mac80211: Parse legacy and HT rate in injected frames
Drivers/devices without their own rate control algorithm can get the
information what rates they should use from either the radiotap header of
injected frames or from the rate control algorithm. But the parsing of the
legacy rate information from the radiotap header was removed in commit

Power management and ACPI updates for v4.5-rc1
- Add a debugfs-based interface for interacting with the ACPICA's
AML debugger introduced in the previous cycle and a new user
space tool for that, fix some bugs related to the AML debugger
and clean up the code in question (Lv Zheng, Dan Carpenter,
Colin Ian King, Markus Elfring).
- Update ACPICA to upstream revision 20151218 including a number
of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng,
Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box,
Rafael Wysocki).
In particular, the previously added erroneous support for the
_SUB object is dropped, the concatenate operator will support
all ACPI objects now, the Debug Object handling is improved,
the SuperName handling of parameters being control methods is
fixed, the ObjectType operator handling is updated to follow
ACPI 5.0A and the handling of CondRefOf and RefOf is updated
accordingly, module-level code will be executed after loading
each ACPI table now (instead of being run once after all tables
containing AML have been loaded), the Operation Region handlers
management is updated to fix some reported problems and a the
ACPICA code in the kernel is more in line with the upstream
now.
- Update the ACPI backlight driver to provide information on
whether or not it will generate key-presses for brightness
change hotkeys and update some platform drivers (dell-wmi,
thinkpad_acpi) to use that information to avoid sending double
key-events to users pace for these, add new ACPI backlight
quirks (Hans de Goede, Aaron Lu, Adrien Schildknecht).
- Improve the ACPI handling of interrupt GPIOs (Christophe Ricard).
- Fix the handling of the list of device IDs of device objects
found in the ACPI namespace and add a helper for checking if
there is a device object for a given device ID (Lukas Wunner).
- Change the logic in the ACPI namespace scanning code to create
struct acpi_device objects for all ACPI device objects found in
the namespace even if _STA fails for them which helps to avoid
device enumeration problems on Microsoft Surface 3 (Aaron Lu).
- Add support for the APM X-Gene ACPI I2C device to the ACPI
driver for AMD SoCs (Loc Ho).
- Fix the long-standing issue with the DMA controller on Intel
SoCs where ACPI tables have no power management support for
the DMA controller itself, but it can be powered off automatically
when the last (other) device on the SoC is powered off via ACPI
and clean up the ACPI driver for Intel SoCs (acpi-lpss) after
previous attempts to fix that problem (Andy Shevchenko).
- Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King,
Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki,
Sinan Kaya).
- Update the device properties framework for better handling of
built-in properties, add support for built-in properties to
the platform bus type, update the MFD subsystem's handling
of device properties and add support for passing default
configuration data as device properties to the intel-lpss MFD
drivers, convert the designware I2C driver to use the unified
device properties API and add a fallback mechanism for using
default built-in properties if the platform firmware fails
to provide the properties as expected by drivers (Andy Shevchenko,
Mika Westerberg, Heikki Krogerus, Andrew Morton).
- Add new Device Tree bindings to the Operating Performance Points
(OPP) framework and update the exynos4412 DT binding accordingly,
introduce debugfs support for the OPP framework (Viresh Kumar,
Bartlomiej Zolnierkiewicz).
- Migrate the mt8173 cpufreq driver to the new OPP bindings
(Pi-Cheng Chen).
- Update the cpufreq core to make the handling of governors
more efficient, especially on systems where policy objects
are shared between multiple CPUs (Viresh Kumar, Rafael Wysocki).
- Fix cpufreq governor handling on configurations with
CONFIG_HZ_PERIODIC set (Chen Yu).
- Clean up the cpufreq core code related to the boost sysfs knob
support and update the ACPI cpufreq driver accordingly (Rafael
Wysocki).
- Add a new cpufreq driver for ST platforms and corresponding
Device Tree bindings (Lee Jones).
- Update the intel_pstate driver to allow the P-state selection
algorithm used by it to depend on the CPU ID of the processor it
is running on, make it use a special P-state selection algorithm
(with an IO wait time compensation tweak) on Atom CPUs based on
the Airmont and Silvermont cores so as to reduce their energy
consumption and improve intel_pstate documentation (Philippe
Longepe, Srinivas Pandruvada).
- Update the cpufreq-dt driver to support registering cooling
devices that use the (P * V^2 * f) dynamic power draw formula
where V is the voltage, f is the frequency and P is a constant
coefficient provided by Device Tree and update the arm_big_little
cpufreq driver to use that support (Punit Agrawal).
- Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq,
blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia,
Jacob Tanenbaum, Markus Elfring).
- cpuidle core tweaks related to polling and measured_us
calculation (Rik van Riel).
- Removal of modularity from a few cpuidle drivers (clps711x,
ux500, exynos) that cannot be built as modules in practice
(Paul Gortmaker).
- PM core update to prevent devices from being probed during
system suspend/resume which is generally problematic and may
lead to inconsistent behavior (Grygorii Strashko).
- Assorted updates of the PM core and related code (Julia Lawall,
Manuel Pégourié-Gonnard, Maruthi Bayyavarapu, Rafael Wysocki,
Ulf Hansson).
- PNP bus type updates (Christophe Le Roy, Heiner Kallweit).
- PCI PM code cleanups (Jarkko Nikula, Julia Lawall).
- cpupower tool updates (Jacob Tanenbaum, Thomas Renninger).

Pull oower management and ACPI updates from Rafael Wysocki:
"As far as the number of commits goes, ACPICA takes the lead this time,
followed by cpufreq and the device properties framework changes.
The most significant new feature is the debugfs-based interface to the
ACPICA's AML debugger added in the previous cycle and a new user space
tool for accessing it.
On the cpufreq front, the core is updated to handle governors more
efficiently, particularly on systems where a single cpufreq policy
object is shared between multiple CPUs, and there are quite a few
changes in drivers (intel_pstate, cpufreq-dt etc).
The device properties framework is updated to handle built-in (ie
included in the kernel itself) device properties better, among other
things by adding a fallback mechanism that will allow drivers to
provide default properties to be used in case the plaform firmware
doesn't provide the properties expected by them.
The Operating Performance Points (OPP) framework gets new DT bindings
and debugfs support.
A new cpufreq driver for ST platforms is added and the ACPI driver for
AMD SoCs will now support the APM X-Gene ACPI I2C device.
The rest is mostly fixes and cleanups all over.
Specifics:
- Add a debugfs-based interface for interacting with the ACPICA's AML
debugger introduced in the previous cycle and a new user space tool

Pull cgroup updates from Tejun Heo: - cgroup v2 interface is now official. It's no longer hidden behind a devel flag and can be mounted using the new cgroup2 fs type. Unfortunately, cpu v2 interface hasn't made it yet due to the discussion around in-process hierarchical resource distribution and only memory and io controllers can be used on the v2 interface at the moment. - The existing documentation which has always been a bit of mess is relocated under Documentation/cgroup-v1/. Documentation/cgroup-v2.txt is added as the authoritative documentation for the v2 interface. - Some features are added through for-4.5-ancestor-test branch to enable netfilter xt_cgroup match to use cgroup v2 paths.

Merge branch 'work.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull misc vfs updates from Al Viro:
"All kinds of stuff. That probably should've been 5 or 6 separate
branches, but by the time I'd realized how large and mixed that bag
had become it had been too close to -final to play with rebasing.
Some fs/namei.c cleanups there, memdup_user_nul() introduction and
switching open-coded instances, burying long-dead code, whack-a-mole
of various kinds, several new helpers for ->llseek(), assorted
cleanups and fixes from various people, etc.
One piece probably deserves special mention - Neil's
lookup_one_len_unlocked(). Similar to lookup_one_len(), but gets
called without ->i_mutex and tries to avoid ever taking it. That, of
course, means that it's not useful for any directory modifications,
but things like getting inode attributes in nfds readdirplus are fine
with that. I really should've asked for moratorium on lookup-related
changes this cycle, but since I hadn't done that early enough... I
*am* asking for that for the coming cycle, though - I'm going to try
and get conversion of i_mutex to rwsem with ->lookup() done under lock
taken shared.
There will be a patch closer to the end of the window, along the lines
of the one Linus had posted last May - mechanical conversion of
->i_mutex accesses to inode_lock()/inode_unlock()/inode_trylock()/
inode_is_locked()/inode_lock_nested(). To quote Linus back then:
-----
| This is an automated patch using
|
| sed 's/mutex_lock(&\(.*\)->i_mutex)/inode_lock(\1)/'
| sed 's/mutex_unlock(&\(.*\)->i_mutex)/inode_unlock(\1)/'
| sed 's/mutex_lock_nested(&\(.*\)->i_mutex,[ ]*I_MUTEX_\([A-Z0-9_]*\))/inode_lock_nested(\1, I_MUTEX_\2)/'
| sed 's/mutex_is_locked(&\(.*\)->i_mutex)/inode_is_locked(\1)/'
| sed 's/mutex_trylock(&\(.*\)->i_mutex)/inode_trylock(\1)/'
|
| with a very few manual fixups
-----
I'm going to send that once the ->i_mutex-affecting stuff in -next
gets mostly merged (or when Linus says he's about to stop taking
merges)"

"In the past, I have funnelled perf updates through the respective
architecture trees, but now that the arm/arm64 perf driver has been
largely consolidated under drivers/perf/, it makes more sense to send
a separate pull, particularly as I'm listed as maintainer for all the
files involved. I offered the branch to arm-soc, but Arnd suggested
that I just send it to you directly.
So, here is the arm/arm64 perf queue for 4.5. The main features are
described below, but the most useful change is from Drew, which
advertises our architected event mapping in sysfs so that the perf
tool is a lot more user friendly and no longer requires the use of
magic hex constants for profiling common events.

Merge tag 'pinctrl-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the bulk of pin control patches for the v4.5 series.
Notably I have a patch to driver core from Stephen Boyd in the pull
request, this has been ACKed by Greg so it should be OK. The internal
API needed some tweaking to allow modular Qualcomm pin controllers.
There is a bit of development history in here but it should all add up
nicely and has boiled in linux-next. For example I merged in v4.4-rc5
to get rid of some nasty merge conflicts.
Summary:
- New drivers:
- PXA2xx pin controller support
- Broadcom NSP pin controller support
- New subdrivers:

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar:
"Kernel side changes:
- Intel Knights Landing support. (Harish Chegondi)
- Intel Broadwell-EP uncore PMU support. (Kan Liang)
- Core code improvements. (Peter Zijlstra.)
- Event filter, LBR and PEBS fixes. (Stephane Eranian)

- Add cycles:ppp support for Skylake. (Andi Kleen)
- Various x86 NMI overhead optimizations. (Andi Kleen)
- Intel PT enhancements. (Takao Indoh)
- AMD cache events fix. (Vince Weaver)
Tons of tooling changes:
- Show random perf tool tips in the 'perf report' bottom line
(Namhyung Kim)
- perf report now defaults to --group if the perf.data file has
grouped events, try it with:
# perf record -e '{cycles,instructions}' -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 1.093 MB perf.data (1247 samples) ]

- Introduce the 'perf stat record/report' workflow:
Generate perf.data files from 'perf stat', to tap into the
scripting capabilities perf has instead of defining a 'perf stat'
specific scripting support to calculate event ratios, etc.
Simple example:
$ perf stat record -e cycles usleep 1
Performance counter stats for 'usleep 1':
1,134,996 cycles
0.000670644 seconds time elapsed
$ perf stat report
Performance counter stats for '/home/acme/bin/perf stat record -e cycles usleep 1':
1,134,996 cycles
0.000670644 seconds time elapsed
$
It generates PERF_RECORD_ userspace records to store the details:
$ perf report -D | grep PERF_RECORD
0xf0 [0x28]: PERF_RECORD_THREAD_MAP nr: 1 thread: 27637
0x118 [0x12]: PERF_RECORD_CPU_MAP nr: 1 cpu: 65535
0x12a [0x40]: PERF_RECORD_STAT_CONFIG
0x16a [0x30]: PERF_RECORD_STAT
-1 -1 0x19a [0x40]: PERF_RECORD_MMAP -1/0: [0xffffffff81000000(0x1f000000) @ 0xffffffff81000000]: x [kernel.kallsyms]_text
0x1da [0x18]: PERF_RECORD_STAT_ROUND
[acme@ssdandy linux]$
An effort was made to make perf.data files generated like this to
not generate cryptic messages when processed by older tools.
The 'perf script' bits need rebasing, will go up later.
- Make command line options always available, even when they depend
on some feature being enabled, warning the user about use of such
options (Wang Nan)
- Support hw breakpoint events (mem:0xAddress) in the default output
mode in 'perf script' (Wang Nan)
- Fixes and improvements for supporting annotating ARM binaries,
support ARM call and jump instructions, more work needed to have
arch specific stuff separated into tools/perf/arch/*/annotate/
(Russell King)
- Add initial 'perf config' command, for now just with a --list
command to the contents of the configuration file in use and a
basic man page describing its format, commands for doing edits and
detailed documentation are being reviewed and proof-read. (Taeung
Song)
- Allows BPF scriptlets specify arguments to be fetched using DWARF
info, using a prologue generated at compile/build time (He Kuang,
Wang Nan)
- Allow attaching BPF scriptlets to module symbols (Wang Nan)
- Allow attaching BPF scriptlets to userspace code using uprobe (Wang
Nan)
- BPF programs now can specify 'perf probe' tunables via its section
name, separating key=val values using semicolons (Wang Nan)
Testing some of these new BPF features:
Use case: get callchains when receiving SSL packets, filter then in the
kernel, at arbitrary place.

- Use 'perf probe' various options to list functions, see what
variables can be collected at any given point, experiment first
collecting without a filter, then filter, use it together with
'perf trace', 'perf top', with or without callchains, if it
explodes, please tell us!
- Introduce a new callchain mode: "folded", that will list per line
representations of all callchains for a give histogram entry,
facilitating 'perf report' output processing by other tools, such
as Brendan Gregg's flamegraph tools (Namhyung Kim)
E.g:
# perf report | grep -v ^# | head
18.37% 0.00% swapper [kernel.kallsyms] [k] cpu_startup_entry

|--12.07%--start_secondary

#
Becomes, in "folded" mode:
# perf report -g folded | grep -v ^# | head -5
18.37% 0.00% swapper [kernel.kallsyms] [k] cpu_startup_entry
12.07% cpu_startup_entry;start_secondary

NFC 4.5 pull request
This is the first NFC pull request for 4.5 and it brings: - A new driver for the STMicroelectronics ST95HF NFC chipset. The ST95HF is an NFC digital transceiver with an embedded analog front-end and as such relies on the Linux NFC digital implementation. This is the 3rd user of the NFC digital stack. - ACPI support for the ST st-nci and st21nfca drivers. - A small improvement for the nfcsim driver, as we can now tune the Rx delay through sysfs. - A bunch of minor cleanups and small fixes from Christophe Ricard, for a few drivers and the NFC core code. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWgsv0AAoJEIqAPN1PVmxKvukP/3eJwA+chAUF89/fqwqFTaJN fffLoOxx2OBIbTXD2VV36yw4bAo9tbKDAYBZiot3Ig7Kg0SeCJ5oPA9xCVnWPrEY hxFAldvl+lWQs8nrUOgUZItiFBeUPdfW9YX/yKhUZVc+602nUG/e/+6x8B5MhIce SAfgCyd0c16DApltP7sw1muyZMvsO6Ow6dyNzDUVYZuabvEhe3SLSj9KFJi7Thsp h41Iv+bwPLhwF4RXGA6rei/gdEDSMRohprdj3uTDiTarGW+OpcAO0zWACS5m4eR0 zF19+HjGPUk/LpFRaU31xX0ZQQjOTmmfsOt4FBb3P7oJx47egycsadLYPexeG7nj ruyS6ezlRX1I/tZsnyLNJK92mK5TXYLz2uJ8r2ii/BgPNE+AErB3zKCC+EjXzWhh AvClGu5b88WJLxoq3I3l5evPwGhebGZ8N/1uiFsHOxvzKVLgxwOmNLRGN4XXxB2i UbIHgBb6smsu/l+3q9R83kfoMaoWnr+OUIi2QPQVDt/K7t1LfsCuIhzcGSgo1VuW fGlA1iu+CNDknofeCl4JDo2UXAETO4gdKWw87GXeUcbbraLUczZeO7FFLZqxbMYc OCaPYshmVFeZRypYdRWDHw67ivj0/h+9iq4PP1XOROkRFH746dD/p4yamJwVi20B samZ8VPwzgH3/ohQJyX3 =VFUH -----END PGP SIGNATURE----- Merge tag 'nfc-next-4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-next Samuel Ortiz says: ==================== NFC 4.5 pull request This is the first NFC pull request for 4.5 and it brings: - A new driver for the STMicroelectronics ST95HF NFC chipset.

configfs: implement binary attributes
ConfigFS lacked binary attributes up until now. This patch introduces support for binary attributes in a somewhat similar manner of sysfs binary attributes albeit with changes that fit the configfs usage model. Problems that configfs binary attributes fix are everything that requires a binary blob as part of the configuration of a resource, such as bitstream loading for FPGAs, DTBs for dynamically created devices etc. Look at Documentation/filesystems/configfs/configfs.txt for internals and howto use them. This patch is against linux-next as of today that contains Christoph's configfs rework.
