Defer config changed notifications that arrive during
probe/scan/freeze/restore.
This will allow drivers to set DRIVER_OK earlier, without worrying about
racing with config change interrupts.
This change will also benefit old hypervisors (before 2009)
that send interrupts without checking DRIVER_OK: previously,
the callback could race with driver-specific initialization.
This will also help simplify drivers.

Replace duplicated code in all transports with a single wrapper in
virtio.c.
The only functional change is in virtio_mmio.c: if a buggy device sends
us an interrupt before driver is set, we previously returned IRQ_NONE,
now we return IRQ_HANDLED.
As this must not happen in practice, this does not look like a big deal.

On restore, virtio pci does the following:
+ set features
+ init vqs etc - device can be used at this point!
+ set ACKNOWLEDGE,DRIVER and DRIVER_OK status bits
This is in violation of the virtio spec, which
requires the following order:
- ACKNOWLEDGE
- DRIVER
- init vqs
- DRIVER_OK
This behaviour will break with hypervisors that assume spec compliant
behaviour. It seems like a good idea to have this patch applied to
stable branches to reduce the support butden for the hypervisors.

This patch is to review the whole glue logic adopted on STi SoCs that
was bugged.
In the old glue-logic there was a lot of confusion when setup the
retiming especially for STiD127 where, for example, the bits 6 and 7
(in the GMAC control register) have a different meaning of what is
used for STiH4xx SoCs. So we cannot adopt the same glue for all these
SoCs.
Moreover, GiGa on STiD127 didn't work and, for all the SoCs, the RGMII
couldn't run when the speed was 10Mbps (because the clock was not properly
managed).
Note that the phy clock needs to be provided by the platform as well as
documented in the related binding file (updated as consequence).
The old code supported too many configurations never adopted and validated.
This made the code very complex to maintain and debug in case of issues.
The patch simplifies all the configurations as commented in the tables
inside the file and obviously it has been tested on all the boards
based on the SoCs mentioned.
With this patch, the dwmac-sti is also ready to support new configurations that
will be available on next SoC generations.

These fields may both change while the image is mapped if a snapshot
is created or deleted or the image is resized. They are guarded by
rbd_dev->header_rwsem, so hold that while reading them, and store a
local copy to refer to outside of the critical section. The local copy
will stay consistent since the snapshot context is reference counted,
and the mapping size is just a u64. This prevents torn loads from
giving us inconsistent values.
Move reading header.snapc into the caller of rbd_img_request_create()
so that we only need to take the semaphore once. The read-only caller,
rbd_parent_request_create() can just pass NULL for snapc, since the
snapshot context is only relevant for writes.

In ib_uverbs_open_qp, the sharable xrc target qp is created as a
"pseudo" qp and added to a list of qp's sharing the same physical
QP. This is done before the "pseudo" qp is assigned a uobject.
There is a race condition here if an async event arrives at the
physical qp. If the event is handled after the pseudo qp is added to
the list, but before it is assigned a uobject, the kernel crashes in
ib_uverbs_qp_event_handler, due to trying to dereference a NULL
uobject pointer.
Note that simply checking for non-NULL is not enough, due to error
flows in ib_uverbs_open_qp. If the failure is after assigning the
uobject, but before the qp has fully been created, we still have a
problem.
Thus, in ib_uverbs_qp_event_handler, we test that the uobject is
present, and also that it is live.

The main 'md' thread is needed for processing writes, so if it blocks
write requests could be delayed.
Starting a new thread requires some GFP_KERNEL allocations and so can
wait for writes to complete. This can deadlock.
So instead, ask a workqueue to start the sync thread.
There is no particular rush for this to happen, so any work queue
will do.
MD_RECOVERY_RUNNING is used to ensure only one thread is started.

In general we don't allow an array to be stopped if it is in use.
However if the array hasn't really been started yet, then any
apparent use is an anomily, probably due to 'udev' or similar
having a look to see what is there.
This means that if something goes wrong while assembling an array
it cannot reliably be un-assembled - STOP_ARRAY could fail.
There is no value here, so change do_md_stop() to succeed
despite concurrent opens if the array has not yet been
activated. i.e. if ->pers is NULL.

"This patch set contains the main portion of the changes for 3.18 in
regard to the s390 architecture. It is a bit bigger than usual,
mainly because of a new driver and the vector extension patches.
The interesting bits are:
- Quite a bit of work on the tracing front. Uprobes is enabled and
the ftrace code is reworked to get some of the lost performance
back if CONFIG_FTRACE is enabled.
- To improve boot time with CONFIG_DEBIG_PAGEALLOC, support for the
IPTE range facility is added.
- The rwlock code is re-factored to improve writer fairness and to be
able to use the interlocked-access instructions.
- The kernel part for the support of the vector extension is added.
- The device driver to access the CD/DVD on the HMC is added, this
will hopefully come in handy to improve the installation process.
- Add support for control-unit initiated reconfiguration.
- The crypto device driver is enhanced to enable the additional AP
domains and to allow the new crypto hardware to be used.
- Bug fixes"

drivers/rtc/rtc-pcf8563.c:173:5: warning: 'pending' may be used uninitialized in this function [-Wmaybe-uninitialized]
This is because in the pcf8563_get_alarm_mode() function, we check any
nonzero return of pcf8563_read_block_data, but in the irq function we
only check for negative values, so a possible positive value does not
get detected if the compiler chooses not to inline the entire call
chain.
Checking for any non-zero value in the interrupt handler as well is just
as correct and lets the compiler know what we are doing, without needing
a bogus initialization.

The RTC driver assumes that this will always be true since the PMIC IRQ
is a required property according to the max77686 DT binding doc. If an
"interrupts" property is not defined for a max77686 PMIC, then the mfd
probe function will fail and the RTC platform driver will never be
probed.
But even when it is not possible to probe the rtc-max77686 driver
without a regmap IRQ chip, it's better to explicitly check if the IRQ
chip data is not NULL and gracefully fail instead of getting an OOPS.

The MAX77686 RTC chip has two features called SMPL (Sudden Momentary
Power Loss) and WTSR (Watchdog Timeout and Software Resets). Support
for these features seems to be implemented in the driver but compilation
is disabled using a C pre-processor conditional.
This code has been disabled since the driver was original merged in
commit fca1dd031a ("rtc: max77686: add Maxim 77686 driver").
So, since this code has never been built, let's just remove it.

This series add support for the Real Time clock present in the Maxim 77802
Power Managment IC. The version number is quite high because it
previously was part of a bigger series [0] that aimed to add support for
all the devices in the max77802 PMIC. But now that the max77802
dependencies were already merged for 3.17, the series were split but I
kept the version numbering.
While working on the max77802 rtc support a lot of feedback was given and
the issues pointed out also apply to a driver for a similar PMIC RTC
(max77686). So patches 01/06 to 05/06 in the series are cleanups for the
max77686 driver and patch 06/06 adds the support for the max77802 RTC.
The series were tested on an Exynos5250 Snow (max77686) and
Exynos5420 Peach Pit (max77802) machines.
This patch (of 6):
The max77686 includes an RTC that keeps power during suspend. It's
convenient to be able to use it as a wakeup source.

The old code has problems with the Dell MST monitors due to some
assumptions I made that weren't true.
I initially thought the Virtual Channel Payload IDs had to be in
the DPCD table in ascending order, however it appears that assumption
is bogus.
The old code also assumed it was possible to insert a member
into the table and it would move other members up, like it does
when you remove table entries, however reality has shown this
isn't true.
So the new code allocates VCPIs separate from entries in the payload
tracking table, and when we remove an entry from the DPCD table,
I shuffle the tracking payload entries around in the struct.
This appears to make VT switch more robust (still not perfect)
with an MST enabled Dell monitor.

Active multiplexing is a nice feature as it allows several pointing devices
(such as touchpad and external mouse) use their native protocols at the
same time. Unfortunately many manufacturers do not implement the feature
properly even though they advertise it. The problematic implementations are
never fixed, since Windows by default does not use this mode, and move from
one BIOS/model of laptop to another. When active multiplexing is broken
turning it on usually results in touchpad, keyboard, or both unresponsive.
With PS/2 usage on decline (most of PS/2 devices in use nowadays are
internal laptop touchpads), I expect number of users who have laptops with
working MUX implementation, docking stations with external PS/2 ports, and
who are still using external PS/2 mice, to be rather small. Let's flip the
default to be OFF and allow activating it through i8042.nomux=0 kernel
option. We'll also keep DMI table where we can record known good models.

Unfortunately, ForcePad capability is not actually exported over PS/2, so
we have to resort to DMI checks.

This branch contains bug fixes and new features for the devicetree code.
Most of the changes are either new testcases for the selftest code or
documentation changes. The most notable change is the addition of a
phandle resolver for use when grafting in a second device tree blob into
the core tree. The resolver isn't currently used by anything other than
the selftest module, but it will be used to support device tree
overlays; probably in the v3.19 timeframe.
Also note that I've moved my normal tree from git.secretlab.ca to
git.kernel.org.

Merge tag 'restart-handler-for-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
Pull restart handler infrastructure from Guenter Roeck:
"This series was supposed to be pulled through various trees using it,
and I did not plan to send a separate pull request. As it turns out,
the pinctrl tree did not merge with it, is now upstream, and uses it,
meaning there are now build failures.
Please pull this series directly to fix those build failures"
* tag 'restart-handler-for-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging:
arm/arm64: unexport restart handlers
watchdog: sunxi: register restart handler with kernel restart handler
watchdog: alim7101: register restart handler with kernel restart handler
watchdog: moxart: register restart handler with kernel restart handler
arm: support restart through restart handler call chain
arm64: support restart through restart handler call chain
power/restart: call machine_restart instead of arm_pm_restart
kernel: add support for kernel restart handler call chain
Multiple enable_irq_wake() calls will keep increasing the IRQ
wake_depth, which ultimately leads to the following types of
situation:
1) enable Wake-on-LAN interrupt w/o password
2) enable Wake-on-LAN interrupt w/ password
3) enable Wake-on-LAN interrupt w/o password
4) disable Wake-on-LAN interrupt
After step 4), SYSTEMPORT would always wake-up the system no matter what
wake-up device we use, which is not what we want. Fix this by making
sure there are no unbalanced enable_irq_wake() calls.
