Here's the big tty/serial tree set of changes for 3.8-rc1.
Contained in here is a bunch more reworks of the tty port layer from Jiri and
bugfixes from Alan, along with a number of other tty and serial driver updates
by the various driver authors.
Also, Jiri has been coerced^Wconvinced to be the co-maintainer of the TTY
layer, which is much appreciated by me.
All of these have been in the linux-next tree for a while.

Fixed up some trivial conflicts in the staging tree, due to the fwserial
driver having come in both ways (but fixed up a bit in the serial tree),
and the ioctl handling in the dgrp driver having been done slightly
differently (staging tree got that one right, and removed both
TIOCGSOFTCAR and TIOCSSOFTCAR).

After commit "TTY: move tty buffers to tty_port", the tty buffers are
not freed in some drivers. This is because tty_port_destructor is not
called whenever a tty_port is freed. This was an assumption I counted
with but was unfortunately untrue. So fix the drivers to fulfil this
assumption.
To be sure, the TTY buffers (and later some stuff) are gone along with
the tty_port, we have to call tty_port_destroy at tear-down places.
This is mostly where the structure containing a tty_port is freed.
This patch does exactly that -- put tty_port_destroy at those places.

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.

A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA,
currently it lost original meaning but still has some effects:
| effect | alternative flags
-+------------------------+---------------------------------------------
1| account as reserved_vm | VM_IO
2| skip in core dump | VM_IO, VM_DONTDUMP
3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
This patch removes reserved_vm counter from mm_struct. Seems like nobody
cares about it, it does not exported into userspace directly, it only
reduces total_vm showed in proc.
Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP.
remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP.
remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

Pull workqueue changes from Tejun Heo:
"This is workqueue updates for v3.7-rc1. A lot of activities this
round including considerable API and behavior cleanups.
* delayed_work combines a timer and a work item. The handling of the
timer part has always been a bit clunky leading to confusing
cancelation API with weird corner-case behaviors. delayed_work is
updated to use new IRQ safe timer and cancelation now works as
expected.
* Another deficiency of delayed_work was lack of the counterpart of
mod_timer() which led to cancel+queue combinations or open-coded
timer+work usages. mod_delayed_work[_on]() are added.
These two delayed_work changes make delayed_work provide interface
and behave like timer which is executed with process context.
* A work item could be executed concurrently on multiple CPUs, which
is rather unintuitive and made flush_work() behavior confusing and
half-broken under certain circumstances. This problem doesn't
exist for non-reentrant workqueues. While non-reentrancy check
isn't free, the overhead is incurred only when a work item bounces
across different CPUs and even in simulated pathological scenario
the overhead isn't too high.
All workqueues are made non-reentrant. This removes the
distinction between flush_[delayed_]work() and
flush_[delayed_]_work_sync(). The former is now as strong as the
latter and the specified work item is guaranteed to have finished
execution of any previous queueing on return.
* In addition to the various bug fixes, Lai redid and simplified CPU
hotplug handling significantly.
* Joonsoo introduced system_highpri_wq and used it during CPU
hotplug.
There are two merge commits - one to pull in IRQ safe timer from
tip/timers/core and the other to pull in CPU hotplug fixes from
wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."
Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.
Tejun pointed out a few of them, I fixed a couple more.

is now settled down and working properly, so we are ready for 3.7-rc1.

firmware file and adding a staging tty driver (it depended on the tty

tree.)

Merge tag 'tty-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull TTY changes from Greg Kroah-Hartman:
"As we skipped the merge window for 3.6-rc1 for the tty tree,
everything is now settled down and working properly, so we are ready
for 3.7-rc1. Here's the patchset, it's big, but the large changes are
removing a firmware file and adding a staging tty driver (it depended
on the tty core changes, so it's going through this tree instead of
the staging tree.)
All of these patches have been in the linux-next tree for a while.

Add lis3lv02d device tree initialization code/API to take pdata from
device node. Also adds device tree init matching table support to
lis3lv02d_i2c driver. If the driver data is passed from device tree, then
this driver picks up platform data from device node through common/generic

pci_disable_device(pdev) used to be in pci remove function. But this
PCI device has two functions with interrupt lines connected to a
single pin. The other one is a USB host controller. So when we disable
the PIN there e.g. by rmmod hpilo, the controller stops working. It is
because the interrupt link is disabled in ACPI since it is not
refcounted yet. See acpi_pci_link_free_irq called from
acpi_pci_irq_disable.
It is not the best solution whatsoever, but as a workaround until the
ACPI irq link refcounting is sorted out this should fix the reported
errors.

Commit 002176db (misc: at25: Parse dt settings) added device tree
bindings the differ significantly in style from the I2C EEPROM
bindings and don't seem well vetted. Here I deprecate (but still
support) the "at25,*" properties, and add what I hope is a better
alternative. These new bindings also happen to be deployed in the
field and were previously submitted for consideration here:
https://lists.ozlabs.org/pipermail/devicetree-discuss/2012-May/015556.html
The advantages of the new bindings are that they are similar to the
I2C EEPROMs and they don't conflate read-only and the address width
modes in a binary encoded blob.

On many of our larger systems, CPU 0 has had all of its IRQ resources
consumed before XPC loads. Worst cases on machines with multiple 10
GigE cards and multiple IB cards have depleted the entire first socket
of IRQs.
This patch makes selecting the node upon which IRQs are allocated (as
well as all the other GRU Message Queue structures) specifiable as a
module load param and has a default behavior of searching all nodes/cpus
for an available resources.

flush[_delayed]_work_sync() are now spurious. Mark them deprecated

If you're cc'd and wondering what's going on: Now all workqueues are
non-reentrant and the regular flushes guarantee that the work item is
not pending or running on any CPU on return, so there's no reason to
use the sync flushes at all and they're going away.

Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI:
centralize controller initialization") that clashed with commit
2761a63945 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix
issues").
In particular, commit 2761a63945 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).
I left that part of commit 2761a63945 just undone.

Pull PWM subsystem from Thierry Reding:
"The new PWM subsystem aims at collecting all implementations of the
legacy PWM API and to eventually replace it completely.
The subsystem has been in development for over half a year now and
many drivers have already been converted. It has been in linux-next
for a couple of weeks and there have been no major issues so I think
it is ready for inclusion in your tree."
Arnd Bergmann <arnd@arndb.de>:
"Very much Ack on the new subsystem. It uses the interface
declarations as the previously separate pwm drivers, so nothing
changes for now in the drivers using it, although it enables us to
change those more easily in the future if we want to.
This work is also one of the missing pieces that are required to
eventually build ARM kernels for multiple platforms, which is
currently prohibited (amongs other things) by the fact that you cannot
have more than one driver exporting the pwm functions."

In order to avoid duplicate symbols with legacy PWM API implementations,
the new PWM framework needs to conflict with any of the existing legacy
implementations. This is done in two ways: for implementations provided
by drivers, a conflict is added to the driver to ensure it will have to
be ported to the PWM subsystem before it can coexist with other PWM
providers. For architecture-specific code, the conflict is added to the
PWM symbol to avoid confusion when a previously picked platform or
machine can no longer be selected because of the PWM subsystem being
included.

The code here has a nested spin_lock_irqsave(). It's not needed since
IRQs are already disabled and it causes a problem because it means that
IRQs won't be enabled again at the end. The second call to
spin_lock_irqsave() will overwrite the value of irq_flags and we can't
restore the proper settings.

Here is the big staging tree pull request for the 3.5-rc1 merge window.
Loads of changes here, and we just narrowly added more lines than we
added:
622 files changed, 28356 insertions(+), 26059 deletions(-)
But, good news is that there is a number of subsystems that moved out of
the staging tree, to their respective "real" portions of the kernel.
Code that moved out was:
- iio core code
- mei driver
- vme core and bridge drivers
There was one broken network driver that moved into staging as a step
before it is removed from the tree (pc300), and there was a few new
drivers added to the tree:
- new iio drivers
- gdm72xx wimax USB driver
- ipack subsystem and 2 drivers
All of the movements around have acks from the various subsystem
maintainers, and all of this has been in the linux-next tree for a
while.

Fixed up various trivial conflicts, along with a non-trivial one found
in -next and pointed out by Olof Johanssen: a clean - but incorrect -
merge of the arch/arm/boot/dts/at91sam9g20.dtsi file. Fix up manually
as per Stephen Rothwell.

Here's the driver core, and other driver subsystems, pull request for
the 3.5-rc1 merge window.
Outside of a few minor driver core changes, we ended up with the
following different subsystem and core changes as well, due to
interdependancies on the driver core:
- hyperv driver updates
- drivers/memory being created and some drivers moved into it
- extcon driver subsystem created out of the old Android staging switch
driver code
- dynamic debug updates
- printk rework, and /dev/kmsg changes
All of this has been tested in the linux-next releases for a few weeks
with no reported problems.

This patch remove old max8997-muic drvier because of newly Extcon framework.
Extcon framework manages the external connector, so add extcon-max8997 driver
by using Extcon interface to support MUIC feature of Maxim 8997 PMIC instead
of max8997-muic driver(drivers/misc/max8997-muic.c).
