Linus Torvalds 404a47410c Merge branch 'uaccess' (batched user access infrastructure) 
Expose an interface to allow users to mark several accesses together as
being user space accesses, allowing batching of the surrounding user
space access markers (SMAP on x86, PAN on arm64, domain register
switching on arm).

This is currently only used for the user string lenth and copying
functions, where the SMAP overhead on x86 drowned the actual user
accesses (only noticeable on newer microarchitectures that support SMAP
in the first place, of course).

* user access batching branch:
  Use the new batched user accesses in generic user string handling
  Add 'unsafe' user access functions for batched accesses
  x86: reorganize SMAP handling in user space accesses

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).

     the ACPICA's copyright notices, a code fixup resulting from a

     compiler warning fix (Bob Moore, Lv Zheng).

     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

Linus Torvalds 9638685e32 ARM: SoC driver updates for v4.5 
Driver updates for ARM SoCs. Some for SoC-family code under drivers/soc,
 but also some other driver updates that don't belong anywhere else. We also
 bring in the drivers/reset code through arm-soc.
 
 Some of the larger updates:
 
 - Qualcomm support for SMEM, SMSM, SMP2P. All used to communicate with other
   parts of the chip/board on these platforms, all proprietary protocols that
   don't fit into other subsystems and live in drivers/soc for now.
 
 - System bus driver for UniPhier
 - Driver for the TI Wakeup M3 IPC device
 
 - Power management for Raspberry PI
 
 + Again a bunch of other smaller updates and patches.

Linus Torvalds 03d7d12415 ARM: 64-bit defconfig updates for v4.5 
As mentioned earlier, we usually bake this into the general "arm64" branch,
 but this release we have partitioned up the updates a bit more.
 
 Most of these updates are enabling new SoCs in the single defconfig for 64-bit,
 Renesas R8A7795, a number of Tegra options, Socionext Uniphier and a handful
 of new options for other platforms as well.

Linus Torvalds f9cd69fe5e ARM: SoC defconfig updates for v4.5 
As usual, a bunch of commits, mostly adding drivers and other options to
 defconfigs because it makes sense to have them enabled on various development
 or product boards. Too much to enumerate each here.
 
 There's an introduction of a pxa_defconfig, since PXA finally will allow
 building a shared kernel for all boards. With this, we can hopefully
 remove a bunch of individual defconfigs down the road but it requires
 a bit of real life testing and transition period.

Linus Torvalds 6d1c244803 ARM: DT updates for v4.5 
As usual, the bulk of this release is again DT file contents.
 
 There's a huge number of changes here, and it's challenging to give a crisp
 overview of just what is in here. To start with:
 
 New boards:
 
 - TI-based DM3730 from LogicPD (Torpedo)
 - Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
 - Raspberry Pi 2 DT files
 - Watchdog on Meson8b
 - Veyron-mickey (ASUS Chromebit) DTS
 - Rockchip rk3228 SoC and eval board
 - Sigma Designs Tango4
 
 Improvements:
 
 - Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
 - Misc new devices for Rockchip rk3036 and rk3288
 - Allwinner updates for misc SoCs and systems
 
 ... and a _large_ number of other changes across the field. Devices
 added to SoC DTSI and board DTS files for a number of SoC vendors, new
 product boards on already-supported SoCs, cleanups and refactorings of
 existing DTS/DTSI files and a bunch of other changes.

Linus Torvalds 6b5a12dbca ARM: SoC multiplatform code changes for v4.5 
This branch is the culmination of 5 years of effort to bring the ARMv6
 and ARMv7 platforms together such that they can all be enabled and
 boot the same kernel. It has been a tremendous amount of cleanup and
 refactoring by a huge number of people, and creation of several new
 (and major) subsystems to better abstract out all the platform details
 in an appropriate manner.
 
 The bulk of this branch is a large patchset from Arnd that brings several
 of the more minor and older platforms we have closer to multiplatform
 support.  Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview
 Much of this is moving around header files from old mach directories,
 but there are also some cleanup patches of debug_ll (lowlevel debug
 per-platform options) and other parts.
 
 Linus Walleij also has some patchs to clean up the older ARM Realview
 platforms by finally introducing DT support, and Rob Herring has some
 for ARM Versatile which is now DT-only. Both of these platforms are
 now multiplatform.
 
 Finally, a couple of patches from Russell for Dove PMU, and a fix from
 Valentin Rothberg for Exynos ADC, which were rebased on top of the
 series to avoid conflicts.

Linus Torvalds 5083c54264 ARM: SoC cleanups for v4.5 
A smallish number of general cleanup commits this release cycle. Some
 of these are minor tweaks:
 
 - shmobile change of binding for their GIC (using arm,pl390 now)
 - ARCH_RENESAS introduction
 - Misc other renesas updates
 
 There's also a couple of treewide commits from Masahiro Yamada cleaning up
 const/__initconst for SMP operation structs and a switch to using "depends
 on" instead of if-constructs on most of the Kconfig platform targets.

Christoph Hellwig 0d4a619b64 dma-mapping: make the generic coherent dma mmap implementation optional 
This series converts all remaining architectures to use dma_map_ops and
the generic implementation of the DMA API.  This not only simplifies the
code a lot, but also prepares for possible future changes like more
generic non-iommu dma_ops implementations or generic per-device
dma_map_ops.

This patch (of 16):

We have a couple architectures that do not want to support this code, so
add another Kconfig symbol that disables the code similar to what we do
for the nommu case.

This hooks up UBSAN support for PowerPC.

So far it's found some interesting cases where we don't properly sanitise
input to shifts, including one in our futex handling.  Nothing critical,
but interesting and worth fixing.

Andrey Ryabinin c6d308534a UBSAN: run-time undefined behavior sanity checker 
UBSAN uses compile-time instrumentation to catch undefined behavior
(UB).  Compiler inserts code that perform certain kinds of checks before
operations that could cause UB.  If check fails (i.e.  UB detected)
__ubsan_handle_* function called to print error message.

So the most of the work is done by compiler.  This patch just implements
ubsan handlers printing errors.

GCC has this capability since 4.9.x [1] (see -fsanitize=undefined
option and its suboptions).
However GCC 5.x has more checkers implemented [2].
Article [3] has a bit more details about UBSAN in the GCC.

[1] - https://gcc.gnu.org/onlinedocs/gcc-4.9.0/gcc/Debugging-Options.html
[2] - https://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html
[3] - http://developerblog.redhat.com/2014/10/16/gcc-undefined-behavior-sanitizer-ubsan/

Issues which UBSAN has found thus far are:

 * out-of-bounds access - 97840cb67f ("netfilter: nfnetlink: fix

undefined shifts:

Rasmus Villemoes a051216427 powerpc/fadump: rename cpu_online_mask member of struct fadump_crash_info_header 
The four cpumasks cpu_{possible,online,present,active}_bits are exposed
readonly via the corresponding const variables cpu_xyz_mask.  But they are
also accessible for arbitrary writing via the exposed functions
set_cpu_xyz.  There's quite a bit of code throughout the kernel which
iterates over or otherwise accesses these bitmaps, and having the access
go via the cpu_xyz_mask variables is nowadays [1] simply a useless
indirection.

It may be that any problem in CS can be solved by an extra level of
indirection, but that doesn't mean every extra indirection solves a
problem.  In this case, it even necessitates some minor ugliness (see
4/6).

Patch 1/6 is new in v2, and fixes a build failure on ppc by renaming a
struct member, to avoid problems when the identifier cpu_online_mask
becomes a macro later in the series.  The next four patches eliminate the
cpu_xyz_mask variables by simply exposing the actual bitmaps, after
renaming them to discourage direct access - that still happens through
cpu_xyz_mask, which are now simply macros with the same type and value as
they used to have.

After that, there's no longer any reason to have the setter functions be
out-of-line: The boolean parameter is almost always a literal true or
false, so by making them static inlines they will usually compile to one
or two instructions.

For a defconfig build on x86_64, bloat-o-meter says we save ~3000 bytes.
We also save a little stack (stackdelta says 127 functions have a 16 byte
smaller stack frame, while two grow by that amount).  Mostly because, when
iterating over the mask, gcc typically loads the value of cpu_xyz_mask
into a callee-saved register and from there into %rdi before each
find_next_bit call - now it can just load the appropriate immediate
address into %rdi before each call.

[1] See Rusty's kind explanation
http://thread.gmane.org/gmane.linux.kernel/2047078/focus=2047722 for
some historic context.

This patch (of 6):

As preparation for eliminating the indirect access to the various global
cpu_*_bits bitmaps via the pointer variables cpu_*_mask, rename the
cpu_online_mask member of struct fadump_crash_info_header to simply
online_mask, thus allowing cpu_online_mask to become a macro.

Stephen Boyd ef5c16b85b arch/frv/include/asm/io.h: accept const void pointers for read{b,w,l}() 
The SMD driver is reading and writing chunks of data to iomem, and
there's an __iowrite32_copy() function for the writing part, but no
__ioread32_copy() function for the reading part.  This series adds
__ioread32_copy() and uses it in two places.

This patch (of 4):

The frv port uses compiler builtins, __builtin_read*(), for the I/O read
routines.  Unfortunately, these don't accept const void pointers although
the generic ASM implementations do, so generic code passing const pointers
to these APIs cause compilers to emit warnings.  Add wrapper functions
that cast away the const to avoid the warnings.

Souvik Kumar Chakravarty 378f956e3f platform/x86: Add Intel Telemetry Core Driver 
Intel PM Telemetry is a software mechanism via which various SoC
PM and performance related parameters like PM counters, firmware
trace verbosity, the status of different devices inside the SoC, etc.
can be monitored and analyzed. The different samples that may be
monitored can be configured at runtime via exported APIs.

This patch adds the telemetry core driver that implements basic
exported APIs.
