Pull TTY updates from Greg Kroah-Hartman:
"Here's the big TTY/serial driver pull request for the 3.5-rc1 merge
window.
Nothing major in here, just lots of incremental changes from Alan and
Jiri reworking some tty core things to behave better and to get a more
solid grasp on some of the nasty tty locking issues.
There are a few tty and serial driver updates in here as well.
All of this has been in the linux-next releases for a while with no
problems.

Pull driver core updates from Greg Kroah-Hartman:
"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.

Pull USB 3.5-rc1 changes from Greg Kroah-Hartman:
"Here is the big USB 3.5-rc1 pull request for the 3.5-rc1 merge window.
It's touches a lot of different parts of the kernel, all USB drivers,
due to some API cleanups (getting rid of the ancient err() macro) and
some changes that are needed for USB 3.0 power management updates.
There are also lots of new drivers, pimarily gadget, but others as
well. We deleted a staging driver, which was nice, and finally
dropped the obsolete usbfs code, which will make Al happy to never
have to touch that again.
There were some build errors in the tree that linux-next found a few
days ago, but those were fixed by the most recent changes (all were
due to us not building with CONFIG_PM disabled.)

Pull arm-soc board specific changes from Olof Johansson:
"While we generally attempt to get rid of board specific files and
replace them with device tree based descriptions, a lot of platforms
have not come that far:
In shmobile, we add two new board files because their recently started
effort to add DT support has not proceeded enough to use it for all of
the important hardware.
In Kirkwood, we are adding support for new boards with a combination
of DT and board file contents in multiple cases.

adding new ones."

Pull arm soc-specific pinctrl changes from Olof Johansson:
"With this, five platforms are moving to the relatively new pinctrl
subsystem for their pin management, replacing the older soc specific
in-kernel interfaces with common code.
There is quite a bit of net addition of code for each platform being
added to the pinctrl subsystem. But the payback comes later when
adding new boards can be done by only providing new device trees
instead."

Pull support for new arm SoCs from Olof Johansson:
"Three new system-on-chip models are supported: the st-ericsson u9540
in ux500, the sam9n12 in at91 and the emma ev2 in shmobile.
Emma is a little bit special because it is completely unrelated to the
classic shmobile models, but the new Renesas rmobile SoCs are a
combination of things from both Emma and shmobile, so it was decided
to have them all live in one directory.
This also contains updates to existing shmobile soc code as well as
some related board changes due to dependencies."

Pull device tree conversions for arm-soc, part 1, from Olof Johansson:
"The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game
of booting using device trees, which is a great step forward for them.
at91 and spear have pretty much completed this process with a huge
amount of work being put into at91. The other platforms are
continuing the process.
We finally start to see the payback on this investment, as new
machines are getting supported purely by adding a .dts source file
that can be completely independent of the kernel source."

Pull first batch of arm-soc cleanups from Olof Johansson:
"These cleanups are basically all over the place. The idea is to
collect changes with minimal impact but large number of changes so we
can avoid them from distracting in the diffstat in the other series.
A significant number of lines get removed here, in particular because
the ixp2000 and ixp23xx platforms get removed. These have never been
extremely popular and have fallen into disuse over time with no active
maintainer taking care of them. The u5500 soc never made it into a
product, so we are removing it from the ux500 platform.
Many good cleanups also went into the at91 and omap platforms, as has
been the case for a number of releases."

If the file that OUTPUT_MIN_CONFIG exists then ktest.pl will prompt the
user and ask them if the OUTPUT_MIN_CONFIG should be used as the
starting point for make_min_config instead of MIN_CONFIG.
This is usually the case, and to allow the user to do so, which is
helpful if the user is creating different min configs based on tests,
and they know one is a superset of another test, they can set
USE_OUTPUT_MIN_CONFIG to one, which will prevent kest.pl from prompting
to use the OUTPUT_MIN_CONFIG and it will just use it.
If USE_OUTPUT_MIN_CONIFG is set to zero, then ktest.pl will continue to
use MIN_CONFIG instead.
The default is that USE_OUTPUT_MIN_CONFIG is undefined.

If we reset the virtio-blk device before the requests already dispatched
to the virtio-blk driver from the block layer are finised, we will stuck
in blk_cleanup_queue() and the remove will fail.
blk_cleanup_queue() calls blk_drain_queue() to drain all requests queued
before DEAD marking. However it will never success if the device is
already stopped. We'll have q->in_flight[] > 0, so the drain will not
finish.
How to reproduce the race:
1. hot-plug a virtio-blk device
2. keep reading/writing the device in guest
3. hot-unplug while the device is busy serving I/O
Test:
~1000 rounds of hot-plug/hot-unplug test passed with this patch.
Changes in v3:
- Drop blk_abort_queue and blk_abort_request
- Use __blk_end_request_all to complete request dispatched to driver
Changes in v2:
- Drop req_in_flight
- Use virtqueue_detach_unused_buf to get request dispatched to driver

Current index allocation in virtio is based on a monotonically
increasing variable "index". This means we'll run out of numbers
after a while. E.g. someone crazy doing this in host side.
while(1) {
hot-plug a virtio device
hot-unplug the virito devcie

restore_common() was used when there were different thaw and freeze PM
callbacks implemented. We removed thaw in commit
f38f8387cbdc4138a492ce9f2a5f04fd3cd3cf33.
restore_common() can be removed and virtballoon_restore() can itself do
the restore ops.

When a virtio_9p pci device is being removed, we should close down any
active channels and free up resources, we're not supposed to BUG() if there's
still an open channel since it's a valid case when removing the PCI device.
Otherwise, removing the PCI device with an open channel would cause the
following BUG():

"This is the v3.5 RCU tree from Paul E. McKenney:
1) A set of improvements and fixes to the RCU_FAST_NO_HZ feature (with
more on the way for 3.6). Posted to LKML:
https://lkml.org/lkml/2012/4/23/324 (commits 1-3 and 5),
https://lkml.org/lkml/2012/4/16/611 (commit 4),

https://lkml.org/lkml/2012/5/4/410 (commit 7, combined with
the other commits for the convenience of the tester).
2) Changes to make rcu_barrier() avoid disrupting execution of CPUs
that have no RCU callbacks. Posted to LKML:
https://lkml.org/lkml/2012/4/23/322.
3) A couple of commits that improve the efficiency of the interaction
between preemptible RCU and the scheduler, these two being all that
survived an abortive attempt to allow preemptible RCU's
__rcu_read_lock() to be inlined. The full set was posted to LKML at
https://lkml.org/lkml/2012/4/14/143, and the first and third patches
of that set remain.
4) Lai Jiangshan's algorithmic implementation of SRCU, which includes
call_srcu() and srcu_barrier(). A major feature of this new
implementation is that synchronize_srcu() no longer disturbs the
execution of other CPUs. This work is based on earlier
implementations by Peter Zijlstra and Paul E. McKenney. Posted to
LKML: https://lkml.org/lkml/2012/2/22/82.

This reverts commit 8c01a529b861ba97c7d78368e6a5d4d42e946f75.
It turns out the d_unhashed() check isn't unnecessary after all: while
it's true that unhashing will increment the sequence numbers, that does
not necessarily invalidate the RCU lookup, because it might have seen
the dentry pointer (before it got unhashed), but by the time it loaded
the sequence number, it could have seen the *new* sequence number (after
it got unhashed).
End result: we might look up an unhashed dentry that is about to be
freed, with the sequence number never indicating anything bad about it.
So checking that the dentry is still hashed (*after* reading the sequence
number) is indeed the proper fix, and was never unnecessary.

Pull usb-gadget scsi-target merge from Nicholas Bellinger:
"As promised, here is the pull request for Sebastian's usb-gadget
target UASP / BOT driver for v3.5-rc1. This code has been in
linux-next for a number of weeks, and is now ready for an initial
merge.
This fabric uses the target framework to provide a usb gadget device.
This gadget supports the USB Attached SCSI Protocol (UASP) and Bulk
Only Transfers (BOT or BBB). BOT is the primary interface, UAS is the
alternative interface.
Note this series is dependent upon a single target core patch for
adding se_cmd->unknown_data_length in target-pending/for-next, that
got merged in the parent.
Kudos to Sebastian for making this driver happen so easily, and for
his patches to improve usb-core and target core along the way to his
goal. Also thanks to Felipe + Greg-KH for their help in getting this
driver ready for mainline."

Pull scsi-target changes from Nicholas Bellinger:
"There has been lots of work in existing code in a number of areas this
past cycle. The major highlights have been:
* Removal of transport_do_task_sg_chain() from core + fabrics
(Roland)
* target-core: Removal of se_task abstraction from target-core and
enforce hw_max_sectors for pSCSI backends (hch)
* Re-factoring of iscsi-target tx immediate/response queues (agrover)
* Conversion of iscsi-target back to using target core memory
allocation logic (agrover)
We've had one last minute iscsi-target patch go into for-next to
address a nasty regression bug related to the target core allocation
logic conversion from agrover that is not included in friday's
linux-next build, but has been included in this series.
On the new fabric module code front for-3.5, here is a brief status
update for the three currently in flight this round:
* usb-gadget target driver:
Sebastian Siewior's driver for supporting usb-gadget target mode
operation. This will be going out as a separate PULL request from
target-pending/usb-target-merge with subsystem maintainer ACKs. There
is one minor target-core patch in this series required to function.
* sbp ieee-1394/firewire target driver:
Chris Boot's driver for supportting the Serial Block Protocol (SBP)
across IEEE-1394 Firewire hardware. This will be going out as a
separate PULL request from target-pending/sbp-target-merge with two
additional drivers/firewire/ patches w/ subsystem maintainer ACKs.
* qla2xxx LLD target mode infrastructure changes + tcm_qla2xxx:
The Qlogic >= 24xx series HW target mode LLD infrastructure patch-set
and tcm_qla2xxx fabric driver. Support for FC target mode using
qla2xxx LLD code has been officially submitted by Qlogic to James
below, and is currently outstanding but not yet merged into
scsi.git/for-next..
[PATCH 00/22] qla2xxx: Updates for scsi "misc" branch
http://www.spinics.net/lists/linux-scsi/msg59350.html
Note there are *zero* direct dependencies upon this for-next series
for the qla2xxx LLD target + tcm_qla2xxx patches submitted above, and
over the last days the target mode team has been tracking down an
tcm_qla2xxx specific active I/O shutdown bug that appears to now be
almost squashed for 3.5-rc-fixes."

Pull regulator updates from Mark Brown:
"The major thing here is the addition of some helpers to factor code
out of drivers, making a fair proportion of regulators much more just
data rather than code which is nice.
- Helpers in the core for regulators using regmap, providing generic
implementations of the enable and voltage selection operations which
just need data to describe them in the drivers.
- Split out voltage mapping and voltage setting, allowing many more
drivers to take advantage of the infrastructure for selectors.
- Loads and loads of cleanups from Axel Lin once again, including many
changes to take advantage of the above new framework features
- New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI
TPS65913, TI TWL6035 and TI TWL6037.
Some of the registration changes to support the core refactoring
caused so many conflicts that eventually topic branches were abandoned
for this release."

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown:
"A surprisingly large series of updates for regmap this time, mostly
due to all the work Stephen Warren has done to add support for MMIO
buses. This wasn't really the target for the framework but it turns
out that there's a reasonable number of cases where it's very helpful
to use the register cache support to allow the register map to remain
available while the device is suspended.
- A MMIO bus implementation, contributed by Stephen Warren. Currently
this is limited to 32 bit systems and native endian registers.
- Support for naming register maps, mainly intended for MMIO devices
with multiple register banks. This was also contributed by Stephen
Warren.
- Support for register striding, again contributed by Stephen Warren
and mainly intended for use with MMIO as typically the registers
will be a fixed size but byte addressed.
- irqdomain support for the generic regmap irq_chip, including support
for dynamically allocate interrupt numbers.
- A function dev_get_regmap() which allows frameworks using regmap to
obtain the regmap for a device from the struct device, making life a
little simpler for them.
- Updates to regmap-irq to support more chips (contributed by Graeme
Gregory) and to use irqdomains.
- Support for devices with 24 bit register addresses.
The striding support collided with all the topic branches so the
branches look a bit messy and eventually I just gave up. There's also
the TI Palmas driver and a couple of other isolated MFD patches that
all depend on new regmap features so are being merged here."
