The kAPI, v4l-drivers and dvb-drivers never used the
GNU FDL license. The addition of such license header were
just due to copy-and-paste. So, let's fix it.
As the media_kapi were part of device-drivers.tmp, it is
under GPL v2+.
The other two books is an agregation of files without any
license explicitly specified. So, they're all bound to the
Kernel's COPYING license. So, they're GPL v2 only.

This reverts commit 790d849bf811a8ab5d4cd2cce0f6fda92f6aebf2.
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.

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

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

SPFLAGS is set early, it means that any heuristics done on
coccicheck cannot be overridden currently. Move SPFLAGS

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.

Unfortunately warnings generated after parsing in sphinx can end up

outright errors this is not a problem. Trying to convert warnings to

The only way to get useful output out of sphinx to be able to root
cause the error seems to be enabling keep_warnings, which inserts
a System Message into the actual output. Not pretty at all, but I
don't really want to fix up core rst/sphinx code, and this gets the job

Right now there's nothing, and kernel-doc produces a warning because
of that. Remove it until we need it for a clean build.

Up to now, the watchdog status function called a driver function,
which was supposed to return the watchdog status. All but one
driver using the watchdog core did not implement this function,
and the driver implementing it did not implement it correctly
(the function is supposed to return WDIOF_ flags). At the same time,
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.
This patch makes the 'status' sysfs attribute always available.
This attribute is now displayed as hex number with 0x prepended to be
easier to decode.

This is an update to the previous drm bridge pull request. The ADV7511
driver's conversion from slave encoder to bridge meant that its users
(the rcar-du kms driver) should use the bridge interface too. This pull
request now also contains a commit that updates the rcar-du's hdmi encoder
interface from slave encoder to bridge.
The other updates are as before:
- Converts the ADV7511 i2c slave encoder driver to a bridge driver.
Adds support for the ADV7533 bridge chip.
- Add bridge driver for TC358767 (DSI/DPI to eDP) encoder chips.
* 'drm_bridge_for_4.8' of https://github.com/boddob/linux:
drm: rcar-du: Remove i2c slave encoder interface for hdmi encoder
drm/bridge: tc358767: Add DPI to eDP bridge driver
dt-bindings: tc358767: add DT documentation
dt-bindings: drm/bridge: Update bindings for ADV7533
drm/bridge: adv7533: Change number of DSI lanes dynamically
drm/bridge: adv7533: Use internal timing generator
drm/bridge: adv7533: Create a MIPI DSI device
drm/bridge: adv7533: Initial support for ADV7533
drm/bridge: adv7511: Fix mutex deadlock when interrupts are disabled
drm/i2c: adv7511: Move to bridge folder
drm/i2c: adv7511: Convert to drm_bridge
It can be hard for people not familiar with the CoreSight IP blocks
to make sense of the acronyms found in the current bindings. As such
this patch expands each acronym in the hope of providing a better
description of the IP block they represent.
