048ccca8c1 Initial roundup of 4.5 merge window patches
- Remove usage of ib_query_device and instead store attributes in
   ib_device struct
 - Move iopoll out of block and into lib, rename to irqpoll, and use
   in several places in the rdma stack as our new completion queue
   polling library mechanism.  Update the other block drivers that
   already used iopoll to use the new mechanism too.
 - Replace the per-entry GID table locks with a single GID table lock
 - IPoIB multicast cleanup
 - Cleanups to the IB MR facility
 - Add support for 64bit extended IB counters
 - Fix for netlink oops while parsing RDMA nl messages

30f05309bd More power management and ACPI updates for v4.5-rc1
- Modify the driver core and the USB subsystem to allow USB devices
    to stay suspended over system suspend/resume cycles if they have
    been runtime-suspended already beforehand and fix some bugs on
    top of these changes (Tomeu Vizoso, Rafael Wysocki).
 
  - Update ACPICA to upstream revision 20160108, including updates
    of the ACPICA's copyright notices, a code fixup resulting from
    a regression fix that was necessary in the upstream code only
    (the regression fixed by it has never been present in Linux)
    and a compiler warning fix (Bob Moore, Lv Zheng).
 
  - Fix a recent regression in the cpuidle menu governor that broke
    it on practically all architectures other than x86 and make a
    couple of optimizations on top of that fix (Rafael Wysocki).
 
  - Clean up the selection of cpuidle governors depending on whether
    or not the kernel is configured for tickless systems (Jean Delvare).
 
  - Revert a recent commit that introduced a regression in the ACPI
    backlight driver, address the problem it attempted to fix in a
    different way and revert one more cosmetic change depending on
    the problematic commit (Hans de Goede).
 
  - Add two more ACPI backlight quirks (Hans de Goede).
 
  - Fix a few minor problems in the core devfreq code, clean it up
    a bit and update the MAINTAINERS information related to it
    (Chanwoo Choi, MyungJoo Ham).
 
  - Improve an error message in the ACPI fan driver (Andy Lutomirski).
 
  - Fix a recent build regression in the cpupower tool (Shreyas Prabhu).

Merge tag 'pm+acpi-4.5-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management and ACPI updates from Rafael Wysocki:
 "This includes fixes on top of the previous batch of PM+ACPI updates
  and some new material as well.

  From the new material perspective the most significant are the driver
  core changes that should allow USB devices to stay suspended over
  system suspend/resume cycles if they have been runtime-suspended
  already beforehand.  Apart from that, ACPICA is updated to upstream
  revision 20160108 (cosmetic mostly, but including one fixup on top of
  the previous ACPICA update) and there are some devfreq updates the
  didn't make it before (due to timing).

  A few recent regressions are fixed, most importantly in the cpuidle
  menu governor and in the ACPI backlight driver and some x86 platform
  drivers depending on it.

  Some more bugs are fixed and cleanups are made on top of that.

  Specifics:

   - Modify the driver core and the USB subsystem to allow USB devices
     to stay suspended over system suspend/resume cycles if they have
     been runtime-suspended already beforehand and fix some bugs on top
     of these changes (Tomeu Vizoso, Rafael Wysocki).

     compiler warning fix (Bob Moore, Lv Zheng).

d080827f85 libnvdimm for 4.5
1/ Media error handling: The 'badblocks' implementation that originated
    in md-raid is up-levelled to a generic capability of a block device.
    This initial implementation is limited to being consulted in the pmem
    block-i/o path.  Later, 'badblocks' will be consulted when creating
    dax mappings.
 
 2/ Raw block device dax: For virtualization and other cases that want
    large contiguous mappings of persistent memory, add the capability to
    dax-mmap a block device directly.
 
 3/ Increased /dev/mem restrictions: Add an option to treat all io-memory
    as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access while a driver is
    actively using an address range.  This behavior is controlled via the
    new CONFIG_IO_STRICT_DEVMEM option and can be overridden by the
    existing "iomem=relaxed" kernel command line option.
 
 4/ Miscellaneous fixes include a 'pfn'-device huge page alignment fix,
    block device shutdown crash fix, and other small libnvdimm fixes.

Merge tag 'libnvdimm-for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:
 "The bulk of this has appeared in -next and independently received a
  build success notification from the kbuild robot.  The 'for-4.5/block-
  dax' topic branch was rebased over the weekend to drop the "block
  device end-of-life" rework that Al would like to see re-implemented
  with a notifier, and to address bug reports against the badblocks
  integration.

  There is pending feedback against "libnvdimm: Add a poison list and
  export badblocks" received last week.  Linda identified some localized
  fixups that we will handle incrementally.

  Summary:

   - Media error handling: The 'badblocks' implementation that
     originated in md-raid is up-levelled to a generic capability of a
     block device.  This initial implementation is limited to being
     consulted in the pmem block-i/o path.  Later, 'badblocks' will be
     consulted when creating dax mappings.

   - Raw block device dax: For virtualization and other cases that want
     large contiguous mappings of persistent memory, add the capability
     to dax-mmap a block device directly.

   - Increased /dev/mem restrictions: Add an option to treat all

     while a driver is actively using an address range.  This behavior
     is controlled via the new CONFIG_IO_STRICT_DEVMEM option and can be

65cacec1ba selftests/x86: Test __kernel_sigreturn and __kernel_rt_sigreturn
The vdso-based sigreturn mechanism is fragile and isn't used by
modern glibc so, if we break it, we'll only notice when someone
tests an unusual libc.

Add an explicit selftest.

[ I wrote this while debugging a Bionic breakage -- my first guess
  was that I had somehow messed up sigreturn.  I've caused problems in
  that code before, and it's really easy to fail to notice it because
  there's nothing on a modern distro that needs vdso-based sigreturn. ]

67990608c8 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
     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)"

d1b39d41eb tools: Make list.h self-sufficient
Commit 7f5f873c6a ("rculist: Use WRITE_ONCE() when deleting from
reader-visible list") added the use of the WRITE_ONCE macro to the
kernel version of list.h, which broke the stacktool build because the
tools list.h includes the kernel list.h.

Avoid this type of situation in the future and make list.h
self-sufficient by copying the kernel list.h routines directly into
tools list.h.

This is a straight copy except for adjustments to the include statements
and copying of the tools-specific list routines (list_del_range and
list_for_each_from).

b0fb978e97 perf tools: Fix mmap2 event allocation in synthesize code
perf_event__synthesize_mmap_events() issues mmap2 events, but the memory
of that event is allocated using:

 mmap_event = malloc(sizeof(mmap_event->mmap) + machine->id_hdr_size);

If path of mmap source file is long (near PATH_MAX), random crash would
happen. Should use sizeof(mmap_event->mmap2).

8a59f3ccbc perf stat: Fix recort_usage typo
Markus reported gcc 6 complains when compiling perf stat command:

  builtin-stat.c:1591:27: error: ‘recort_usage’ defined but not used
  [-Werror=unused-const-variable]
   static const char * const recort_usage[] = {
                             ^~~~~~~~~~~~

I fixed the typo and realized we already export record_usage, so I also
prefixed it with stat (and included report_usage).

0f672809f9 selftests/x86: Disable the ldt_gdt_64 test for now
ldt_gdt.c relies on cross-cpu invalidation of SS to do one of
its tests.  On 32-bit builds, this works fine, but on 64-bit
builds, it only works if the kernel has proper SS sigcontext
handling for 64-bit user programs.

Since the SS fixes are currently reverted, restrict the test
case to 32 bits for now.

In principle, I could change the test to use a different segment
register, but it would be messy: CS can't point to the LDT for
64-bit code, and the other registers don't result in immediate
faults because they aren't reloaded on kernel -> user
transitions.

When we fix sigcontext (in 4.6?), we can revert this.

   - 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)

b0500c169b perf test: Reset err after using it hold errcode in hist testcases
All hists test cases forget to reset err after using it to hold an
error code. If error occure in setup_fake_machine() it incorrectly
return TEST_OK.

This patch fixes it.

71b3ee7e65 perf test: Fix false TEST_OK result for 'perf test hist'
Commit 71d6de64fe ("perf test: Fix hist testcases when kptr_restrict is on")
solves a double free problem when 'perf test hist' calling
setup_fake_machine(). However, the result is still incorrect. For example:

  $ ./perf test -v 'filtering hist entries'
  25: Test filtering hist entries                              :
  --- start ---
  test child forked, pid 4186
  Cannot create kernel maps
  test child finished with 0
  ---- end ----
  Test filtering hist entries: Ok

In this case the body of this test is not get executed at all, but the
result is 'Ok'.

Actually, in setup_fake_machine() there's no need to create real kernel
maps. What we want are the fake maps. This patch removes the
machine__create_kernel_maps() in setup_fake_machine(), so it won't be
affected by kptr_restrict setting.

Test result:

  $ cat /proc/sys/kernel/kptr_restrict
  1
  $ ~/perf test -v hist
  15: Test matching and linking multiple hists                 :
  --- start ---
  test child forked, pid 24031
  test child finished with 0
  ---- end ----
  Test matching and linking multiple hists: Ok

0c4d40d580 tools build: Add BPF feature check to test-all
The test-all.c file doesn't check BPF related features. For an
environment with all other features enabled, BPF would be considered
enabled without doing real feature check.

This patch adds test-bpf.c into test-all.c.

d5ef314035 perf bpf: Fix build breakage due to libbpf
perf build is currently (v4.4-rc5) broken on powerpc:

  bpf.c:28:4: error: #error __NR_bpf not defined. libbpf does not support
  your arch.
   #  error __NR_bpf not defined. libbpf does not support your arch.
      ^

Fix this by including tools/scripts/Makefile.arch for the proper $ARCH
macro. While at it, remove redundant LP64 macro definition.

Also, since libbpf require $(srctree) now, detect the path of srctree
like perf.

without directly including it from perf's directory. Libbpf would

In this case a '-lutil' should be appended to -lpython2.7.

(I know we have --start-group and --end-group. I can see them in command
line of collect2 by strace. However it doesn't work. Seems I have a
broken environment?)

9061cbe62a Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU updates from Ingo Molnar:
 "The changes in this cycle were:

   - Adding transitivity uniformly to rcu_node structure ->lock
     acquisitions.  (This is implemented by the first two commits on top
     of v4.4-rc2 due to the pervasive nature of this change.)

   - Documentation updates, including RCU requirements.

   - Expedited grace-period changes.

   - Miscellaneous fixes.

   - Linked-list fixes, courtesy of KTSAN.

   - Torture-test updates.

   - Late-breaking fix to sysrq-generated crash.

  One thing I should note is that these pieces of documentation are
  fairly large files:

    .../RCU/Design/Requirements/Requirements.html      | 2897 ++++++++++++++++++++
    .../RCU/Design/Requirements/Requirements.htmlx     | 2741 ++++++++++++++++++

  and are written in HTML, not the usual .txt style.  I hope they are
  fine"

Paul McKenney explains the html docs:
 "For whatever it is worth, the reason for this unconventional choice
  was that attempts to do the diagrams in ASCII art failed miserably.

  And attempts to do ASCII art for the upcoming documentation of the
  data structures failed even more miserably"
