Andreas Herrmann da7d3abe1c Revert "cpufreq: pcc-cpufreq: update default value of cpuinfo_transition_latency"
This reverts commit 790d849bf8.

Using a v4.7-rc7 kernel on a HP ProLiant triggered following messages

 pcc-cpufreq: (v1.10.00) driver loaded with frequency limits: 1200 MHz, 2800 MHz
 cpufreq: ondemand governor failed, too long transition latency of HW, fallback to performance governor

The last line was shown for each CPU in the system.
Testing v4.5 (where commit 790d849b was integrated) triggered
similar messages. Same behaviour on a 2nd HP Proliant system.

So commit 790d849bf (cpufreq: pcc-cpufreq: update default value of
cpuinfo_transition_latency) causes the system to use performance
governor which, I guess, was not the intention of the patch.

Enabling debug output in pcc-cpufreq provides following verbose output:

 pcc-cpufreq: (v1.10.00) driver loaded with frequency limits: 1200 MHz, 2800 MHz
 pcc_get_offset: for CPU 0: pcc_cpu_data input_offset: 0x44, pcc_cpu_data output_offset: 0x48
 init: policy->max is 2800000, policy->min is 1200000
 get: get_freq for CPU 0
 get: SUCCESS: (virtual) output_offset for cpu 0 is 0xffffc9000d7c0048, contains a value of: 0xff06. Speed is: 168000 MHz
 cpufreq: ondemand governor failed, too long transition latency of HW, fallback to performance governor
 target: CPU 0 should go to target freq: 2800000 (virtual) input_offset is 0xffffc9000d7c0044
 target: was SUCCESSFUL for cpu 0

I am asking to revert 790d849bf to re-enable usage of ondemand
governor with pcc-cpufreq.

Eric Auger 995a0ee980 KVM: arm/arm64: Enable MSI routing
Up to now, only irqchip routing entries could be set. This patch
adds the capability to insert MSI routing entries.

For ARM64, let's also increase KVM_MAX_IRQ_ROUTES to 4096: this
include SPI irqchip routes plus MSI routes. In the future this
might be extended.

Eric Auger 180ae7b118 KVM: arm/arm64: Enable irqchip routing
This patch adds compilation and link against irqchip.

Main motivation behind using irqchip code is to enable MSI
routing code. In the future irqchip routing may also be useful
when targeting multiple irqchips.

Routing standard callbacks now are implemented in vgic-irqfd:
- kvm_set_routing_entry
- kvm_set_irq
- kvm_set_msi

They only are supported with new_vgic code.

Both HAVE_KVM_IRQCHIP and HAVE_KVM_IRQ_ROUTING are defined.
KVM_CAP_IRQ_ROUTING is advertised and KVM_SET_GSI_ROUTING is allowed.

So from now on IRQCHIP routing is enabled and a routing table entry
must exist for irqfd injection to succeed for a given SPI. This patch
builds a default flat irqchip routing table (gsi=irqchip.pin) covering
all the VGIC SPI indexes. This routing table is overwritten by the
first first user-space call to KVM_SET_GSI_ROUTING ioctl.

MSI routing setup is not yet allowed.

On ARM, the MSI msg (address and data) comes along with
out-of-band device ID information. The device ID encodes the
device that writes the MSI msg. Let's convey the device id in
kvm_irq_routing_msi and use KVM_MSI_VALID_DEVID flag value in
kvm_irq_routing_entry to indicate the msi devid is populated.

Luis R. Rodriguez a9e064c004 coccicheck: add support for requring a coccinelle version
Enable Coccinelle SmPL patches to require a specific version of
Coccinelle. In the event that the version does not match we just
inform the user, if the user asked to go through all SmPL patches
we just inform them of the need for a new version of coccinelle for
the SmPL patch and continue on with the rest.

This uses the simple kernel scripts/ld-version.sh to create a weight
on the version provided by spatch. The -dirty attribute is ignored if
supplied, the benefit of scripts/ld-version.sh is it has a long history
and well tested.

While at it, document the // Options stuff as well.

v4: Document // Options and // Requires as well on

Luis R. Rodriguez dd951fc1b6 scripts: add Linux .cocciconfig for coccinelle
Coccinelle supports reading .cocciconfig, the order of precedence for
variables for .cocciconfig is as follows:

 o Your current user's home directory is processed first
 o Your directory from which spatch is called is processed next
 o The directory provided with the --dir option is processed last, if used

Since coccicheck runs through make, it naturally runs from the kernel
proper dir, as such the second rule above would be implied for picking up a
.cocciconfig when using 'make coccicheck'.

'make coccicheck' also supports using M= targets.If you do not supply
any M= target, it is assumed you want to target the entire kernel.
The kernel coccicheck script has:

    if [ "$KBUILD_EXTMOD" = "" ] ; then
        OPTIONS="--dir $srctree $COCCIINCLUDE"
    else
        OPTIONS="--dir $KBUILD_EXTMOD $COCCIINCLUDE"
    fi

KBUILD_EXTMOD is set when an explicit target with M= is used. For both cases
the spatch --dir argument is used, as such third rule applies when
whether M= is used or not, and when M= is used the target directory can
have its own .cocciconfig file. When M= is not passed as an argument to
coccicheck the target directory is the same as the directory from where
spatch was called.

If not using the kernel's coccicheck target, keep the above precedence order
logic of .cocciconfig reading. If using the kernel's coccicheck target,
override any of the kernel's .coccicheck's settings using SPFLAGS.

We help Coccinelle when used against Linux with a set of sensible defaults
options for Linux with our own Linux .cocciconfig. This hints to coccinelle
git can be used for 'git grep' queries over coccigrep. A timeout of 200
seconds should suffice for now.

The options picked up by coccinelle when reading a .cocciconfig do not appear
as arguments to spatch processes running on your system, to confirm what
options will be used by Coccinelle run:

  spatch --print-options-only

You can override with your own preferred index option by using SPFLAGS.
Coccinelle supports both glimpse and idutils. Glimpse had historically
provided the best performance, however recent benchmarks reveal idutils
is performing just as well. Due to some recent fixes however you however
will need at least coccinelle >= 1.0.6 if using idutils.

Coccinelle carries a script scripts/idutils_index.sh which creates the
idutils database with as follows:

    mkid -i C --output .id-utils.index

If using just "--use-idutils" coccinelle expects your idutils database to be
on the top level of the kernel as a file named ".id-utils.index". If you do
not use this you can symlink your database file to it, or you can specify the
database file following the "--use-idutils" argument. Examples:

    make SPFLAGS=--use-idutils coccicheck

This assumes you have $srctree/.id-utils.index, where $srctree is
the top level of the kernel.

    make SPFLAGS="--use-idutils /full-path/to/ID" coccicheck

Here you specify the full path of the idutils ID database. Using
.cocciconfig is possible, however given the order of precedence followed
by Coccinelle, and since the kernel now carries its own .cocciconfig,
you will need to use SPFLAGS to use idutils if desired.

v4:

o Recommend upgrade for using idutils with coccinelle due to some
  recent fixes.

o Refer to using --print-options-only for testing what options are
  picked up by .cocciconfig reading.

o Expand commit log considerably explaining *why* .cocconfig from
  two precedence rules are used when using coccicheck, and how to
  properly override these if needed.

o Expand Documentation/coccinelle.txt

v3: Expand commit log a bit more

Luis R. Rodriguez c930a1b23b coccicheck: enable parmap support
Coccinelle has had parmap support since 1.0.2, this means
it supports --jobs, enabling built-in multithreaded functionality,
instead of needing one to script it out. Just look for --jobs
in the help output to determine if this is supported and use it
only if your number of processors detected is > 1.

If parmap is enabled also enable the load balancing to be dynamic, so
that if a thread finishes early we keep feeding it.

stderr is currently sent to /dev/null, addressing a way to capture
that will be addressed next.

If --jobs is not supported we fallback to the old mechanism.
We expect to deprecate the old mechanism as soon as we can get
confirmation all users are ready.

While at it propagate back into the shell script any coccinelle error
code. When used in serialized mode where all cocci files are run this
also stops processing if an error has occured. This lets us handle some
errors in coccinelle cocci files and if they bail out we should inspect
the errors. This will be more useful later to help annotate coccinelle
version dependency requirements. This will let you run only SmPL files
that your system supports.

Extend Documentation/coccinelle.txt as well.

As a small example, prior to this change, on an 8-core system:

Before:

$ export COCCI=scripts/coccinelle/free/kfree.cocci
$ time make coccicheck MODE=report
...

real    29m14.912s
user    103m1.796s
sys     0m4.464s

After:

real    16m22.435s
user    128m30.060s
sys     0m2.712s

v4:

o expand Documentation/coccinelle.txt to reflect parmap support info
o update commit log to reflect what we actually do now with stderr
o split out DEBUG_FILE use into another patch
o detect number of CPUs and if its 1 then skip parmap support,
  note that if you still support parmap, but have 1 CPU you will
  also go through the new branches, so the old complex multithreaded process
  is skipped as well.

v3:

o move USE_JOBS to avoid being overriden

v2:

o redirect coccinelle stderr to /dev/null by default and
  only if DEBUG_FILE is used do we pass it to a file
o fix typo of paramap/parmap

Set the affinity_mask in the PCI device before allocating vectors so that

__pci_enable_msix_range() helpers are factored out of their not prefixed
variants which assigning the new IRQ affinity mask in the PCI device so
that the low-level interrupt code can perform the interrupt affinity
assignment and do node-local allocations.

A new PCI_IRQ_NOAFFINITY flag is added to pci_alloc_irq_vectors() so that
this function can also be used by drivers that don't wish to use the
automatic affinity assignment.

at least some of the status information can be provided by the watchdog
core.

Provide the available status bits directly from the watchdog driver core.
Call the driver status function if it exists to get the boot status, but
always provide WDIOF_MAGICCLOSE and WDIOF_KEEPALIVEPING internally.

Andre Przywara 1085fdc68c KVM: arm64: vgic-its: Introduce new KVM ITS device
Introduce a new KVM device that represents an ARM Interrupt Translation
Service (ITS) controller. Since there can be multiple of this per guest,
we can't piggy back on the existing GICv3 distributor device, but create
a new type of KVM device.
On the KVM_CREATE_DEVICE ioctl we allocate and initialize the ITS data
structure and store the pointer in the kvm_device data.
Upon an explicit init ioctl from userland (after having setup the MMIO
address) we register the handlers with the kvm_io_bus framework.
Any reference to an ITS thus has to go via this interface.

Andre Przywara 2b8ddd9337 KVM: Extend struct kvm_msi to hold a 32-bit device ID
The ARM GICv3 ITS MSI controller requires a device ID to be able to
assign the proper interrupt vector. On real hardware, this ID is
sampled from the bus. To be able to emulate an ITS controller, extend
the KVM MSI interface to let userspace provide such a device ID. For
PCI devices, the device ID is simply the 16-bit bus-device-function
triplet, which should be easily available to the userland tool.

Also there is a new KVM capability which advertises whether the
current VM requires a device ID to be set along with the MSI data.
This flag is still reported as not available everywhere, later we will
enable it when ITS emulation is used.

There were several files under Documentation/video4linux/bttv.

Instead of simply copying them to the rst folder, I opted to
merge into a single document and adjust the headers to
adjust the section levels and fix the cards tables.

There are two exceptions on the merge:

- The Tuners were renamed as a separate document, as they
  describe a separate driver;

- I removed the PROBLEMS section. It describes problems with
  the very first generation of 3D boards (Mistique/S3).
  It sounds very unlikely that someone would still need to
  install a bttv board on such hardware. Also, it is not
  very well written, IMHO.

Commit 0dfd582e02 ("watchdog: qcom: use timer devicetree
binding") moved to use the watchdog as a subset timer
register block. Some devices have the watchdog completely
standalone with slightly different register offsets as
well so let's account for the differences here.

The existing "kpss-standalone" compatible string doesn't
make it entirely clear exactly what the device is so
rename to "kpss-wdt" to reflect watchdog timer
functionality. Also update ipq4019 DTS with an SoC
specific compatible.

Mauro Carvalho Chehab 89cb3ddbe7 [media] doc-rst: Fix conversion for v4l2 core functions
The conversion from DocBook lead into some conversion issues,
basically due to the lack of proper support at kernel-doc.

So, address them:

- Now, the C files with the exported symbols also need to be
  added. So, all headers need to be included twice: one to
  get the structs/enums/.. and another one for the functions;

- Notes should use the ReST tag, as kernel-doc doesn't
  recognizes it anymore;

- Identation needs to be fixed, as ReST uses it to identify
  when a format "tag" ends.

- kernel-doc doesn't escape things like *pointer, so we
  need to manually add a escape char before it.

- On some cases, kernel-doc conversion requires violating
  the 80-cols, as otherwise it won't properly parse the
  source code.

drm/tegra: Changes for v4.8-rc1

This set of changes contains a bunch of cleanups to the host1x driver as
well as the addition of a pin controller for DPAUX, which is required by
boards to configure the DPAUX pads in AUX mode (for DisplayPort) or I2C
mode (for HDMI and DDC).

Included is also a bit of rework of the SOR driver in preparation to add
DisplayPort support as well as some refactoring and cleanup.

Finally, all output drivers are converted to runtime PM, which greatly
simplifies the handling of clocks and resets.

Mauro Carvalho Chehab 520a247760 doc-rst: Fix compilation of the pdf docbook
The rst2pdf tool is a very broken toolchain, with is not capable
of parsing complex documents. As such, it doesn't build the
media book, failing with:

	[ERROR] pdfbuilder.py:130 too many values to unpack

(using rst2pdf version 0.93.dev-r0 and Sphinx version 1.4.5)

So, make it build only the books we know that are safe to build.

Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

--

Btw, with the standard Sphinx version shipped on Fedora 24 (Sphinx
1.3.1), rst2pdf doesn't build even the simple kernel-documentation,
failing with this error:
    writing Kernel... [ERROR] pdfbuilder.py:130 list index out of range

This is a known bug:
    https://github.com/sphinx-doc/sphinx/issues/1844

So, maybe we should just disable pdf generation from RST for good,
as I suspect that maintaining it with a broken toolchain will be a
big headache.

The samsung,exynos5433-spi has some peculiarities that bring the
need of creating a new compatible in the binding.

One of those is the 3-clocks controller management where the spi
is fed with three clocks: "spi", "busclkN" and "ioclk".

By adding the exynos5433-spi, we deprecate the exynos7 compatible
and discourage its use.

Thierry Reding 5d2304c1de dt-bindings: display: tegra: Add source clock for SOR
The SOR clock can have various sources, with the most commonly used
being the sor_safe, pll_d2_out0, pll_dp and sor_brick clocks. These
are configured using a three level mux, of which the first 2 levels
can be treated as one. The direct parents of the SOR clock are the
sor_safe, sor_brick and sor_src clocks, whereas the pll_d2_out0 and
pll_dp clocks can be selected as parents of the sor_src clock via a
second mux.

Previous generations of Tegra have only supported eDP and LVDS with
the SOR, where LVDS was never used on publicly available hardware.
Clocking for this only ever required the first level mux (to select
between sor_safe and sor_brick).

Tegra210 has a new revision of the SOR that supports HDMI and hence
needs to support the second level mux to allow selecting pll_d2_out0
as the SOR clock's parent. This second mux is knows as sor_src, and
operating system software needs a reference to it in order to select
the proper parent.

Radim Krčmář c519265f2a KVM: x86: add a flag to disable KVM x2apic broadcast quirk
Add KVM_X2APIC_API_DISABLE_BROADCAST_QUIRK as a feature flag to
KVM_CAP_X2APIC_API.

The quirk made KVM interpret 0xff as a broadcast even in x2APIC mode.
The enableable capability is needed in order to support standard x2APIC and
remain backward compatible.

Radim Krčmář 3713131345 KVM: x86: add KVM_CAP_X2APIC_API
KVM_CAP_X2APIC_API is a capability for features related to x2APIC
enablement.  KVM_X2APIC_API_32BIT_FORMAT feature can be enabled to
extend APIC ID in get/set ioctl and MSI addresses to 32 bits.
Both are needed to support x2APIC.

The feature has to be enableable and disabled by default, because
get/set ioctl shifted and truncated APIC ID to 8 bits by using a
non-standard protocol inspired by xAPIC and the change is not
backward-compatible.

Changes to MSI addresses follow the format used by interrupt remapping
unit.  The upper address word, that used to be 0, contains upper 24 bits
of the LAPIC address in its upper 24 bits.  Lower 8 bits are reserved as
0.  Using the upper address word is not backward-compatible either as we
didn't check that userspace zeroed the word.  Reserved bits are still
not explicitly checked, but non-zero data will affect LAPIC addresses,
which will cause a bug.

Greg Kroah-Hartman 6c71ee3b61 Third set of IIO new device support, features and cleanups for the 4.8 cycle.
New core features
 - Selection of the clock source for IIO timestamps.  This is done per device
   as it makes little sense to have events in one timebase and data timestamped
   on another.  Biggest reason for this is that we currently use a clock
   source which is non monotonic which can result in 'interesting' data sets.
   (Includes export for get_monotonic_corse64 which Thomas Gleixner didn't mind
    in an earlier version.)
 - MAINTAINERS add the git tree to the list for IIO.
 
 New device support + a kind of indirect staging graduation.
 * Broadcom iproc-static-adc
   - new driver
 * mcp4531
   - support for MCP454x, MCP456x, MCP464x and MCP466x potentiometers
 * mpu6050
   - support the IC20608 6 axis motion tracking device
 * st-sensors
   - support the lis3l02dq + drop the lis3l02dq driver from staging.
   The general purpose driver is missing event support, but good to get
   rid of this driver which was rather long in the tooth.
 
 New driver features
 * ak8975
   - Add vid regulator support and refactor handling in general.
   - Allow a delay after enabling regulators.
   - Runtime and system PM.
 * bmg160
   - filter frequency control support.
 * bmp280
   - SPI device support.
   - EOC interrupt support for the BMP085
   - power management support.
   - supply regulator support.
   - reset gpio support
   - dt bindings for reset gpio and regulators.
   - of table to support device tree registration
 * max1363
   - Device tree bindings.
 * mcp4531
   - Device tree bindings.
 * st-pressure
   - temperature channels as part of triggered buffer (previously not due
   probably to alignment issues - see below).
   - lps22hb open drain interrupt support.
   - lps22hb temperature channel support
 
 Cleanups and reworkings.
 * numerous ADC drivers
   - ensure the iio_dev->dev.of_node is set to the parent dev.of_node so
   as to allow client bindings to find the device.
 * ak8975
   - Fix incorrect handling of missing regulator
   - make sure power is down and remove.
 * bmp280
   - read the calibration data only once as it doesn't change.
 * isl29125
   - Use a few macros to make code a touch more readable.
 * mma8452
   - fix a memory leak on error.
   - drop an unecessary bit of return value handling.
 * potentiometer kconfig
   - typo fix.
 * st-pressure
   - drop some uninformative default assignments of elements of the channel
   array structure (aids readability).
 * st-sensors
   - Harden interrupt handling considerably.  These are actually all using
   level interrupts, but at least two known boards have them wired to
   edge only interrupt chips.  Hence a slightly interesting bit of handling
   is needed in which we first allow for the easy option (level triggered) and
   secondly check the status registers before reenabling edge interrupts and
   fall back to a tight loop in the thread until we successfully clear the
   interrupt.  No harm is done if we never succeed in doing so.  It's an odd
   patch that has been through a lot of revisions to reach a consensus on how
   to handle what is basically broken hardware (which the previous defaults
   allowed to kind of work).
   - Fix alignment to defined storagebytes boundaries.
   - Ensure alignment of power of 2 byte boundaries.  This has always in theory
   been part of the ABI of IIO, but we missed a few that snuck in that need
   fixing.  The effect was minor as they were only followed by timestamp
   channels which were correctly aligned,
   - Add some docs to explain the gain calculations.

Steve Capper f8d9f92452 arm64: cpuinfo: Expose MIDR_EL1 and REVIDR_EL1 to sysfs
It can be useful for JIT software to be aware of MIDR_EL1 and
REVIDR_EL1 to ascertain the presence of any core errata that could
affect code generation.

This patch exposes these registers through sysfs:

/sys/devices/system/cpu/cpu$ID/regs/identification/midr_el1
/sys/devices/system/cpu/cpu$ID/regs/identification/revidr_el1

where $ID is the cpu number. For big.LITTLE systems, one can have a
mixture of cores (e.g. Cortex A53 and Cortex A57), thus all CPUs need
to be enumerated.

If the kernel does not have valid information to populate these entries
with, an empty string is returned to userspace.

Mauro Carvalho Chehab e70fb059a4 [media] doc-rst: fix a missing reference for V4L2_BUF_FLAG_LAST
Fix it by adding a header to the flat-table to match to
the list of define symbols.

As a side-effect, it also removes some exceptions from
videodev2.h.rst.
