When using numa=fake= you can get weird topologies where LLCs can span
nodes and other such nonsense. Cure this by hard partitioning these

The target allows you to create rules in the "raw" and "mangle" tables
which set the skbuff mark by means of hash calculation within a given
range. The nfmark can influence the routing method (see "Use netfilter
MARK value as routing key") and can also be used by other subsystems to
change their behaviour.

This patch adds the flags parameter to ipv6_find_hdr. This flags
allows us to:
* know if this is a fragment.
* stop at the AH header, so the information contained in that header
can be used for some specific packet handling.
This patch also adds the offset parameter for inspection of one
inner IPv6 header that is contained in error messages.

assumption
If we have one cpu that failed to boot and boot cpu gave up on
waiting for it and then another cpu is being booted, kernel
might crash with following OOPS:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000018
IP: [<ffffffff812c3630>] __bitmap_weight+0x30/0x80
Call Trace:
[<ffffffff8108b9b6>] build_sched_domains+0x7b6/0xa50
The crash happens in init_sched_groups_power() that expects
sched_groups to be circular linked list. However it is not
always true, since sched_groups preallocated in __sdt_alloc are
initialized in build_sched_groups and it may exit early
if (cpu != cpumask_first(sched_domain_span(sd)))
return 0;
without initializing sd->groups->next field.
Fix bug by initializing next field right after sched_group was
allocated.

We incorrectly parse incoming IR data. The extra byte contains the upper
bits and not the lower bits of the x/y coordinates. User-space expects
absolute position data from us so this patch does not break existing
applications. On the contrary, it extends the virtual view and fixes
garbage reports for margin areas of the virtual screen.

this pull request contains some device tree work by Lee Jones.
I have tried to keep these patches in the arch/arm/boot/dts/*

There is still one patch that touches arch/arm/mach-ux500 too
though (but it should merge fine with the other ux500 stuff).
The changes to the device tree are of course dependent on some
core changes and some patching in the GPIO/pin driver, but as
the device tree files are believed to be a different world
(and should one day live in their own git) I split this off
anyway. I don't think people bisect the device trees per se

As a prerequisite for merging the lpc32xx DT changes, this
pulls in the depends/i2c/lpc32xx branch that contains
changes to the pnx-i2c driver, which are already in the
i2c tree. The branch is available also on
git://git.antcom.de/linux-2.6.git lpc32xx/i2c
Roland Stigge <stigge@antcom.de> writes:
this is the series of the 4 patches adding device tree support to i2c-pnx
(used by LPC32xx) that Wolfram Sang already applied to the i2c subsystem.
Since both drivers/i2c/ and mach-lpc32xx are touched here, there will
probably be conflicts that you need to be aware of.
I'm posting this again for arm-soc since the actual mach-lpc32xx specific
DT conversion builds upon those changes (see next pull request), especially
in arch/arm/mach-lpc32xx/common.c.
Wolfram already gave permission to merge this via arm-soc, but please
coordinate and tell me if I can help resolving this.
Further, this implicitly updates the next/dt branch to v3.4-rc4, which
causes a trivial conflict from a change in one branch in code that
gets removed in another.

The regulators in the twl4030 can provide some voltage settings
that are not offically supported.
These settings are disabled by default, but can be enabled with
CONFIG_TWL4030_ALLOW_UNSUPPORTED=y
However
- that config variable is not mentioned in any Kconfig so cannot
be used, and
- a global setting is clumsy - a per regulator setting would be
better.
So define a new 'feature' flag that a board file can set to enable
these unsupported volatages for boards which need them.
This flag cannot (yet) be set using device-tree.

twl-regulator has a collection of feature flags, some defined
in twl-core.c and one defined in i2c/twl.h.
This is confusing for anyone adding a new feature flag.
So collect them together and place them in twl.h immediately
after the structure in which they are initially set.

When an IRQ for some reason gets lost, we wait up to a second using
udelay, which is CPU intensive. This patch improves the situation by
waiting about 30 ms in the CPU intensive mode, then stepping down to
using msleep(2) instead. In essence, we trade some granularity in
exchange for less CPU consumption when the waiting time is a bit longer.
As a result, PulseAudio should no longer be killed by the kernel
for taking up to much RT-prio CPU time. At least not for *this* reason.

In preparation for device tree, this patch changes how the DSI pins are
configured. The current configuration method is only doable with board
files and the configuration data is OMAP specific.
This patch moves the configuration data to the panel's platform data,
and the data can easily be given via DT in the future. The configuration
data format is also changed to a generic one which should be suitable
for all platforms.
The new format is an array of pin numbers, where the array items start
from clock + and -, then data1 + and -, and so on. For example:
{
0, // pin num for clock lane +
1, // pin num for clock lane -
2, // pin num for data1 lane +
3, // pin num for data1 lane -
...
}
The pin numbers are translated by the DSI driver and used to configure
the hardware appropriately.

The driver for the TFP410 chip should handle the power-down signal of
the chip, instead of the current way of handling it in the board files.
This patch adds power_down_gpio into the device's platform data, and
adds the necessary code in the driver to request and handle the GPIO.

This patch introduces a new mesh configuration parameter "ht_opmode" and will
allow user to check the current HT protection mode selected. Users could
configure the protection mode by the command "iw mesh_iface set mesh_param
mesh_ht_protection_mode=2". The default protection mode of mesh is set to
non-HT mixed mode.

Section 9.23.3.5 of IEEE 80211s standard describes the protection rules for
HT mesh STA in a MBSS. Three HT protection modes are supported for now:
non-HT mixed mode - is selected if any non-HT peers are present in our MBSS.
20MHz-protection mode - is selected if all peers in our 20/40MHz MBSS support
HT and atleast one HT20 peer is present.
no-protection mode - is selected otherwise.
This is a limited implementation of 9.23.3.5, which only considers mesh peers
when determining the HT protection mode. Station's channel_type needs to be
maintained.

Since the BSS table is organized in a RB tree, the BSSs need to be
comparable. This means that we must define a < and > operator to
the BSS object.
compare_ethr_addr isn't enough since it returns only a binary value.
Since Felix's
cfg80211: use compare_ether_addr on MAC addresses instead of memcmp
Because of the constant size and guaranteed 16 bit alignment, the inline
compare_ether_addr function is much cheaper than calling memcmp.

The BSS table is corrupted: rb_find_bss can't find the bss.
As a result BSSes are duplicated in the BSS table, and we get stuck
while probing an AP before associating (in STA mode).

Some sdio host controllers do not support real in band interrupt.
Software polling mode as a replacement is not fast enough for
high throughput and new features. Also some in band interrupts
do not support host wake up on embedded platform even when they
are real physical interrupts. Therefore out of band (oob)
interrupt mechanism is implemented for these scenarios.
To provide oob irq number and flags used for irq registration in
brcmfmac, a platform device contains irq resource must be
registered in board specific code.
Here is an example of platform device structure:
struct resource brcmf_sdio_res[] = {
{
.start = GPIO_BRCMF_SDIO_OOB_NUM,
.end = GPIO_BRCMF_SDIO_OOB_NUM,
.flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL,
}
};
struct platform_device brcmf_sdio_device = {
.name = "brcmf_sdio_pd",
.id = -1,
.num_resources = ARRAY_SIZE(brcmf_sdio_res),
.resource = brcmf_sdio_res,
};

For out of band interrupt which is going to be introduced shortly,
the interrupt register function must be called after firmware is

brcmf_sdbrcm_bus_init.
