Conflicts:
MAINTAINERS
drivers/net/wireless/iwlwifi/pcie/trans.c
The iwlwifi conflict was resolved by keeping the code added
in 'net' that turns off the buggy chip feature.
The MAINTAINERS conflict was merely overlapping changes, one
change updated all the wireless web site URLs and the other
changed some GIT trees to be Johannes's instead of John's.

Add dev_loopback_xmit() in order to deduplicate functions
ip_dev_loopback_xmit() (in net/ipv4/ip_output.c) and
ip6_dev_loopback_xmit() (in net/ipv6/ip6_output.c).
I was about to reinvent the wheel when I noticed that
ip_dev_loopback_xmit() and ip6_dev_loopback_xmit() do exactly what I
need and are not IP-only functions, but they were not available to reuse
elsewhere.
ip6_dev_loopback_xmit() does not have line "skb_dst_force(skb);", but I
understand that this is harmless, and should be in dev_loopback_xmit().

Routing of 127/8 is tradtionally forbidden, we consider
packets from that address block martian when routing and do
not process corresponding ARP requests.
This is a sane default but renders a huge address space
practically unuseable.
The RFC states that no address within the 127/8 block should
ever appear on any network anywhere but it does not forbid
the use of such addresses outside of the loopback device in
particular. For example to address a pool of virtual guests
behind a load balancer.
This patch adds a new interface option 'route_localnet'
enabling routing of the 127/8 address block and processing
of ARP requests on a specific interface.
Note that for the feature to work, the default local route
covering 127/8 dev lo needs to be removed.
Example:
$ sysctl -w net.ipv4.conf.eth0.route_localnet=1
$ ip route del 127.0.0.0/8 dev lo table local
$ ip addr add 127.1.0.1/16 dev eth0
$ ip route flush cache

In a PCI environment, transactions aren't always required to reach
the root bus before being re-routed. Intermediate switches between
an endpoint and the root bus can redirect DMA back downstream before
things like IOMMUs have a chance to intervene. Legacy PCI is always
susceptible to this as it operates on a shared bus. PCIe added a
new capability to describe and control this behavior, Access Control
Services, or ACS.
The utility function pci_acs_enabled() allows us to test the ACS
capabilities of an individual devices against a set of flags while
pci_acs_path_enabled() tests a complete path from a given downstream
device up to the specified upstream device. We also include the
ability to add device specific tests as it's likely we'll see
devices that do not implement ACS, but want to indicate support
for various capabilities in this space.

This patch resolves potential issues when accessing PCI Express
Capability structures. The makeup of the capability varies
substantially between v1 and v2:
Version 1 of the PCI Express Capability (defined by PCI Express
1.0 and 1.1 base) neither requires the endpoint to implement the
entire PCIe capability structure nor specifies default values of
registers that are not implemented by the device.
Version 2 of the PCI Express Capability (defined by PCIe 1.1
Capability Structure Expansion ECN, PCIe 2.0, 2.1, and 3.0) added
additional registers to the structure and requires all registers
to be either implemented or hardwired to 0.
Due to the differences in the capability structures, code dealing with
capability features must be careful not to access the additional
registers introduced with v2 unless the device is specifically known to
be a v2 capable device. Otherwise, attempts to access non-existant
registers will occur. This is a subtle issue that is hard to track down
when it occurs (and it has - see commit 864d296cf94).
To try and help mitigate such occurrences, this patch introduces
pci_pcie_cap2() which is similar to pci_pcie_cap() but also checks
that the PCIe capability version is >= 2. pci_pcie_cap2() should be
used for qualifying PCIe capability features introduced after v1.

DMA transactions are tagged with the source ID of the device making
the request. Occasionally hardware screws this up and uses the
source ID of a different device (often the wrong function number of
a multifunction device). A specific Ricoh multifunction device is
a prime example of this problem and included in this patch.
Given a pci_dev, this function returns the pci_dev to use as the
source ID for DMA. When hardware works correctly, this returns
the input device. For the components of the Ricoh multifunction
device, it returns the pci_dev for function 0.
This will be used by IOMMU drivers for determining the boundaries
of IOMMU groups as multiple devices using the same source ID must
be contained within the same group. This can also be used by
existing streaming DMA paths for the same purpose.

Yuck. The VIDIOC_(TRY_)DECODER_CMD ioctls already had ioctl numbers 96 and 97,
and after merging the timings API I forgot to continue numbering from 98. So
now we have two ioctls with number 96 and two with 97.
With the new table-driver ioctl handling in v4l2-ioctl.c it is essential that
each ioctl has its own unique number, so let's fix this quickly for 3.5.

Now that idle and nohz logics are going to be independant each others,
ts->idle_tick becomes too much a biased name to describe the field that
saves the last scheduled tick on top of which we re-calculate the next
tick to schedule when the timer is restarted.
We want to reuse this even to stop the tick outside idle cases. So let's
rename it to some more generic name: ts->last_tick.
This changes a bit the timer list stat export so we need to increase its
version.

Kernel kobjects have rigid rules: each container object should be
dynamically allocated, and can't be allocated into a single kmalloc.
EDAC never obeyed this rule: it has a single malloc function that
allocates all needed data into a single kzalloc.
As this is not accepted anymore, change the allocation schema of the
EDAC *_info structs to enforce this Kernel standard.

The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:
$ tree /sys/bus/edac/

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

The existing seq_printf function is rewritten in terms of the new
seq_vprintf which is also exported to modules. This allows GFS2
(and potentially other seq_file users) to have a vprintf based
interface and to avoid an extra copy into a temporary buffer in
some cases.

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/urgent
Merge RCU fixes from Paul E. McKenney:
" This series has four patches, the major point of which is to eliminate
some slowdowns (including boot-time slowdowns) resulting from some
RCU_FAST_NO_HZ changes. The issue with the changes is that posting timers
from the idle loop has no effect if the CPU has entered dyntick-idle
mode because the CPU has already computed its wakeup time, and posting
a timer does not cause it to be recomputed. The short-term fix is for
RCU to precompute the timeout value so that the CPU's calculation is
correct. "

pxa-ssp.c uses API like cpu_is_pxa3xx(), cpu_is_pxa2xx(), which is
defined under arch-pxa architecture, and drivers under mach-mmp
can't find it. so just use ssp->type to replace that API.

This patch adds regulator_set_voltage_time_sel(), to move into core, the
commonly used code by drivers to provide the .set_voltage_time_sel callback.
It will also allow us to configure different ramp delay for different
regulators easily.

I originally sent this patch to <trivial@kernel.org>, but Jiri Kosina did
not feel that this is fully appropriate for the trivial tree.
Using linux/tcp.h from C++ results in:
cat t.cc
#include <linux/tcp.h>
int main() { }
g++ -c t.cc
In file included from t.cc:1:
/usr/include/linux/tcp.h:72: error: '__u32 __fswab32(__u32)' cannot appear in a constant-expression
/usr/include/linux/tcp.h:72: error: a function call cannot appear in a constant-expression
...
Attached trivial patch fixes this problem.
Tested:
- the t.cc above compiles with g++ and
- the following program generates the same output before/after
the patch:
#include <linux/tcp.h>
#include <stdio.h>
int main ()
{
#define P(a) printf("%s: %08x\n", #a, (int)a)
P(TCP_FLAG_CWR);
P(TCP_FLAG_ECE);
P(TCP_FLAG_URG);
P(TCP_FLAG_ACK);
P(TCP_FLAG_PSH);
P(TCP_FLAG_RST);
P(TCP_FLAG_SYN);
P(TCP_FLAG_FIN);
P(TCP_RESERVED_BITS);
P(TCP_DATA_OFFSET);
#undef P
return 0;

Since it's guarenteed that we will access the inetpeer if we're trying
to do timewait recycling and TCP options were enabled on the
connection, just cache the peer in the timewait socket.
In the future, inetpeer lookups will be context dependent (per routing
realm), and this helps facilitate that as well.

Convert calculations of proportion of writeback each bdi does to new flexible
proportion code. That allows us to use aging period of fixed wallclock time
which gives better proportion estimates given the hugely varying throughput of
different devices.

Implement code computing proportions of events of different type (like code in
lib/proportions.c) but allowing periods to have different lengths. This allows
us to have aging periods of fixed wallclock time which gives better proportion
estimates given the hugely varying throughput of different devices - previous
measuring of aging period by number of events has the problem that a reasonable
period length for a system with low-end USB stick is not a reasonable period
length for a system with high-end storage array resulting either in too slow
proportion updates or too fluctuating proportion updates.
