2d2474a194 Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal managament updates from Zhang Rui:

 - Enhance thermal "userspace" governor to export the reason when a
   thermal event is triggered and delivered to user space. From Srinivas
   Pandruvada

 - Introduce a single TSENS thermal driver for the different versions of
   the TSENS IP that exist, on different qcom msm/apq SoCs'. Support for
   msm8916, msm8960, msm8974 and msm8996 families is also added. From
   Rajendra Nayak

 - Introduce hardware-tracked trip points support to the device tree
   thermal sensor framework. The framework supports an arbitrary number
   of trip points. Whenever the current temperature is changed, the trip
   points immediately below and above the current temperature are found,
   driver callback is invoked to program the hardware to get notified
   when either of the two trip points are triggered. Hardware-tracked
   trip points support for rockchip thermal driver is also added at the
   same time. From Sascha Hauer, Caesar Wang

 - Introduce a new thermal driver, which enables TMU (Thermal Monitor
   Unit) on QorIQ platform. From Jia Hongtao

 - Introduce a new thermal driver for Maxim MAX77620. From Laxman
   Dewangan

 - Introduce a new thermal driver for Intel platforms using WhiskeyCove
   PMIC. From Bin Gao

 - Add mt2701 chip support to MTK thermal driver. From Dawei Chien

 - Enhance Tegra thermal driver to enable soctherm node and set
   "critical", "hot" trips, for Tegra124, Tegra132, Tegra210. From Wei
   Ni

 - Add resume support for tango thermal driver. From Marc Gonzalez

 - several small fixes and improvements for rockchip, qcom, imx, rcar,
   mtk thermal drivers and thermal core code. From Caesar Wang, Keerthy,
   Rocky Hao, Wei Yongjun, Peter Robinson, Bui Duc Phuc, Axel Lin, Hugh
   Kang

Kernel source files need not include <linux/kconfig.h> explicitly
because the top Makefile forces to include it with:

  -include $(srctree)/include/linux/kconfig.h

This commit removes explicit includes except the following:

  * arch/s390/include/asm/facilities_src.h
  * tools/testing/radix-tree/linux/kernel.h

These two are used for host programs.

3989144f86 kthread: kthread worker API cleanup
A good practice is to prefix the names of functions by the name
of the subsystem.

The kthread worker API is a mix of classic kthreads and workqueues.  Each
worker has a dedicated kthread.  It runs a generic function that process
queued works.  It is implemented as part of the kthread subsystem.

This patch renames the existing kthread worker API to use
the corresponding name from the workqueues API prefixed by
kthread_:

__init_kthread_worker()		-> __kthread_init_worker()
init_kthread_worker()		-> kthread_init_worker()
init_kthread_work()		-> kthread_init_work()
insert_kthread_work()		-> kthread_insert_work()
queue_kthread_work()		-> kthread_queue_work()
flush_kthread_work()		-> kthread_flush_work()
flush_kthread_worker()		-> kthread_flush_worker()

Note that the names of DEFINE_KTHREAD_WORK*() macros stay
as they are. It is common that the "DEFINE_" prefix has
precedence over the subsystem names.

Note that INIT() macros and init() functions use different
naming scheme. There is no good solution. There are several
reasons for this solution:

  + "init" in the function names stands for the verb "initialize"
    aka "initialize worker". While "INIT" in the macro names
    stands for the noun "INITIALIZER" aka "worker initializer".

  + INIT() macros are used only in DEFINE() macros

  + init() functions are used close to the other kthread()
    functions. It looks much better if all the functions
    use the same scheme.

  + There will be also kthread_destroy_worker() that will
    be used close to kthread_cancel_work(). It is related
    to the init() function. Again it looks better if all
    functions use the same naming scheme.

  + there are several precedents for such init() function
    names, e.g. amd_iommu_init_device(), free_area_init_node(),
    jump_label_init_type(),  regmap_init_mmio_clk(),

  + It is not an argument but it was inconsistent even before.

54c721b857 mips/panic: replace smp_send_stop() with kdump friendly version in panic path
Daniel Walker reported problems which happens when
crash_kexec_post_notifiers kernel option is enabled
(https://lkml.org/lkml/2015/6/24/44).

In that case, smp_send_stop() is called before entering kdump routines
which assume other CPUs are still online.  As the result, kdump
routines fail to save other CPUs' registers.  Additionally for MIPS
OCTEON, it misses to stop the watchdog timer.

To fix this problem, call a new kdump friendly function,
crash_smp_send_stop(), instead of the smp_send_stop() when
crash_kexec_post_notifiers is enabled.  crash_smp_send_stop() is a
weak function, and it just call smp_send_stop().  Architecture
codes should override it so that kdump can work appropriately.
This patch provides MIPS version.

0ee59413c9 x86/panic: replace smp_send_stop() with kdump friendly version in panic path
Daniel Walker reported problems which happens when
crash_kexec_post_notifiers kernel option is enabled
(https://lkml.org/lkml/2015/6/24/44).

In that case, smp_send_stop() is called before entering kdump routines
which assume other CPUs are still online.  As the result, for x86, kdump
routines fail to save other CPUs' registers and disable virtualization
extensions.

To fix this problem, call a new kdump friendly function,
crash_smp_send_stop(), instead of the smp_send_stop() when
crash_kexec_post_notifiers is enabled.  crash_smp_send_stop() is a weak
function, and it just call smp_send_stop().  Architecture codes should
override it so that kdump can work appropriately.  This patch only
provides x86-specific version.

For Xen's PV kernel, just keep the current behavior.

NOTES:

- Right solution would be to place crash_smp_send_stop() before
  __crash_kexec() invocation in all cases and remove smp_send_stop(), but
  we can't do that until all architectures implement own
  crash_smp_send_stop()

- crash_smp_send_stop()-like work is still needed by
  machine_crash_shutdown() because crash_kexec() can be called without
  entering panic()

05c2679e95 unicore32: use simpler API for random address requests
Currently, all callers to randomize_range() set the length to 0 and
calculate end by adding a constant to the start address.  We can simplify
the API to remove a bunch of needless checks and variables.

Use the new randomize_addr(start, range) call to set the requested

f8850abb7b parisc: Fix kernel memory layout regarding position of __gp
Architecturally we need to keep __gp below 0x1000000.

But because of ftrace and tracepoint support, the RO_DATA_SECTION now gets much
bigger than it was before. By moving the linkage tables before RO_DATA_SECTION
we can avoid that __gp gets positioned at a too high address.

Due to the additional support of ftrace, tracepoint and huge pages the kernel

d4b05923f5 x86/pkeys: Make protection keys an "eager" feature
Our XSAVE features are divided into two categories: those that
generate FPU exceptions, and those that do not.  MPX and pkeys do
not generate FPU exceptions and thus can not be used lazily.  We
disable them when lazy mode is forced on.

We have a pair of masks to collect these two sets of features, but
XFEATURE_MASK_PKRU was added to the wrong mask: XFEATURE_MASK_LAZY.
Fix it by moving the feature to XFEATURE_MASK_EAGER.

Note: this only causes problem if you boot with lazy FPU mode
(eagerfpu=off) which is *not* the default.  It also only affects
hardware which is not currently publicly available.  It looks like
eager mode is going away, but we still need this patch applied
to any kernel that has protection keys and lazy mode, which is 4.6
through 4.8 at this point, and 4.9 if the lazy removal isn't sent
to Linus for 4.9.

df610d6788 x86/apic: Prevent pointless warning messages
Markus reported that he sees new warnings:

  APIC: NR_CPUS/possible_cpus limit of 4 reached.  Processor 4/0x84 ignored.
  APIC: NR_CPUS/possible_cpus limit of 4 reached.  Processor 5/0x85 ignored.

This comes from the recent persistant cpuid - nodeid changes. The code
which emits the warning has been called prior to these changes only for
enabled processors. Now it's called for disabled processors as well to get
the possible cpu accounting correct. So if the kernel is compiled for the
number of actual available/enabled CPUs and the BIOS reports disabled CPUs
as well then the above warnings are printed.

That's a pointless exercise as it only makes sense if there are more CPUs
enabled than the kernel supports.

Nake the warning conditional on enabled processors so we are back to the
state before these changes.

f3bf1dbe64 x86/acpi: Prevent LAPIC id 0xff from being accounted
Yinghai reported that the recent changes to make the cpuid - nodeid
relationship permanent causes a cpuid ordering regression on a system which
has 2apic enabled..

The reason is that the ACPI local APIC parser has no sanity check for
apicid 0xff, which is an invalid id. So a CPU id for this invalid local
APIC id is allocated and therefor breaks the cpuid ordering.

Add a sanity check to acpi_parse_lapic() which ignores the invalid id.

c913fc4146 ARM: SoC: late DT updates for v4.9
These updates have been kept in a separate branch mostly because
 they rely on updates to the respective clk drivers to keep the
 shared header files in sync.
 
 - The Renesas r8a7796 (R-Car M3-W) platform gets added, this is an
   automotive SoC similar to the ⅹ8a7795 chip we already support, but
   the dts changes rely on a clock driver change that has been
   merged for v4.9 through the clk tree.
 
 - The Amlogic meson-gxbb (S905) platform gains support for a few
   drivers merged through our tree, in particular the network and
   usb driver changes are required and included here, and also
   the clk tree changes.
 
 - The Allwinner platforms have seen a large-scale change to their
   clk drivers and the dts file updates must come after that.
   This includes the newly added Nextthing GR8 platform, which is
   derived from sun5i/A13.
 
 - Some integrator (arm32) changes rely on clk driver changes.
 
 - A single patch for lpc32xx has no such dependency but wasn't
   added until just before the merge window

6afd563d4b ARM: SoC driver updates for v4.9
Driver updates for ARM SoCs, including a couple of newly added drivers:
 
 - The Qualcomm external bus interface 2 (EBI2), used in some of their
   mobile phone chips for connecting flash memory, LCD displays or
   other peripherals
 
 - Secure monitor firmware for Amlogic SoCs, and an NVMEM driver for the
   EFUSE based on that firmware interface.
 
 - Perf support for the AppliedMicro X-Gene performance monitor unit
 
 - Reset driver for STMicroelectronics STM32
 
 - Reset driver for SocioNext UniPhier SoCs
 
 Aside from these, there are minor updates to SoC-specific bus,
 clocksource, firmware, pinctrl, reset, rtc and pmic drivers.

b4f33f6ddd ARM: SoC 64-bit changes for v4.9
Changes to platform code for 64-bit ARM platforms.
 
 Nearly all of these are defconfig updates to enable new drivers or old
 drivers still used on these 64-bit platforms.
 
 Aside from that, we gain initial support for two set-top-box platforms,
 both of which already have 32-bit support in arch/arm:
 
 - Broadcom adds abstract support for the bcm7xxx/brcmstb platform,
   presumably the respective dts files and more information will
   follow at a later point.
 
 - The ZTE ZX296718 SoC for set-top-boxes, a relative of the 32-bit
   ZX296702 SoC that we already support.

66f2c6d952 ARM: SoC platform updates for v4.9
These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - We get support for running in big-endian mode on two platforms:
   sunxi (Allwinner) and s3c24xx (old Samsung).
 
 - The recently added Uniphier platform now uses standard PSCI
   methods for SMP booting and we remove support for old bootloader
   versions that did not support it yet.
 
 - In sunxi, we gain support for the "Nextthing GR8" SoC, which
   is a close relative of the Allwinner A13 and R8 chips.
 
 - PXA completes its move over to the generic dmaengine framework
   and removes its old private API
 
 - mach-bcm gains support for BCM47189/BCM53573, their first ARM
   SoC with integrated 802.11ac wireless networking.

a771151a83 ARM: SoC cleanups for v4.9
The cleanups for v4.9 are a little larger that usual, but thankfully
 that is almost exclusively due to removing a significant number of
 files that have become obsolete after the still ongoing conversion
 of old board files to devicetree.
 
 - for mach-omap2, which is still the largest platform in arch/arm/,
   the conversion to DT is finally complete after the Nokia N900 is
   now fully supported there, along with the omap3 LDP, and we can
   remove those two board files.
   If no regressions are found, another large cleanup for the platform
   will happen as a follow-up, removing dead code and restructuring
   the platform based on being DT-only.
 
 - In mach-imx, similar work is ongoing, but has not come that far.
   This time, we remove the obsolete board file for the i.MX1
   generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now DT-only.
   The remaining board files are for i.MX2 and i.MX3 machines
   based on old ARM926 or ARM1136 cores that should work with DT
   in principle.
 
 - realview has just been converted from board files to DT, and a lot
   of code gets removed in the process. This is the last
   ARM/Keil/Versatile derived platform that was still using board
   files, the other ones being integrator, versatile and vexpress.
   We can probably merge the remaining code into a single directory
   in the near future.
 
 - clps711x had completed the conversion in v4.8, but we accidentally
   left the files in place that should have been deleted then.
 
 Conflicts: two files deleted here have been modified upstream,
 the changes can be discarded.

   - Fix boot of 32bit SMP kernel (initial kernel mapping was too small)

   - Added hardened usercopy checks

   - Drop bootmem and switch to memblock and NO_BOOTMEM implementation

   - Drop the BROKEN_RODATA config option (and thus remove the relevant
     code from the generic headers and files because parisc was the last
     architecture which used this config option)

   - Improve segfault reporting by printing human readable error strings

   - Various smaller changes, e.g. dwarf debug support for assembly
     code, update comments regarding copy_user_page_asm, switch to
     kmalloc_array()"

* 'parisc-4.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
  parisc: Increase KERNEL_INITIAL_SIZE for 32-bit SMP kernels
  parisc: Drop bootmem and switch to memblock
  parisc: Add hardened usercopy feature
  parisc: Add cfi_startproc and cfi_endproc to assembly code
  parisc: Move hpmc stack into page aligned bss section
  parisc: Fix self-detected CPU stall warnings on Mako machines
  parisc: Report trap type as human readable string
  parisc: Update comment regarding implementation of copy_user_page_asm
