The documentation currently uses the non-standard vendor prefix stm
and st-micro for STMicroelectronics. The drivers do not specify the
vendor prefixes since the I2C Core strips them away from the DT
provided compatible string. Therefor, changing documentation and
existing device trees does not have any impact on device detection.

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.

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.

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.

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
the affinity can be propagated through the MSI descriptor structures to the
core IRQ code. To facilitate this, new __pci_enable_msi_range() and
__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.

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.

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.

So, address them:

- Notes should use the ReST tag, as kernel-doc doesn't

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

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:

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.
Addition of device tree support for DA9210.

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.

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.

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.

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

* st-sensors
- support the lis3l02dq + drop the lis3l02dq driver from staging.

rid of this driver which was rather long in the tooth.

- Allow a delay after enabling regulators.
- Runtime and system PM.

Cleanups and reworkings.
* numerous ADC drivers
- ensure the iio_dev->dev.of_node is set to the parent dev.of_node so

* 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.

As we're removing it on Kernel 4.8, it doesn't make sense to
apply the original patches, but, as the typos were ported
to ReST, let's fix the issues there.

This reverts commit ffbab694ed.
The timestamp field was split into rx_ts and tx_ts, and the rx/tx_status
fields were moved. Update the doc accordingly.
Also fix a bug that stated that a non-zero tx_status field signaled an

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.

Make it possible to protect all pages holding image data during

catch attempts to write to those pages after image data have been
stored in them).
This adds overhead to image restoration code (it may cause large
page mappings to be split as a result of page flags changes) and
the errors it protects against should never happen in theory, so
the feature is only active after passing hibernate=protect_image
to the command line of the restore kernel.
Also it only is built if CONFIG_DEBUG_RODATA is set.

This patch allows SSDTs to be loaded from EFI variables. It works by
specifying the EFI variable name containing the SSDT to be loaded. All
variables with the same name (regardless of the vendor GUID) will be
loaded.
Note that we can't use acpi_install_table and we must rely on the
dynamic ACPI table loading and bus re-scanning mechanisms. That is
because I2C/SPI controllers are initialized earlier then the EFI
subsystems and all I2C/SPI ACPI devices are enumerated when the
I2C/SPI controllers are initialized.

The DMA buffer importing streaming I/O section mentions the memory type
value that has to be set when calling the VIDIOC_REQBUFS ioctl but this
isn't mentioned in neither the Memory Mapping nor User Pointer sections.
A user can know the values by looking at the examples but it's better
to explicitly mention in the documentation, and also makes all sections
about streaming I/O methods more consistent.

On a big-little system, PMUs can be wired to CPUs using per CPU
interrups (PPI). In this case, it is important to make sure that
the enable/disable do happen on the right set of CPUs.
So instead of relying on the interrupt-affinity property, we can
use the actual percpu affinity that DT exposes as part of the
interrupt specifier. The DT binding is also updated to reflect
the fact that the interrupt-affinity property shouldn't be used
in that case.

Randomizes the virtual address space of kernel memory regions for
x86_64. This first patch adds the infrastructure and does not randomize
any region. The following patches will randomize the physical memory
mapping, vmalloc and vmemmap regions.
This security feature mitigates exploits relying on predictable kernel
addresses. These addresses can be used to disclose the kernel modules
base addresses or corrupt specific structures to elevate privileges
bypassing the current implementation of KASLR. This feature can be
enabled with the CONFIG_RANDOMIZE_MEMORY option.
The order of each memory region is not changed. The feature looks at the
available space for the regions based on different configuration options
and randomizes the base and space between each. The size of the physical
memory mapping is the available physical memory. No performance impact
was detected while testing the feature.
Entropy is generated using the KASLR early boot functions now shared in
the lib directory (originally written by Kees Cook). Randomization is
done on PGD & PUD page table levels to increase possible addresses. The
physical memory mapping code was adapted to support PUD level virtual
addresses. This implementation on the best configuration provides 30,000
possible virtual addresses in average for each memory region. An
additional low memory page is used to ensure each CPU can start with a
PGD aligned virtual address (for realmode).
x86/dump_pagetable was updated to correctly display each region.
Updated documentation on x86_64 memory layout accordingly.

The kernel-include directive is needed to include the auto generated rst
content from a build (pre-) process. E.g. the linux_tv Makefile
generates intermediate reST-files from header files. Since there is a O=
option:
make O=dir [targets] Locate all output files in "dir"
We need to include intermediate reST files from arbitrary (O=/tmp/foo)
locations:
The 'kernel-include' reST-directive is a replacement for the 'include'
directive. The 'kernel-include' directive expand environment variables
in the path name and allows to include files from arbitrary locations.
.. hint::
Including files from arbitrary locations (e.g. from '/etc') is a
security risk for builders. This is why the 'include' directive from
docutils *prohibit* pathnames pointing to locations *above* the
filesystem tree where the reST document with the include directive is
placed.
Substrings of the form $name or ${name} are replaced by the value of
environment variable name. Malformed variable names and references to
non-existing variables are left unchanged.
