Pull networking updates from David Miller:
1) inet6_csk_update_pmtu() must return NULL or non-NULL, so translate
ERR_PTR to NULL, as needed. Fix from Eric Dumazet.
2) Fix copy&paste error in IRDA sir_dev ->set_speed method invocation,
it was testing the NULL'ness of a different method to guard the
call. Fix from Alexander Shiyan.
3) Fix build regression of xilinx driver, from Jeff Mahoney.
4) Make XEN netfront (like XEN netback) handle compound pages in SKBs
properly. From Ian Campbell.
5) Fix inverted logic of team_dev_queue_xmit() return value checks,
from Jiri Pirko and Dan Carpenter.
6) dma_poll_create() no longer allows a NULL device argument, breaking
both ixp4xx drivers. Fix from Xi Wang.
7) ne2000 driver doesn't hook up the parent device properly, breaking
udev matching. Fix from Alan Cox.
8) Locking and memory leak fixes in Near Field Communications layer.
From Thierry Escande, Szymon Janc, and Waldemar Rymarkiewicz.
9) sis900 resume regression, sis900_set_mode() is being called with the
iomem pointer instead of the expected device private. Fix from
Francois Romieu.
10) Fix IBSS regression caused by uninitializing the ibss-internals
before performing an emptyness check, from Simon WUnderlich.
11) Fix SNIFFER mode regression in iwlwifi driver, from Johannes Berg.
12) Fix task wedges in mwifiex_cmd_timeout_func(), from Bing Zhao.
13) Add back wireless sysfs directory, too much stuff depends upon it
being there (actually I'd say it never should have been removed to
begin with). From Johannes Berg.
14) Fix hang introduced by suspend/resume changes in ath9k. Fix from
Sujith Manoharan.

commit 9e44476851e91c86c98eb92b9bc27fb801f89072
MD: raid5 avoid unnecessary zero page for trim
change raid5 to clear R5_Discard when the complete request is
handled rather than when submitting the per-device discard request.
However it did not clear R5_Discard for the parity device.
This means that if the stripe_head was reused before it expired from
the cache, the setting would be wrong and a hang would result.
Also if the R5_Uptodate bit happens to be set, R5_Discard again
won't be cleared. But R5_Uptodate really should be clear at this point.
So make sure R5_Discard is cleared in all cases, and clear
R5_Uptodate when a 'discard' completes.

stripe_handle.
The chunk of code in stripe_handle which responds to a
*_result value in reconstruct_state is really the completion
of some processing that happened outside of handle_stripe
(possibly asynchronously) and so should be one of the first
things done in handle_stripe().
After the next patch it will be important that it happens before
handle_stripe_clean_event(), as that will clear some dev->flags
bit that this code tests.

The STDI block may measure wrong values, especially for lcvs and lcf. If the
driver can not find any valid timing, the STDI block is restarted to measure
the video timings again. The function will return an error, but the restart of
STDI will generate a new STDI interrupt and the format detection process will

Changes the way the primary mode is handled:
- Remove it from platform_data since it doesn't belong there.
- Add a new mode enum for use with s_routing.
- Collapse the two HDMI modes into one HDMI mode: when setting up the
timings manually we do not need to select HDMI_COMP mode. That's only
needed when selecting a preset.
This patch prepares for the next step where we switch to using the presets
where available.

The thing is that team_dev_queue_xmit() returns NET_XMIT_* or -E*.
bc_trasmit() should return true in case all went well. So use ! to get
correct retval from team_dev_queue_xmit() result.

An SKB paged fragment can consist of a compound page with order > 0.
However the netchannel protocol deals only in PAGE_SIZE frames.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into for-davem
John W. Linville says:
====================
This is a batch of fixes intended for 3.7...
Included are two pulls. Regarding the mac80211 tree, Johannes says:
"Please pull my mac80211.git tree (see below) to get two more fixes for
3.7. Both fix regressions introduced *before* this cycle that weren't
noticed until now, one for IBSS not cleaning up properly and the other
to add back the "wireless" sysfs directory for Fedora's startup scripts."
Regarding the iwlwifi tree, Johannes says:
"Please also pull my iwlwifi.git tree, I have two fixes: one to remove a
spurious warning that can actually trigger in legitimate situations, and
the other to fix a regression from when monitor mode was changed to use
the "sniffer" firmware mode."
Also included is an nfc tree pull. Samuel says:
"We mostly have pn533 fixes here, 2 memory leaks and an early unlocking fix.
Moreover, we also have an LLCP adapter linked list insertion fix."
On top of that, a few more bits... Albert Pool adds a USB ID
to rtlwifi. Bing Zhao provides two mwifiex fixes -- one to fix
a system hang during a command timeout, and the other to properly
report a suspend error to the MMC core. Finally, Sujith Manoharan
fixes a thinko that would trigger an ath9k hang during device reset.

The irqs are enabled one-by-one in pm core resume_noirq phase.
This leads to situation where the twl4030 primary interrupt
handler (PIH) is enabled before the chained secondary handlers
(SIH). As the PIH cannot clear the pending interrupt, and
SIHs have not been enabled yet, a flood of interrupts hangs
the device.
Fixed the issue by setting the SIH irqs with IRQF_EARLY_RESUME
flags, so they get enabled before the PIH.

This is a regression introduced by ceb90fa0 (xen/privcmd: add
PRIVCMD_MMAPBATCH_V2 ioctl). It broke xentrace as it used
xc_map_foreign() instead of xc_map_foreign_bulk().
Most code-paths prefer the MMAPBATCH_V2, so this wasn't very obvious
that it broke. The return value is set early on to -EINVAL, and if all
goes well, the "set top bits of the MFN's" never gets called, so the
return value is still EINVAL when the function gets to the end, causing
the caller to think it went wrong (which it didn't!)
Now also including Andres "move the ret = -EINVAL into the error handling
path, as this avoids other similar errors in future.

The correct chip id is 1 since the PWM module is on address 0x49. With the
current TWL6030_MODULE_ID1 the kernel will crash early since we have:
#define TWL6030_MODULE_ID1 0x0E
and
static struct twl_client twl_modules[4];
Down in the stack we try to get the module by:
struct twl_client *twl = &twl_modules[chip];
Which is obviously going to do nasty things.

When the mdio-gpio driver is probed via device trees, the platform
device id is set as -1, However the pdev->id is re-used as bus-id for
while creating mdio gpio bus.
So
For device tree case the mdio-gpio bus name appears as "gpio-ffffffff"
where as
for non-device tree case the bus name appears as "gpio-<bus-num>"
Which means the bus_id is fixed in device tree case, so we can't have
two mdio gpio buses via device trees. Assigning a logical bus number
via device tree solves the problem and the bus name is much consistent
with non-device tree bus name.
Without this patch
1. we can't support two mdio-gpio buses via device trees.
2. we should always pass gpio-ffffffff as bus name to phy_connect, very
different to non-device tree bus name.
So, setting up the bus_id via aliases from device tree is the right
solution and other drivers do similar thing.

md_stop() would stop an array, but not free various attached
data structures.
For internal arrays, these are freed later in do_md_stop() or
mddev_put(), but they don't apply for dm-raid arrays.
So get md_stop() to free them, and only all it from dm-raid.
For internal arrays we now call __md_stop.
