Pull input layer updates from Dmitry Torokhov:
"2nd round of updates for the input subsystem. With it input core no
longer limits number of character devices per event handler (such as
evdev) to 32, but switches to dynamic minors once legacy range is
exhausted. This should get multi-seat installations that currently
run our of event devices very quickly.
You will also get an update for Wacom driver and a couple of driver
fixes."

The device had an undocumented "feature": it can provide a sequence of
spurious link-down status data even if the link is up all the time.
A sequence of 10 was seen so update the link state only after the device
reports the same link state 20 times.

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
Pull Xen fixes from Konrad Rzeszutek Wilk:
"This has four bug-fixes and one tiny feature that I forgot to put
initially in my tree due to oversight.
The feature is for kdump kernels to speed up the /proc/vmcore reading.
There is a ram_is_pfn helper function that the different platforms can
register for. We are now doing that.
The bug-fixes cover some embarrassing struct pv_cpu_ops variables
being set to NULL on Xen (but not baremetal). We had a similar issue
in the past with {write|read}_msr_safe and this fills the three
missing ones. The other bug-fix is to make the console output (hvc)
be capable of dealing with misbehaving backends and not fall flat on
its face. Lastly, a quirk for older XenBus implementations that came
with an ancient v3.4 hypervisor (so RHEL5 based) - reading of certain
non-existent attributes just hangs the guest during bootup - so we
take precaution of not doing that on such older installations.
Feature:
- Register a pfn_is_ram helper to speed up reading of /proc/vmcore.
Bug-fixes:
- Three pvops call for Xen were undefined causing BUG_ONs.
- Add a quirk so that the shutdown watches (used by kdump) are not
used with older Xen (3.4).
- Fix ungraceful state transition for the HVC console."
* tag 'stable/for-linus-3.7-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen:
xen/pv-on-hvm kexec: add quirk for Xen 3.4 and shutdown watches.
xen/bootup: allow {read|write}_cr8 pvops call.
xen/bootup: allow read_tscp call for Xen PV guests.
xen pv-on-hvm: add pfn_is_ram helper for kdump
xen/hvc: handle backend CLOSED without CLOSING

The commit 254d1a3f02ebc10ccc6e4903394d8d3f484f715e, titled
"xen/pv-on-hvm kexec: shutdown watches from old kernel" assumes that the
XenBus backend can deal with reading of values from:
"control/platform-feature-xs_reset_watches":
... a patch for xenstored is required so that it
accepts the XS_RESET_WATCHES request from a client (see changeset
23839:42a45baf037d in xen-unstable.hg). Without the patch for xenstored
the registration of watches will fail and some features of a PVonHVM
guest are not available. The guest is still able to boot, but repeated
kexec boots will fail."
Sadly this is not true when using a Xen 3.4 hypervisor and booting a PVHVM
guest. We end up hanging at:
err = xenbus_scanf(XBT_NIL, "control",
"platform-feature-xs_reset_watches", "%d", &supported);
This can easily be seen with guests hanging at xenbus_init:
NX (Execute Disable) protection: active
SMBIOS 2.4 present.
DMI: Xen HVM domU, BIOS 3.4.0 05/13/2011
Hypervisor detected: Xen HVM
Xen version 3.4.
Xen Platform PCI: I/O protocol version 1
... snip ..
calling xenbus_init+0x0/0x27e @ 1
Reverting the commit or using the attached patch fixes the issue. This fix
checks whether the hypervisor is older than 4.0 and if so does not try to
perform the read.

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull second set of media updates from Mauro Carvalho Chehab:
"Despite its size, most of the stuff here is trivial. This series
contains:
- s5p-mfc: additions at the driver and at the core to support H.264
hardware codec;
- Some improvements at s5p and davinci embedded drivers;
- Some V4L2 compliance fixes applied on a few drivers;
- Several random trivial patches, including several fixes and a few
new board support additions;
Notes:
1) Some Exynos media patches were dependent on some -arm fixes that
got merged on changeset 782cd9e. That's why this pull request is
based that changeset.
2) As promised, I reviewed the pending VB2 DMABUF series.
While setting a test environment, it was noticed that the upstream
support for Samsung Exynos 4 boards (smdk310 and Origen) are
broken upstream, likely due to regressions: both defconfigs are
wrong and regulator settings for both boards are broken. That,
allied with some bug at the dummy regulator driver, causes OOPSes
during boot time.
Long story short: even fixing the above, the proposed patches
OOPSed when running the DMABUF test. Not sure yet if the OOPSes
are due to some other undetected regressions, or due to some bug
on the patches.
Due to the above, DMABUF patches for vb2 got NACKed for 3.7."

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull second set of pinctrl patches from Linus Walleij:
"Here is a late pinctrl pull request with stuff that wasn't quite
tested at the first pull request.
The main reason to not hold off is that the modifications to
irq_domain_add_simple() as reviewed by Rob Herring introduce new
infrastructure for irqdomains that will be useful for the next cycle:
instead of sprinkling irq descriptor allocation all over the kernel
wherever a "legacy" domain is registered, which is necessary for any
platform using sparse IRQs, and many irq chips are say GPIO
controllers which may be used with several systems, some with sparse
IRQs some not, we push this into the irq_domain_add_simple() so we can
atleast do mistakes in one place.
The irq_domain_add_simple() is currently unused in the kernel, so I
need to provide a user. The Nomadik stuff that goes with are changes
to the driver I use day-to-day to make use of this facility (and a
dependency), so see it as a way to eat my own dogfood: if this blows
up the egg hits my face.
A second round of pinctrl patches for v3.7:
- Complement the Nomadik pinctrl driver with alternate Cx functions
so it handles all oddities.
- A patch to the IRQdomain to reform the simple irqdomain to handle
IRQ descriptor allocation dynamically.
- Use the above feature in the Nomadik pin controller."

Prepare second set of updates for 3.7 merge window (Wacom driver update
and patches extending number of input minors).
|
|
This patch originated from Hiroaki SHIMODA but has been modified
by Intel with some minor cleanups and additional commit log text.
Denys Fedoryshchenko and others reported Tx stalls on e1000e with
BQL enabled. Issue was root caused to hardware delays. They were
introduced because some of the e1000e hardware with transmit
writeback bursting enabled, waits until the driver does an
explict flush OR there are WTHRESH descriptors to write back.
Sometimes the delays in question were on the order of seconds,
causing visible lag for ssh sessions and unacceptable tx
completion latency, especially for BQL enabled kernels.
To avoid possible Tx stalls, change WTHRESH back to 1.
The current plan is to investigate a method for re-enabling
WTHRESH while not harming BQL, but those patches will be later
for net-next if they work.
please enqueue for stable since v3.3 as this bug was introduced in

Pull i2c-embedded changes from Wolfram Sang:
"The changes for i2c-embedded include:
- massive rework of the omap driver
- massive rework of the at91 driver. In fact, the old driver gets
removed; I am okay with this approach since the old driver was
depending on BROKEN and its limitations made it practically
unusable, so people used bitbanging instead. But even if there are
users, there is no platform_data or module parameter which would
need to be converted. It is just another driver doing I2C
transfers, just way better. Modifications of arch/arm/at91 related
files have proper acks from the maintainer.
- new driver for R-Car I2C
- devicetree and generic_clock conversions and fixes
- usual driver fixes and changes.
The rework patches have come a long way and lots of people have been
involved in creating/testing them. Most patches have been in
linux-next at least since 3.6-rc5. A few have been added in the last
week, I have to admit.
An unexpected (but welcome :)) peak in private life is the cause for
that. The "late" patches shouldn't cause any merge conflicts and I
will have a special eye on them during the stabilization phase. This
is an exception and I want to have the patches in place properly in
time again for the next kernels."

Pull block IO update from Jens Axboe:
"Core block IO bits for 3.7. Not a huge round this time, it contains:
- First series from Kent cleaning up and generalizing bio allocation
and freeing.
- WRITE_SAME support from Martin.
- Mikulas patches to prevent O_DIRECT crashes when someone changes
the block size of a device.
- Make bio_split() work on data-less bio's (like trim/discards).
- A few other minor fixups."
Fixed up silent semantic mis-merge as per Mikulas Patocka and Andrew
Morton. It is due to the VM no longer using a prio-tree (see commit
6b2dbba8b6ac: "mm: replace vma prio_tree with an interval tree").
So make set_blocksize() use mapping_mapped() instead of open-coding the
internal VM knowledge that has changed.

Commit 6b8029fab641 ("rtc: kconfig: remove unnecessary dependencies")
removed various 'depends on RTC_CLASS' dependencies but also removed a
few 'default RTC_CLASS' statements, which actually changed default
behavior.
This resulted in the various RTC interfaces (sysfs, proc, dev) all being
disabled by default, even when RTC_CLASS is enabled:
# CONFIG_RTC_INTF_SYSFS is not set
# CONFIG_RTC_INTF_PROC is not set
# CONFIG_RTC_INTF_DEV is not set
which is different from previous behavior (all of these where enabled.)
To fix, add back the 'default RTC_CLASS' statments to each of the
RTC_INTF_* options.
I noticed this because some RTC tests started failing on my TI OMAP
platforms because /dev/rtc0 was not present anymore, even though the
driver was present and RTC_CLASS was enabled.

John W. Linville says:
====================
Here is a batch of fixes intended for 3.7...
Amitkumar Karwar provides a couple of mwifiex fixes to correctly
report some reason codes for certain connection failures. He also
provides a fix to cleanup after a scanning failure. Bing Zhao rounds
that out with another mwifiex scanning fix.
Daniel Golle gives us a fix for a copy/paste error in rt2x00.
Felix Fietkau brings a couple of ath9k fixes related to suspend/resume,
and a couple of fixes to prevent memory leaks in ath9k and mac80211.
Ronald Wahl sends a carl9170 fix for a sleep in softirq context.
Thomas Pedersen reorders some code to prevent drv_get_tsf from being
called while holding a spinlock, now that it can sleep.
Finally, Wei Yongjun prevents a NULL pointer dereference in the
ath5k driver.
Please let me know if there are problems!

The virq_disabled flag tracks the userspace view of INTx masking
across interrupt mode changes, but we're not consistently applying
this to the interrupt and masking handler notion of the device.
Currently if the user sets DisINTx while in MSI or MSIX mode, then
returns to INTx mode (ex. rebooting a qemu guest), the hardware has
DisINTx+, but the management of INTx thinks it's enabled, making it
impossible to actually clear DisINTx. Fix this by updating the
handler state when INTx is re-enabled.

We need to be ready to recieve an interrupt as soon as we call
request_irq, so our eventfd context setting needs to be moved
earlier. Without this, an interrupt from our device or one
sharing the interrupt line can pass a NULL into eventfd_signal
and oops.

Pull pwm changes from Thierry Reding:
"All legacy PWM providers have now been moved to the PWM subsystem.
The plan for 3.8 is to adapt all board files to provide a lookup table
for PWM devices in order to get rid of the global namespace.
Subsequently, users of the legacy pwm_request() and pwm_free()
functions can be migrated to the new pwm_get() and pwm_put()
functions. Once this has been completed, the legacy API and the
compatibility code in the core can be removed.
In addition to the above, these changes also add support for
configuring the polarity of a PWM signal (currently only supported on
ECAP and EHRPWM) and include a much needed rework of the i.MX driver.
Managed functions to obtain and release a PWM device (devm_pwm_get()
and devm_pwm_put()) have been added and the pwm-backlight driver has
been updated to use them. If the PWM subsystem hasn't been enabled,
dummy functions are provided that allow the subsystem to safely
compile out.
Some common checks on input parameters have been moved to the core and
removed from the drivers. Finally, a small fix corrects the
description of the PWM specifier's second cell in the device tree
representation."

Pull scsi target updates from Nicholas Bellinger:
"Things have been calm for the most part with no new fabric drivers in
flight for v3.7 (we're up to eight now !), so this update is primarily
focused on addressing a few long-standing items within target-core and
iscsi-target fabric code.
The highlights include:
- target: Simplify fabric sense data length handling (roland)
- qla2xxx: Fix endianness of task management response code (roland)
- target: fix truncation of mode data, support zero allocation length
(paolo)
- target: Properly support zero-length commands in normal processing
path (paolo)
- iscsi-target: Correctly set 0xffffffff field within ISCSI_OP_REJECT
PDU (ronnie + nab)
- iscsi-target: Add explicit set of cache_dynamic_acls=1 for TPG
demo-mode (ronnie + nab)
- target/file: Re-enable optional fd_buffered_io=1 operation (nab +
hch)
- iscsi-target: Add MaxXmitDataSegmenthLength forr target ->
initiator MDRSL declaration (nab)
- target: Add target_submit_cmd_map_sgls for SGL fabric memory
passthrough (nab + hch)
- tcm_loop: Convert I/O path to use target_submit_cmd_map_sgls (hch +
nab)
- tcm_vhost: Convert I/O path to use target_submit_cmd_map_sgls (nab
+ hch)
The last series for adding a new target_submit_cmd_map_sgls() fabric
caller (as requested by hch) that accepts pre-allocated SGL memory
(using existing logic), along with converting tcm_loop + tcm_vhost has
only been in -next for the last days, but has gotten enough review
+testing and is clear enough a mechanical change that I think it's
reasonable to merge for -rc1 code.
Thanks again to everyone who contributed this round! Extra special
thanks to Roland (PureStorage) for tracking down the qla2xxx target
TMR response code endian issue, and to Paolo (Redhat) for resolving
the long standing zero-length CDB issues within target-core between
virtual and pSCSI backends."
