Merge branch 'for-linus-clk' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull clkdev updates from Russell King:
"This series addresses some breakage in clkdev caused by a previous
patch set from the clk tree which introduced per-user clk structures.
This basically renamed the existing 'struct clk' to 'struct clk_hw',
and introduced a new 'struct clk'.
This change will break anyone using clk_add_alias() with the common
clk code enabled. Thankfully, the intersection of users of
clk_add_alias() and those using the common clk code is practically
zero, but this is something which should be fixed to keep the code
sane.
The problem is that clk_add_alias() does this:
r = clk_get(...);
l = clkdev_alloc(r, ...);
clk_put(...);
which causes the alias to store a pointer to 'r', which has been
freed.
The original patch set tried to work around this problem incorrectly -
at clk_get() time, it tried to convert the struct clk to a struct
clk_hw, and then creating a new struct clk from that. Clearly, if the
original struct clk has been freed, then we have a use-after-free bug.
We have other places in the tree which do something similar, so this
series also addresses those locations too.
This series addresses this problem by converting clkdev to store and
use the clk_hw pointer. This allows clk_get() to only have to create
it's per-user struct clk from the clk_hw. We can also get to the
desired clk_hw at clk_add_alias() or clk lookup creation time, when
the struct clk is "alive".
We also perform some cleanups of the code:
- replacing looped calls to clkdev_add() with clkdev_add_table()
- replacing open-coded lookup allocation (which should have been
using clkdev_alloc()) and subsequent clkdev_add() with
clkdev_create()
- replacing open-coded clk_add_alias() with clk_add_alias()"

Merge tag 'pm+acpi-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management and ACPI updates from Rafael Wysocki:
"The rework of backlight interface selection API from Hans de Goede
stands out from the number of commits and the number of affected
places perspective. The cpufreq core fixes from Viresh Kumar are
quite significant too as far as the number of commits goes and because
they should reduce CPU online/offline overhead quite a bit in the
majority of cases.
From the new featues point of view, the ACPICA update (to upstream
revision 20150515) adding support for new ACPI 6 material to ACPICA is
the one that matters the most as some new significant features will be
based on it going forward. Also included is an update of the ACPI
device power management core to follow ACPI 6 (which in turn reflects
the Windows' device PM implementation), a PM core extension to support
wakeup interrupts in a more generic way and support for the ACPI _CCA
device configuration object.
The rest is mostly fixes and cleanups all over and some documentation
updates, including new DT bindings for Operating Performance Points.
There is one fix for a regression introduced in the 4.1 cycle, but it
adds quite a number of lines of code, it wasn't really ready before
Thursday and you were on vacation, so I refrained from pushing it on
the last minute for 4.1.

This is the big bulk of GPIO changes queued for the v4.2
kernel series:
- A big set of cleanups to the aged sysfs interface from
Johan Hovold. To get these in, v4.1-rc3 was merged into
the tree as the first patch in that series had to go
into stable. This makes the locking much more fine-grained
(get rid of the "big GPIO lock(s)" and store states in the
GPIO descriptors.
- Rename gpiod_[g|s]et_array() to gpiod_[g|s]et_array_value()
to avoid confusions.
- New drivers for:
- NXP LPC18xx (currently LPC1850)
- NetLogic XLP
- Broadcom STB SoC's

Pull gpio updates from Linus Walleij:
"This is the big bulk of GPIO changes queued for the v4.2 kernel
series:
- a big set of cleanups to the aged sysfs interface from Johan
Hovold. To get these in, v4.1-rc3 was merged into the tree as the
first patch in that series had to go into stable. This makes the
locking much more fine-grained (get rid of the "big GPIO lock(s)"
and store states in the GPIO descriptors.
- rename gpiod_[g|s]et_array() to gpiod_[g|s]et_array_value() to
avoid confusions.
- New drivers for:
* NXP LPC18xx (currently LPC1850)
* NetLogic XLP
* Broadcom STB SoC's
* Axis ETRAXFS
* Zynq Ultrascale+ (subdriver)
- ACPI:
* make it possible to retrieve GpioInt resources from a GPIO

Merge branch 'x86-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 core updates from Ingo Molnar:
"There were so many changes in the x86/asm, x86/apic and x86/mm topics
in this cycle that the topical separation of -tip broke down somewhat -
so the result is a more traditional architecture pull request,
collected into the 'x86/core' topic.
The topics were still maintained separately as far as possible, so
bisectability and conceptual separation should still be pretty good -
but there were a handful of merge points to avoid excessive
dependencies (and conflicts) that would have been poorly tested in the
end.
The next cycle will hopefully be much more quiet (or at least will
have fewer dependencies).
The main changes in this cycle were:
* x86/apic changes, with related IRQ core changes: (Jiang Liu, Thomas
Gleixner)
- This is the second and most intrusive part of changes to the x86
interrupt handling - full conversion to hierarchical interrupt
domains:
[IOAPIC domain] -----
|
[MSI domain] --------[Remapping domain] ----- [ Vector domain ]
| (optional) |
[HPET MSI domain] ----- |
|
[DMAR domain] -----------------------------
|
[Legacy domain] -----------------------------
This now reflects the actual hardware and allowed us to distangle
the domain specific code from the underlying parent domain, which
can be optional in the case of interrupt remapping. It's a clear
separation of functionality and removes quite some duct tape
constructs which plugged the remap code between ioapic/msi/hpet
and the vector management.
- Intel IOMMU IRQ remapping enhancements, to allow direct interrupt
injection into guests (Feng Wu)
* x86/asm changes:
- Tons of cleanups and small speedups, micro-optimizations. This
is in preparation to move a good chunk of the low level entry
code from assembly to C code (Denys Vlasenko, Andy Lutomirski,
Brian Gerst)
- Moved all system entry related code to a new home under
arch/x86/entry/ (Ingo Molnar)
- Removal of the fragile and ugly CFI dwarf debuginfo annotations.
Conversion to C will reintroduce many of them - but meanwhile
they are only getting in the way, and the upstream kernel does
not rely on them (Ingo Molnar)
- NOP handling refinements. (Borislav Petkov)
* x86/mm changes:
- Big PAT and MTRR rework: making the code more robust and
preparing to phase out exposing direct MTRR interfaces to drivers -
in favor of using PAT driven interfaces (Toshi Kani, Luis R
Rodriguez, Borislav Petkov)
- New ioremap_wt()/set_memory_wt() interfaces to support
Write-Through cached memory mappings. This is especially
important for good performance on NVDIMM hardware (Toshi Kani)
* x86/ras changes:
- Add support for deferred errors on AMD (Aravind Gopalakrishnan)
This is an important RAS feature which adds hardware support for
poisoned data. That means roughly that the hardware marks data
which it has detected as corrupted but wasn't able to correct, as
poisoned data and raises an APIC interrupt to signal that in the
form of a deferred error. It is the OS's responsibility then to
take proper recovery action and thus prolonge system lifetime as
far as possible.
- Add support for Intel "Local MCE"s: upcoming CPUs will support
CPU-local MCE interrupts, as opposed to the traditional system-
wide broadcasted MCE interrupts (Ashok Raj)
- Misc cleanups (Borislav Petkov)
* x86/platform changes:
- Intel Atom SoC updates
... and lots of other cleanups, fixlets and other changes - see the
shortlog and the Git log for details"
* 'x86-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (222 commits)
x86/hpet: Use proper hpet device number for MSI allocation

x86/mm/pat, drivers/media/ivtv: Use arch_phys_wc_add() and require PAT disabled

HSI: cmt_speech: fix timestamp interface
The user interface for timestamps in the new cmt_speech driver is broken in multiple ways: - The layout is incompatible between 32-bit and 64-bit user space, because of the size differences in 'struct timespec'. This means that the driver can not work when used with 32-bit user space on a 64-bit kernel. - As there are plans to change 32-bit user space to use a 64-bit time_t type in the future, it will also be incompatible with new 32-bit user space. - It is using ktime_get_ts under it's deprecated alias (do_posix_clock_monotonic_gettime). To keep support for the user space tools written for this driver (which have lived many years out-of-tree), the interface has been hardened to unsigned 32-bit values.

Merge branch 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 FPU updates from Ingo Molnar:
"This tree contains two main changes:
- The big FPU code rewrite: wide reaching cleanups and reorganization
that pulls all the FPU code together into a clean base in
arch/x86/fpu/.
The resulting code is leaner and faster, and much easier to
understand. This enables future work to further simplify the FPU
code (such as removing lazy FPU restores).
By its nature these changes have a substantial regression risk: FPU
code related bugs are long lived, because races are often subtle
and bugs mask as user-space failures that are difficult to track
back to kernel side backs. I'm aware of no unfixed (or even
suspected) FPU related regression so far.
- MPX support rework/fixes. As this is still not a released CPU

a 'perf top' session can instantly become a 'perf report'
one, i.e. going from dynamic analysis to a static one,
returning to a dynamic one is possible, to toogle the
modes, just press 'f' to 'freeze/unfreeze' the sampling. (Arnaldo Carvalho de Melo)
- Make Ctrl-C stop processing on TUI, allowing interrupting the load of big
perf.data files (Namhyung Kim)
'perf probe': (Masami Hiramatsu)
- Support glob wildcards for function name
- Support $params special probe argument: Collect all function arguments
- Make --line checks validate C-style function name.

- Improve --filter support for 'perf probe', allowing using its arguments
on other commands, as --add, --del, etc.
'perf sched':
- Add option in 'perf sched' to merge like comms to lat output (Josef Bacik)

upcoming threaded perf report support, but also lots of other work -
and fixes and other improvements. See (much) more details in the

cpuidle: powernv/pseries: Auto-promotion of snooze to deeper idle state
The idle cpus which stay in snooze for a long period can degrade the perfomance of the sibling cpus. If the cpu stays in snooze for more than target residency of the next available idle state, then exit from snooze. This gives a chance to the cpuidle governor to re-evaluate the last idle state of the cpu to promote it to deeper idle states.

x86: Load __USER_DS into DS/ES after resume
Srinivas Pandruvada reported a problem with system resume from suspend-to-RAM on 32-bit x86 systems where the DS register of the CPU is set to __KERNEL_DS instead of __USER_DS on return to user space which cases a General Protection Fault to occur. The issue is that DS is set to __KERNEL_DS by the ACPI resume code path while the SYSEXIT path never reloads DS/ES. It assumes they are still __USER_DS set at the SYSENTER time (Brian Gerst), so if the return to user space happens to be through SYSEXIT, it will lead to the reported GPF. Fix the problem by setting the DS and ES registers to __USER_DS as expected by the SYSEXIT path.

PM / OPP: Allow multiple OPP tables to be passed via DT
On some platforms (Like Qualcomm's SoCs), it is not decided until runtime on what OPPs to use. The OPP tables can be fixed at compile time, but which table to use is found out only after reading some efuses (sort of an prom) and knowing characteristics of the SoC. To support such platform we need to pass multiple OPP tables per device and hardware should be able to choose one and only one table out of those. Update operating-points-v2 bindings to support that.
