tse_poll() calls __napi_complete() with irq enabled. This leads napi
poll_list corruption and may stop all napi drivers working.
Use napi_complete() instead of __napi_complete().

Pull tty driver reverts from Greg KH:
"Here are some reverts for some tty patches (specifically the pl011
driver) that ended up breaking a bunch of machines (i.e. almost all
of the ones with this chip).
People are working on a fix for this, but in the meantime, it's best
to just revert all 5 patches to restore people's serial consoles.
These reverts have been in linux-next for many days now"

Commit 06bb6f5a69df ("mtd: spi-nor: stop (ab)using struct
spi_device_id") converted an array into a pointer, which means that
we should be checking if the pointer goes anywhere, not whether the C
string is empty. To do the latter means we dereference a NULL pointer
when we reach the terminating entry, for which 'name' is now NULL
instead of an array { 0, 0, ... }.

According to the datasheet[1], both S25FL129P0 (256kB sectors) and
S25FL129P1 (64kB sectors) support dual read, quad read, dual i/o read
and quad i/o read.
I have verified dual read to be working for S25FL129P1 on a dual
capable spi controller. Quad as well as S25FL129P0 is untested, lacking
hardware to verify.

As both omap2 onenand and omap2 nand driver modules are
named the same i.e. "omap2.ko", only one of them gets shipped
during MODPOST if both are configured as loadable modules.
To avoid this ambiguity let's ship the omap2 nand
driver as "omap2_nand.ko"

Pull pwm updates from Thierry Reding:
"This set of changes introduces the beginnings of a new API that's
based around the concept of states that can be atomically applied.
Drivers go to various lengths to implement something similar, which
indicates that the core should really be providing the necessary
framework.
On top of that, there is a bit of cleanup as well as improved
kerneldoc and integration into the device-drivers DocBook.
Regarding drivers there is a new one for the NXP LPC18xx family of
SoCs and a couple of fixes for existing drivers (pca9685, Broadcom
Kona and Atmel HLCDC)"

This commit adds support for NXP LPC18xx PWM/SCT.
NXP LPC SoCs family, which includes LPC18xx/LPC43xx, provides a State
Configurable Timer (SCT) which can be configured as a Pulse Width
Modulator. Other SoCs in that family may share the same hardware.
The PWM supports a total of 16 channels, but only 15 can be simultaneously
requested. There's only one period, global to all the channels, thus PWM
driver will refuse setting different values to it, unless there's only one
channel requested.

Previously, period_ns and duty_ns were only used to determine the
ratio of ON and OFF time, the default frequency of 200 Hz was never
changed.
The PCA9685 however is capable of changing the PWM output frequency,
which is expected when changing the period.
This patch configures the prescaler accordingly, using the formula
and notes provided in the PCA9685 datasheet.
Bounds checking for the minimum and maximum frequencies, last updated
in revision v.4 of said datasheet, is also added.
The prescaler is only touched if the period changed, because we have to
put the chip into sleep mode to unlock the prescale register.
If it is changed, the PWM output frequency changes for all outputs,
because there is one prescaler per chip. This is documented in the
PCA9685 datasheet and in the comments.
If the duty cycle is not changed at the same time as the period, then
we restart the PWM output using the duty cycle to period ratio from
before the period change.
When using LEDs for example, previously set brightness levels stay the
same when the frequency changes.

Problems:
- When duty_ns == period_ns, the full OFF bit was not cleared and the
PWM output of the PCA9685 stayed off.
- When duty_ns == period_ns and the catch-all channel was used, the
ALL_LED_OFF_L register was not cleared.
- The full ON bit was not cleared when setting the OFF time, therefore
the exact OFF time was ignored when setting a duty_ns < period_ns
Solution: Clear both OFF registers when setting full ON and clear the
full ON bit when changing the OFF registers.

Update the driver so that settings are applied in accordance with the
most recent version of the hardware spec. The revised sequence clears
the trigger bit, waits 400ns, writes settings, sets the trigger bit,
and waits another 400ns. This corrects an issue where occasionally a
requested change was not properly reflected in the PWM output.

The current code will check for polarity in a boolean way. While it is
correct that polarity is either normal or inversed, make it more obvious
that it's an enumeration by using a switch statement and explicit
matches on the enumeration values.

Followup to the UFS series - with the way we clear the new blocks (via
buffer cache, possibly on more than a page worth of file) we really
should not insert a reference to new block into inode block tree until
after we'd cleared it.

Balloon device is frequently used as a mean of cooperative memory control
in between guest and host to manage memory overcommitment. This is the
typical case for any hosting workload when KVM guest is provided for
end-user.
Though there is a problem in this setup. The end-user and hosting provider
have signed SLA agreement in which some amount of memory is guaranted for
the guest. The good thing is that this memory will be given to the guest
when the guest will really need it (f.e. with OOM in guest and with
VIRTIO_BALLOON_F_DEFLATE_ON_OOM configuration flag set). The bad thing
is that end-user does not know this.
Balloon by default reduce the amount of memory exposed to the end-user
each time when the page is stolen from guest or returned back by using
adjust_managed_page_count and thus /proc/meminfo shows reduced amount
of memory.
Fortunately the solution is simple, we should just avoid to call
adjust_managed_page_count with VIRTIO_BALLOON_F_DEFLATE_ON_OOM set.

arrays of pfns and now it takes pointer to struct virtio_ballon.
This change is necessary to conditionally call adjust_managed_page_count

VIRTIO_BLK_F_CONFIG_WCE is important in order to achieve good performance
(up to 2x, though more realistically +30-40%) in latency-bound workloads.
However, it was removed by mistake together with VIRTIO_BLK_F_FLUSH.
It will be restored in the next revision of the virtio 1.0 standard, so
do the same in Linux.

Change metag Transparent Huge Pages (THP) support from .. to TODO. Meta2
has variable sized pages, between 4KB and 4MB, specified at the 1st
level page table level, and already supports hugetlbfs, so supporting
THP is theoretically possible too.

Migrate nios2 driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now.
This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED.
