i.e.  4x3, widescreen...).
Sliced VBI interface is a method to allow the video stream to transmit this
kind of information.

Sharp's newer range of Zaurus clamshell handhelds, the cxx00's are similar to
the c7x0 series yet different.  This patch series abstracts the differences
and generates a set of common drivers that support both series of devices.  It
then adds machine support for Spitz (SL-C3000) and Borzoi (SL-C3100).  Hooks
for Akita (SL-C1000) differences are also added.  The I2C driver for its IO
expander is the only missing piece.

This patch:

Separate out the Sharp Zaurus c7x0 series specific code from corgi_ssp.c so
that other models such as the cxx00's can share it.  Create sharpsl.h which
will be used to abstract machine/model specifics.

This enables the driver to be used by the Zaurus cxx00 series.

9dc7a86e85 [PATCH] cciss: new controller pci/subsystem ids
This patch adds new PCI and subsystem ID's that finally made the spec.  It
also include a name change for one controller.  I know there's a lot of
duplicat names but the fw folks wanted this for the different implementations.

Even though the same ASIC is used it may be embedded on some platforms,
standup card in others, and a mezzanine in other servers.

498d0c5711 [PATCH] set_current_state() commentary
Explain the mysteries of set_current_state().

Quoth Linus:

 The scheduler itself never needs the memory barrier at all.

 The barrier is needed only if the user itself ends up testing some other
 thing afterwards, ie if you have

 	set_process_state(TASK_INTERRUPTIBLE);
 	if (still_need_to_sleep())
 		schedule();

 then the "still_need_to_sleep()" thing may test flags and wakeup events,
 and then you _may_ want to (and often do) make sure that the write of
 TASK_INTERRUPTIBLE is serialized wrt the reads of any wakeup data (since
 the wakeup may have happened on another CPU).

 So the comment is somewhat wrong. We don't really _care_ whether the state
 propagates out to other CPU's since all of our actions are purely local,
 and there is nothing we do that is conditional on any other CPU: we're
 going to sleep unconditionally, and the scheduler only cares about _our_
 state, not about somebody elses state.

921717a2a1 [PATCH] Make BUILD_BUG_ON fail at compile time.
Force a compiler error instead of a link error, because they are easier to
track down.  Idea stolen from code by Jan Beulich <jbeulich@novell.com>

If the argument to BUILD_BUG_ON evaluates to non-zero the compiler will do:

	t.c:6: error: size of array `type name' is negative

(surprised that gcc doesn't have an extension for this)
