Wanpeng Li 5473e0cc37 sched: 'Annotate' migrate_tasks()

As Peterz pointed out:

| So the normal rules for changing task_struct::cpus_allowed are holding
| both pi_lock and rq->lock, such that holding either stabilizes the mask.
|
| This is so that wakeup can happen without rq->lock and load-balance
| without pi_lock.
|
| From this we already get the relaxation that we can omit acquiring
| rq->lock if the task is not on the rq, because in that case
| load-balancing will not apply to it.
|
| ** these are the rules currently tested in do_set_cpus_allowed() **
|
| Now, since __set_cpus_allowed_ptr() uses task_rq_lock() which
| unconditionally acquires both locks, we could get away with holding just
| rq->lock when on_rq for modification because that'd still exclude
| __set_cpus_allowed_ptr(), it would also work against
| __kthread_bind_mask() because that assumes !on_rq.
|
| That said, this is all somewhat fragile.
|
| Now, I don't think dropping rq->lock is quite as disastrous as it
| usually is because !cpu_active at this point, which means load-balance
| will not interfere, but that too is somewhat fragile.
|
| So we end up with a choice of two fragile..

This patch fixes it by following the rules for changing
task_struct::cpus_allowed with both pi_lock and rq->lock held.

Frederic Weisbecker 7c8bb6cb95 nohz: Assert existing housekeepers when nohz full enabled
The code ensures that when nohz full is running, at least the
boot CPU serves as a housekeeper and it can't be later offlined.

Let's assert this assumption to make sure that we have CPUs to
handle unbound jobs like workqueues and timers while nohz full
CPUs run undisturbed.

Also improve the comments on housekeeper offlining prevention.

Vatika Harlalka 9642d18eee nohz: Affine unpinned timers to housekeepers
The problem addressed in this patch is about affining unpinned
timers. Adaptive or Full Dynticks CPUs are currently disturbed
by unnecessary jitter due to firing of such timers on them.

This patch will affine timers to online CPUs which are not full
dynticks in NOHZ_FULL configured systems. It should not
introduce overhead in nohz full off case due to static keys.

Linus Torvalds 8d01b66b4f ARM: SoC 64-bit changes for v4.3
Here's our branch of ARM64 contents for this merge window.
 
 Most of this is DT contents for new SoCs (or those who have seen new
 device support added). Maybe we should stop separating out the arm64
 contents here to avoid the kind of internal conflicts as we got this
 time around, where 32- and 64-bit contents conflicted.
 
 Anyhow, on the actual contents:
 
 New SoCs:
 
 - Broadcom North Star 2 (ns2)
 - Marvell Berlin4CT
 - Mediatek MT6795
 - Rockchip RK3368
 
 In addition, there are enhancements for the following platforms:
 
 - Mediatek MT8173: cpuidle-dt updates, misc other additions
 - ZyncMP: A bunch of devices added to the existing DTSI
 - Qualcomm MSM8916 and APQ8016 updates for USB, etc.
 
 + A handful of other updates for various platforms

Linus Torvalds 102178108e ARM: SoC driver updates for v4.3
Some releases this branch is nearly empty, others we have more stuff. It
 tends to gather drivers that need SoC modification or dependencies such
 that they have to (also) go in through our tree.
 
 For this release, we have merged in part of the reset controller tree
 (with handshake that the parts we have merged in will remain stable),
 as well as dependencies on a few clock branches.
 
 In general, new items here are:
 
 - Qualcomm driver for SMM/SMD, which is how they communicate with the
   coprocessors on (some) of their platforms
 - Memory controller work for ARM's PL172 memory controller
 - Reset drivers for various platforms
 - PMU power domain support for Marvell platforms
 - Tegra support for T132/T210 SoCs: PMC, fuse, memory controller per-SoC support

Linus Torvalds c5fc249862 ARM: SoC cleanups for v4.3
A large cleanup branch this release, with a healthy 10k negative line delta.
 
 Most of this is removal of legacy (non-DT) support of shmobile
 platforms. There is also removal of two non-DT platforms on OMAP,
 and the plat-samsung directory is cleaned out by moving most of the
 previously shared-location-but-not-actually-shared files from there to
 the appropriate mach directories instead.
 
 There are other sets of changes in here as well:
 
  - Rob Herring removed use of set_irq_flags under all platforms and
    moved to genirq alternatives
  - A series of timer API conversions to set-state interface
  - ep93xx, nomadik and ux500 cleanups from Linus Walleij
  - __init annotation fixes from Nicolas Pitre

 "The biggest change in this cycle is the rewrite of the main SMP load
  balancing metric: the CPU load/utilization.  The main goal was to make
  the metric more precise and more representative - see the changelog of
  this commit for the gory details:

    9d89c257df ("sched/fair: Rewrite runnable load and utilization average tracking")

  It is done in a way that significantly reduces complexity of the code:

    5 files changed, 249 insertions(+), 494 deletions(-)

  and the performance testing results are encouraging.  Nevertheless we
  need to keep an eye on potential regressions, since this potentially
  affects every SMP workload in existence.

   - Add support for using several Intel PT features (CYC, MTC packets),
     the relevant documentation was updated in:
         tools/perf/Documentation/intel-pt.txt
     briefly describing those packets, its purposes, how to configure
     them in the event config terms and relevant external documentation
     for further reading.  (Adrian Hunter)

   - Introduce support for probing at an absolute address, for user and
     kernel 'perf probe's, useful when one have the symbol maps on a
     developer machine but not on an embedded system.  (Wang Nan)

   - Add Intel BTS support, with a call-graph script to show it and PT
     in use in a GUI using 'perf script' python scripting with
     postgresql and Qt.  (Adrian Hunter)

   - Allow selecting the type of callchains per event, including
     disabling callchains in all but one entry in an event list, to save
     space, and also to ask for the callchains collected in one event to
     be used in other events.  (Kan Liang)

   - Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho
     de Melo)
       * A bunch more translate file/pathnames from pointers to strings.
       * Convert numbers to strings for the 'keyctl' syscall 'option'
         arg.
       * Add missing 'clockid' entries.

   - Introduce 'srcfile' sort key: (Andi Kleen)

       # perf record -F 10000 usleep 1
       # perf report --stdio --dsos '[kernel.vmlinux]' -s srcfile
       <SNIP>
       # Overhead  Source File
          26.49%  copy_page_64.S
           5.49%  signal.c
           0.51%  msr.h
       #

     It can be combined with other fields, for instance, experiment with
     '-s srcfile,symbol'.

     There are some oddities in some distros and with some specific
     DSOs, being investigated, so your mileage may vary.

   - Support per-event 'freq' term: (Namhyung Kim)

       $ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 sleep 1
       $ perf evlist -F
       cpu/instructions,freq=1234/: sample_freq=1234
       cycles: sample_period=1000
       $

   - Deref sys_enter pointer args with contents from probe:vfs_getname,
     showing pathnames instead of pointers in many syscalls in 'perf
     trace'.  (Arnaldo Carvalho de Melo)

   - Stop collecting /proc/kallsyms in perf.data files, saving about
     4.5MB on a typical x86-64 system, use the the symbol resolution
     routines used in all the other tools (report, top, etc) now that we
     can ask libtraceevent to use perf's symbol resolution code.
     (Arnaldo Carvalho de Melo)

   - Allow filtering out of perf's PID via 'perf record --exclude-perf'.
     (Wang Nan)

   - 'perf trace' now supports syscall groups, like strace, i.e:

       $ trace -e file touch file

     Will expand 'file' into multiple, file related, syscalls.  More
     work needed to add extra groups for other syscall groups, and also
     to complement what was added for the 'file' group, included as a
     proof of concept.  (Arnaldo Carvalho de Melo)

   - Add lock_pi stresser to 'perf bench futex', to test the kernel code
     related to FUTEX_(UN)LOCK_PI.  (Davidlohr Bueso)

   - Let user have timestamps with per-thread recording in 'perf record'
     (Adrian Hunter)

Linus Torvalds f36fc04e4c The clk framework changes for 4.3 are mostly updates to existing drivers
and the addition of new clock drivers. Stephen Boyd has also done a lot
 of subsystem-wide driver clean-ups (thanks!). There are also fixes to
 the framework core and changes to better split clock provider drivers
 from clock consumer drivers.

Linus Torvalds cf9d615f7f regulator: Updates for v4.3
The biggest changes in the core this time around have been some
 refactorings that move us towards being able to drop the list of
 regulators maintained by the core and instead just use the driver model
 list maintained for the class devices for regulators which will make the
 code smaller and avoid some potential bugs.  Otherwise another fairly
 quiet release for the regulator API, highlights include:
 
  - A new API for setting voltages based on a minimum, target, maximum
    triplet.
  - Support for continuous voltage ranges rather than tables of explicit
    steps in the PWM regulator, requiring less explicit configuration.
  - New driver support for Dialog DA9215, Maxim 77843, Mediatek MT6311
    and Qualcomm RPM.

Merge tag 'regulator-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "The biggest changes in the core this time around have been some
  refactorings that move us towards being able to drop the list of
  regulators maintained by the core and instead just use the driver
  model list maintained for the class devices for regulators which will
  make the code smaller and avoid some potential bugs.

  Otherwise another fairly quiet release for the regulator API,
  highlights include:

   - a new API for setting voltages based on a minimum, target, maximum
     triplet

   - support for continuous voltage ranges rather than tables of
     explicit steps in the PWM regulator, requiring less explicit
     configuration

   - new driver support for Dialog DA9215, Maxim 77843, Mediatek MT6311
     and Qualcomm RPM"

 "Here is the big tty/serial driver update for 4.3-rc1.

  Not many major things, a number of driver updates and changes, and the
  8250 driver got split up a bit to make it easier to work with by
  moving some functions to a new file.  Full details are in the
  shortlog.

  All have been in linux-next with no reported issues"

Linus Torvalds 2f37d65a6a Staging driver patches for 4.3-rc1
Here is the big staging driver updates for 4.3-rc1.
 
 Lots of things all over the place, almost all of them trivial fixups and
 changes.  The usual IIO updates and new drivers and we have added the
 MOST driver subsystem which is getting cleaned up in the tree.  The
 ozwpan driver is finally being deleted as it is obviously abandoned and
 no one cares about it.
 
 Full details are in the shortlog, and all of these have been in
 linux-next with no reported issues.

Here is the new patches for the driver core / sysfs for 4.3-rc1.
 
 Very small number of changes here, all the details are in the shortlog,

Linus Torvalds 1c00038c76 Char/Misc driver patches for 4.3-rc1
Here's the "big" char/misc driver update for 4.3-rc1.
 
 Not much really interesting here, just a number of little changes all
 over the place, and some nice consolidation of the nvmem drivers to a
 common framework.  As usual, the mei drivers stand out as the largest
 "churn" to handle new devices and features in their hardware.
 
 All have been in linux-next for a while with no issues.
