We mostly keep defconfigs updates on a separate branch due to their tendency
to conflict between platforms and this encourages more careful separation of
code changes and config changes.
Most updates here are minor tweaks, enabling new drivers for various platforms,
and so on. Renesas also removed one defconfig (marzen_defconfig).

"Ladies and gentlemen, we proudly announce to you the latest branch of
ARM device tree contents for the mainline kernel. Come and see, come
and see!
No less than twentythree thousand lines of additions! Just imagine the
joy you will have of using your mainline kernel on newly supported
hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or
UniPhier hardware!
For those of you feeling less adventurous, added hardware support on
platforms such as TI DM814x and Gumstix Overo platforms might be more
of your liking.
We've got something for everyone here!
Ahem. Cough. So, anyway...

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

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 patch also moves the REG() and REG_END() macros into the

SMPL_REG/SMPL_REG_END to avoid clashes with other header files.

'user_policy' caches properties of a policy that are set by userspace.
And these must be updated only if cpufreq core was successful in
updating them based on request from user space.
In store_scaling_governor(), we are updating user_policy.policy and
user_policy.governor even if cpufreq_set_policy() failed. That's
incorrect.
Fix this by updating user_policy.* only if we were successful in

Mediatek MT8173 is an ARMv8 based quad-core (2*Cortex-A53 and
2*Cortex-A72) SoC with duall clusters. For each cluster, two voltage
inputs, Vproc and Vsram are supplied by two regulators. For the big
cluster, two regulators come from different PMICs. In this case, when
scaling voltage inputs of the cluster, the voltages of two regulator
inputs need to be controlled by software explicitly under the SoC
specific limitation:
100mV < Vsram - Vproc < 200mV
which is called 'voltage tracking' mechanism. And when scaling the
frequency of cluster clock input, the input MUX need to be parented to
another "intermediate" stable PLL first and reparented to the original
PLL once the original PLL is stable at the target frequency. This patch
implements those mechanisms to enable CPU DVFS support for Mediatek
MT8173 SoC.

Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
User visible changes:
- Add ability to specify to select which registers to record,
to reduce the size of perf.data files, and also allow printing
the registers in 'perf script': (Stephane Eranian)
# perf record --intr-regs=AX,SP usleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.016 MB perf.data (8 samples) ]
# perf script -F ip,sym,iregs | tail -5

Pull NOHZ updates from Ingo Molnar:
"The main changes, mostly written by Frederic Weisbecker, include:
- Fix some jiffies based cputime assumptions. (No real harm because
the concerned code isn't used by full dynticks.)
- Simplify jiffies <-> usecs conversions. Remove dead code.
- Remove early hacks on nohz full code that avoided messing up idle
nohz internals. Now nohz integrates well full and idle and such
hack have become needless.
- Restart nohz full tick from irq exit. (A simplification and a
preparation for future optimization on scheduler kick to nohz
full)
- Code cleanups.
- Tile driver isolation enhancement on top of nohz. (Chris Metcalf)"
* 'timers-nohz-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
nohz: Remove useless argument on tick_nohz_task_switch()

Pull scheduler fix from Ingo Molnar:
"This is a leftover scheduler fix from the v4.2 cycle"
* 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
sched: Fix cpu_active_mask/cpu_online_mask race
Pull scheduler updates from Ingo Molnar:
"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.
This work comes from Yuyang Du.
Other changes:
- SCHED_DL updates. (Andrea Parri)
- Simplify architecture callbacks by removing finish_arch_switch().
(Peter Zijlstra et al)
- cputime accounting: guarantee stime + utime == rtime. (Peter
Zijlstra)
- optimize idle CPU wakeups some more - inspired by Facebook server
loads. (Mike Galbraith)
- stop_machine fixes and updates. (Oleg Nesterov)
- Introduce the 'trace_sched_waking' tracepoint. (Peter Zijlstra)
- sched/numa tweaks. (Srikar Dronamraju)
- misc fixes and small cleanups"
