Revert commit 033291eccbdb ("vfio: Include No-IOMMU mode") due to lack
of a user. This was originally intended to fill a need for the DPDK
driver, but uptake has been slow so rather than support an unproven
kernel interface revert it and revisit when userspace catches up.

There is really no way to safely give a user full access to a DMA
capable device without an IOMMU to protect the host system. There is
also no way to provide DMA translation, for use cases such as device
assignment to virtual machines. However, there are still those users
that want userspace drivers even under those conditions. The UIO
driver exists for this use case, but does not provide the degree of
device access and programming that VFIO has. In an effort to avoid
code duplication, this introduces a No-IOMMU mode for VFIO.
This mode requires building VFIO with CONFIG_VFIO_NOIOMMU and enabling
the "enable_unsafe_noiommu_mode" option on the vfio driver. This
should make it very clear that this mode is not safe. Additionally,
CAP_SYS_RAWIO privileges are necessary to work with groups and
containers using this mode. Groups making use of this support are
named /dev/vfio/noiommu-$GROUP and can only make use of the special
VFIO_NOIOMMU_IOMMU for the container. Use of this mode, specifically
binding a device without a native IOMMU group to a VFIO bus driver
will taint the kernel and should therefore not be considered
supported. This patch includes no-iommu support for the vfio-pci bus
driver only.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Olof Johansson:
"As we've enabled multiplatform kernels on ARM, and greatly done away
with the contents under arch/arm/mach-*, there's still need for
SoC-related drivers to go somewhere.
Many of them go in through other driver trees, but we still have
drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
that might be shared between ARM and ARM64 (or just in general makes
sense to not have under the architecture directory).
This branch contains mostly such code:
- Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to
communicate with power management blocks on these SoCs for use by
clock, regulator and bus frequency drivers.
- Allwinner Reduced Serial Bus driver, again used to communicate with
PMICs.
- Drivers for ARM's SCPI (System Control Processor). Not to be
confused with PSCI (Power State Coordination Interface). SCPI is
used to communicate with the assistant embedded cores doing power
management, and we have yet to see how many of them will implement
this for their hardware vs abstracting in other ways (or not at all
like in the past).
- To make confusion between SCPI and PSCI more likely, this release
also includes an update of PSCI to interface version 1.0.
- Rockchip support for power domains.
- A driver to talk to the firmware on Raspberry Pi"

PSCI v1.0 introduces a new API called PSCI_SYSTEM_SUSPEND. This API
provides the mechanism by which the calling OS can request entry into
the deepest possible system sleep state.
It meets all the necessary preconditions for entering suspend to RAM
state in Linux. This patch adds support for PSCI_SYSTEM_SUSPEND in psci
firmware and registers a psci system suspend operation to implement the
suspend-to-RAM(s2r) in a generic way on all the platforms implementing
PSCI.

PSCI v1.0 augmented the power_state parameter format specification
(extended stateid) and introduced a way to probe it through the
PSCI_FEATURES interface.
This patch implements code that detects the power_state format at
run-time through the PSCI_FEATURES interface, so that the power_state
argument can be properly detected and validated in the kernel according
to the information provided through firmware.

PSCI 1.0 introduces the INVALID_ADDRESS return value for functions
that take an address as input parameter (eg CPU_SUSPEND).
This patch adds INVALID_ADDRESS return value to kernel code and
updates the PSCI to linux error conversion to take it into account.
The kernel error value associated to INVALID_ADDRESS is set to
the error returned when the PSCI error code is INVALID_PARAMETERS
to comply with current call sites expected return value, given
that the kernel at present has no use for the additional error
information reported.

Pull drm updates from Dave Airlie:
"I Was Almost Tempted To Capitalise Every Word, but then I decided I
couldn't read it myself!
I've also got one pull request for the sti driver outstanding. It
relied on a commit in Greg's tree and I didn't find out in time, that
commit is in your tree now so I might send that along once this is
merged.
I also had the accidental misfortune to have access to a Skylake on my
desk for a few days, and I've had to encourage Intel to try harder,
which seems to be happening now.
Here is the main drm-next pull request for 4.4.
Highlights:
New driver:
vc4 driver for the Rasberry Pi VPU.
(From Eric Anholt at Broadcom.)
Core:
Atomic fbdev support
Atomic helpers for runtime pm
dp/aux i2c STATUS_UPDATE handling
struct_mutex usage cleanups.
Generic of probing support.
Documentation:
Kerneldoc for VGA switcheroo code.
Rename to gpu instead of drm to reflect scope.
i915:
Skylake GuC firmware fixes
HPD A support
VBT backlight fallbacks
Fastboot by default for some systems

Similar to the 'limit' filter, we can enhance the 'usage' filter to
accept a range. The change is backward compatible, the range is applied
only in connection with the BTRFS_BALANCE_ARGS_USAGE_RANGE flag.
We don't have a usecase yet, the current syntax has been sufficient. The
enhancement should provide parity with other range-like filters.

The 'limit' filter is underdesigned, it should have been a range for
[min,max], with some relaxed semantics when one of the bounds is
missing. Besides that, using a full u64 for a single value is a waste of
bytes.
Let's fix both by extending the use of the u64 bytes for the [min,max]
range. This can be done in a backward compatible way, the range will be
interpreted only if the appropriate flag is set
(BTRFS_BALANCE_ARGS_LIMIT_RANGE).

Debugging input devices, specifically laptop touchpads, can be tricky
without having the physical device handy. Here we try to remedy that
with userio. This module allows an application to connect to a character
device provided by the kernel, and emulate any serio device. In
combination with userspace programs that can record PS/2 devices and
replay them through the /dev/userio device, this allows developers to
debug driver issues on the PS/2 level with devices simply by requesting
a recording from the user experiencing the issue without having to have
the physical hardware in front of them.

Hardware manufacturers group keys in the weirdest way possible. This may
cause a power-key to be grouped together with normal keyboard keys and
thus be reported on the same kernel interface.
However, user-space is often only interested in specific sets of events.
For instance, daemons dealing with system-reboot (like systemd-logind)
listen for KEY_POWER, but are not interested in any main keyboard keys.
Usually, power keys are reported via separate interfaces, however,
some i8042 boards report it in the AT matrix. To avoid waking up those
system daemons on each key-press, we had two ideas:
- split off KEY_POWER into a separate interface unconditionally
- allow filtering a specific set of events on evdev FDs
Splitting of KEY_POWER is a rather weird way to deal with this and may
break backwards-compatibility. It is also specific to KEY_POWER and might
be required for other stuff, too. Moreover, we might end up with a huge
set of input-devices just to have them properly split.
Hence, this patchset implements the second idea: An event-mask to specify
which events you're interested in. Two ioctls allow setting this mask for
each event-type. If not set, all events are reported. The type==0 entry is
used same as in EVIOCGBIT to set the actual EV_* mask of filtered events.
This way, you have a two-level filter.
We are heavily forward-compatible to new event-types and event-codes. So
new user-space will be able to run on an old kernel which doesn't know the
given event-codes or event-types.

There is an undocumented upper bound for the total number of ff effects:
FF_GAIN (= 96).
This can be found as follows:
- user: write(EV_FF, effect_id, iterations)
calls kernel: ff->playback(effect_id, ...): starts effect "effect_id"
- user: write(EV_FF, FF_GAIN, gain)
calls kernel: ff->set_gain(gain, ...): sets gain
A collision occurs when effect_id equals FF_GAIN.
According to input_ff_event(),
FF_GAIN is the smallest value where a collision occurs.
Therefore the greatest safe value for effect_id is FF_GAIN - 1,
and thus the total number of effects should never exceed FF_GAIN.
Define FF_MAX_EFFECTS as FF_GAIN and check on this limit in ff-core.

Add input-event-codes header file and move all type and axis defines
there.
The purpose of this new header file is to have a single canonical source
for event-codes which can be used outside of C-code too. One example of
such usage is the use of event-codes in devicetree source files.

Pull MTD updates from Brian Norris:
"Core:
- WARN (in some cases) when a struct mtd_info is registered multiple
times; in the past this was "supported", but it's still error prone
for future development. There's only one ugly case of this left in
the tree (that we're aware of) and the owners are aware of the
problems there.
- fix potential deadlock in the blkdev removal path NOTE: the
(potential) deadlock was introduced in a for-stable patch. This
one is also marked for -stable.
- ioctl(BLKPG) compat_ioctl support; resolves issues with 32-bit user
space vs 64-bit kernel space
- Set MTD parent device correctly throughout the tree, so the tree
structure appears correctly in sysfs; many drivers were missing
this (soft) requirement
- Move device tree partitions (ofpart) into a dedicated 'partitions'
subnode; this helps to disambiguate whether a node is a partition
or some other auxiliary data
- Improve error handling for partitioning failures
NAND:
- General: Increase timeout period, for corner-case systems with
less-than-accurate jiffies
- Fix OF-based autoloading of several NAND drivers when built as
modules
- pxa3xx_nand:
- Rework timing configuration to be more dynamic
- Refactor PM support
- brcmnand: prepare for NorthStar 2 support (ARM64, 16-bit NAND
chips)
- sunxi_nand: refactoring and a few bug fixes
- vf610: new NAND driver
- FSMC: add SW BCH support; support common NAND DT bindings
- lpc32xx_slc: refactor and improve timing calculations logic
- denali: support for rev 5.1
SPI NOR:
- Layering improvements
- Added Winbond lock/unlock support
- Added mtd_is_locked() (i.e., ioctl(MEMISLOCKED)) support
- Increase full-chip-erase timeout linearly with flash size
- fsl-quadspi: fix compile for non-ARM architectures
- New flash support"

After a bit of poking around wondering why my 32-bit user-space can't
seem to send a proper ioctl(BLKPG) to an MTD on my 64-bit kernel
(ARM64), I noticed that struct blkpg_ioctl_arg is actually pretty
unsuitable for use in the ioctl() ABI, due to its use of raw pointers,
and its lack of alignment/packing restrictions (32-bit arch'es tend to
pack the 4 fields into 4 32-bit words, whereas 64-bit arch'es would add
padding after the third int, and make this 6 32-bit words).
Anyway, this means BLKPG deserves some special compat_ioctl handling. Do
the conversion in a small shim for MTD.
block/compat_ioctl.c already has compat support for the block subsystem,
but it does so by a re-marshalling data to/from user-space (see
compat_blkpg_ioctl()). Personally, I think this approach is cleaner.
Tested only on MTD, with an ARM32 user space on an ARM64 kernel.

Expand bitmask #defines completely. This puts the shift in the code
instead of in the #define, but it makes it more obvious in the header file
how fields in the register are laid out.
No functional change.

Pull KVM updates from Paolo Bonzini:
"First batch of KVM changes for 4.4.
s390:
A bunch of fixes and optimizations for interrupt and time handling.
PPC:
Mostly bug fixes.
ARM:
No big features, but many small fixes and prerequisites including:
- a number of fixes for the arch-timer
- introducing proper level-triggered semantics for the arch-timers
- a series of patches to synchronously halt a guest (prerequisite
for IRQ forwarding)
- some tracepoint improvements
- a tweak for the EL2 panic handlers
- some more VGIC cleanups getting rid of redundant state
x86:
Quite a few changes:
- support for VT-d posted interrupts (i.e. PCI devices can inject
interrupts directly into vCPUs). This introduces a new
component (in virt/lib/) that connects VFIO and KVM together.
The same infrastructure will be used for ARM interrupt
forwarding as well.
- more Hyper-V features, though the main one Hyper-V synthetic
interrupt controller will have to wait for 4.5. These will let
KVM expose Hyper-V devices.
- nested virtualization now supports VPID (same as PCID but for
vCPUs) which makes it quite a bit faster
- for future hardware that supports NVDIMM, there is support for
clflushopt, clwb, pcommit
- support for "split irqchip", i.e. LAPIC in kernel +
IOAPIC/PIC/PIT in userspace, which reduces the attack surface of
the hypervisor
- obligatory smattering of SMM fixes
- on the guest side, stable scheduler clock support was rewritten
to not require help from the hypervisor"

Adds KVM_EXIT_IOAPIC_EOI which allows the kernel to EOI
level-triggered IOAPIC interrupts.
Uses a per VCPU exit bitmap to decide whether or not the IOAPIC needs
to be informed (which is identical to the EOI_EXIT_BITMAP field used
by modern x86 processors, but can also be used to elide kvm IOAPIC EOI
exits on older processors).
[Note: A prototype using ResampleFDs found that decoupling the EOI
from the VCPU's thread made it possible for the VCPU to not see a
recent EOI after reentering the guest. This does not match real
hardware.]
Compile tested for Intel x86.

Add type field to that struct like it counterpart v4l2_tuner
already has. We need type field to distinguish different tuner
types from each others for transmitter too.

Add new RF tuner gain control named RF Gain. That is aimed for first
amplifier chip right after antenna connector.
There is existing LNA Gain control, which is quite same, but it is
aimed for cases amplifier is integrated to tuner chip. Some designs
have both, as almost all recent tuner silicons has integrated LNA/RF
amplifier in any case.

SDR receiver has ADC (Analog-to-Digital Converter) and SDR transmitter
has DAC (Digital-to-Analog Converter). Originally I though it could
be good idea to have own type for receiver and transmitter, but now I
feel one common type for SDR is enough. So lets rename it.
