Huang Ying cb9f753a37 mm: fix races between swapoff and flush dcache 
Thanks to commit 4b3ef9daa4 ("mm/swap: split swap cache into 64MB
trunks"), after swapoff the address_space associated with the swap
device will be freed.  So page_mapping() users which may touch the
address_space need some kind of mechanism to prevent the address_space
from being freed during accessing.

The dcache flushing functions (flush_dcache_page(), etc) in architecture
specific code may access the address_space of swap device for anonymous
pages in swap cache via page_mapping() function.  But in some cases
there are no mechanisms to prevent the swap device from being swapoff,
for example,

  CPU1					CPU2
  __get_user_pages()			swapoff()
    flush_dcache_page()
      mapping = page_mapping()
        ...				  exit_swap_address_space()
        ...				    kvfree(spaces)
        mapping_mapped(mapping)

The address space may be accessed after being freed.

But from cachetlb.txt and Russell King, flush_dcache_page() only care
about file cache pages, for anonymous pages, flush_anon_page() should be
used.  The implementation of flush_dcache_page() in all architectures
follows this too.  They will check whether page_mapping() is NULL and
whether mapping_mapped() is true to determine whether to flush the
dcache immediately.  And they will use interval tree (mapping->i_mmap)
to find all user space mappings.  While mapping_mapped() and
mapping->i_mmap isn't used by anonymous pages in swap cache at all.

So, to fix the race between swapoff and flush dcache, __page_mapping()
is add to return the address_space for file cache pages and NULL
otherwise.  All page_mapping() invoking in flush dcache functions are
replaced with page_mapping_file().

Huacai Chen 7bbaf27d9c zboot: fix stack protector in compressed boot phase 
Calling __stack_chk_guard_setup() in decompress_kernel() is too late
that stack checking always fails for decompress_kernel() itself.  So
remove __stack_chk_guard_setup() and initialize __stack_chk_guard before
we call decompress_kernel().

Original code comes from ARM but also used for MIPS and SH, so fix them
together.  If without this fix, compressed booting of these archs will
fail because stack checking is enabled by default (>=4.16).

Linus Torvalds 167569343f ARM: SoC platform updates for 4.17 
This release brings up a new platform based on the old ARM9 core: the
 Nuvoton NPCM is used as a baseboard management controller, competing
 with the better known ASpeed AST2xx series.
 
 Another important change is the addition of ARMv7-A based chips
 in mach-stm32. The older parts in this platform are ARMv7-M based
 microcontrollers, now they are expanding to general-purpose workloads.
 
 The other changes are the usual defconfig updates to enable additional
 drivers, lesser bugfixes. The largest updates as often are the ongoing
 OMAP cleanups, but we also have a number of changes for the older
 PXA and davinci platforms this time.
 
 For the Renesas shmobile/r-car platform, some new infrastructure
 is needed to make the watchdog work correctly.
 
 Supporting Multiprocessing on Allwinner A80 required a significant
 amount of new code, but is not doing anything unexpected.

Linus Torvalds b240b419db ARM: SoC device tree updates for 4.17 
This is the usual set of changes for device trees, with over 700
 non-merged changesets. There is an ongoing set of dtc warning fixes and
 the usual bugfixes, cleanups and added device support.
 
 The most interesting bit as usual is support for new machines listed
 below:
 
 - The Allwinner H6 makes its debut with the Pine-H64 board, and we get
   two new machines based on its older siblings: the H5 based OrangePi
   Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side,
   we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2
   Zero development board (based on H2).
 
 - NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
   development board and p2888 CPU module.
 
 - The Nuvoton npcm750 is a BMC that was newly added, for now we only
   support running on the evaluation board.
 
 - STmicroelectronics stm32 gains support for the stm32mp157c and two
   evaluation boards.
 
 - The Toradex Colibri board family grows a few members based on the
   i.MX6ULL variant.
 
 - The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6
   family of chips.
 
 - The Phytec phyBOARD Mira is a family of industrial boards based on
   i.MX6. For now, four models get added.
 
 - TI am335x based PDU-001 is an industrial embedded machine used for
   traffic monitoring
 
 - The Aspeed platform now supports running on the BMC on the Qualcomm
   Centriq 2400 server
 
 - Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm
   msm8974 based Galaxy S5 is a rather different phone made by the same
   company.
 
 - The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file
   for the various boards made by Xilinx themselves, as well as the
   Digilent Zybo Z7.
 
 - The ARM Versatile family now supports the "IB2" interface board.
 
 - The Renesas H2 based "Stout" and the H3 based Salvator-X are more
   evaluation boards named after a kind of beer, as most of them are.
   The r8a77980 (V3H) based "Condor" apparently doesn't follow that
   tradition. ;-)
 
 - ROC-RK3328-CC is a simple developement board from the Libre Computer
   Project, based on the Rockchips RK3328 SoC
 
 - Haiku is another development board plus Qseven module based on Rockchips
   RK3368 and made by Theobroma Systems.

Russell King 5f8d561fb0 ARM: decompressor: fix warning introduced in fortify patch 
Commit ee333554fe ("ARM: 8749/1: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE")
introduced a new warning:

arch/arm/boot/compressed/misc.c: In function 'fortify_panic':
arch/arm/boot/compressed/misc.c:167:1: error: 'noreturn' function does return [-Werror]

The simple solution would be to make 'error' a noreturn function, but
this causes a prototype mismatch as the function is prototyped in
several .c files.  So, move the function prototype to a new header.

There are also a couple of variables that are also declared in several
locations.  Clean this up while we are here.

Linus Torvalds df34df483a Staging/IIO patches for 4.17-rc1 
Here is the big set of Staging/IIO driver patches for 4.17-rc1.
 
 It is a lot, over 500 changes, but not huge by previous kernel release
 standards.  We deleted more lines than we added again (27k added vs. 91k
 remvoed), thanks to finally being able to delete the IRDA drivers and
 networking code.
 
 We also deleted the ccree crypto driver, but that's coming back in
 through the crypto tree to you, in a much cleaned-up form.
 
 Added this round is at lot of "mt7621" device support, which is for an
 embedded device that Neil Brown cares about, and of course a handful of
 new IIO drivers as well.
 
 And finally, the fsl-mc core code moved out of the staging tree to the
 "real" part of the kernel, which is nice to see happen as well.
 
 Full details are in the shortlog, which has all of the tiny cleanup
 patches described.
 
 All of these have been in linux-next for a while with no reported
 issues.

Linus Torvalds 642e7fd233 Merge branch 'syscalls-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux 
Pull removal of in-kernel calls to syscalls from Dominik Brodowski:
 "System calls are interaction points between userspace and the kernel.
  Therefore, system call functions such as sys_xyzzy() or
  compat_sys_xyzzy() should only be called from userspace via the
  syscall table, but not from elsewhere in the kernel.

  At least on 64-bit x86, it will likely be a hard requirement from
  v4.17 onwards to not call system call functions in the kernel: It is
  better to use use a different calling convention for system calls
  there, where struct pt_regs is decoded on-the-fly in a syscall wrapper
  which then hands processing over to the actual syscall function. This
  means that only those parameters which are actually needed for a
  specific syscall are passed on during syscall entry, instead of
  filling in six CPU registers with random user space content all the
  time (which may cause serious trouble down the call chain). Those
  x86-specific patches will be pushed through the x86 tree in the near
  future.

  Moreover, rules on how data may be accessed may differ between kernel
  data and user data. This is another reason why calling sys_xyzzy() is
  generally a bad idea, and -- at most -- acceptable in arch-specific
  code.

  This patchset removes all in-kernel calls to syscall functions in the
  kernel with the exception of arch/. On top of this, it cleans up the
  three places where many syscalls are referenced or prototyped, namely
  kernel/sys_ni.c, include/linux/syscalls.h and include/linux/compat.h"

Dominik Brodowski 9d5b7c956b mm: add ksys_fadvise64_64() helper; remove in-kernel call to sys_fadvise64_64() 
Using the ksys_fadvise64_64() helper allows us to avoid the in-kernel
calls to the sys_fadvise64_64() syscall. The ksys_ prefix denotes that
this function is meant as a drop-in replacement for the syscall. In
particular, it uses the same calling convention as ksys_fadvise64_64().

Some compat stubs called sys_fadvise64(), which then just passed through
the arguments to sys_fadvise64_64(). Get rid of this indirection, and call
ksys_fadvise64_64() directly.

This patch is part of a series which removes in-kernel calls to syscalls.
On this basis, the syscall entry path can be streamlined. For details, see

Pull perf updates from Ingo Molnar:
 "The main kernel side changes were:

   - Modernize the kprobe and uprobe creation/destruction tooling ABIs:

     The existing text based APIs (kprobe_events and uprobe_events in

     to clean up after themselves, which is both difficult and fragile
     if the tool is buggy or exits unexpectedly. In other words they are
     not really suited for modern, robust tooling.

     So introduce a modern, file descriptor based ABI that does not have
     these limitations: introduce the 'perf_kprobe' and 'perf_uprobe'

     a kprobe/uprobe attached to them. These [k,u]probe are associated
     with this file descriptor, so they are not available in tracefs.

     (Song Liu)

   - Intel Cannon Lake CPU support (Harry Pan)

   - Intel PT cleanups (Alexander Shishkin)

   - Improve the performance of pinned/flexible event groups by using RB
     trees (Alexey Budankov)

   - Add PERF_EVENT_IOC_MODIFY_ATTRIBUTES which allows the modification
     of hardware breakpoints, which new ABI variant massively speeds up
     existing tooling that uses hardware breakpoints to instrument (and
     debug) memory usage.

     (Milind Chabbi, Jiri Olsa)

   - Various Intel PEBS handling fixes and improvements, and other Intel
     PMU improvements (Kan Liang)

   - Various perf core improvements and optimizations (Peter Zijlstra)

   - ... misc cleanups, fixes and updates.

  There's over 200 tooling commits, here's an (imperfect) list of
  highlights:

   - 'perf annotate' improvements:

      * Recognize and handle jumps to other functions as calls, which
        improves the navigation along jumps and back. (Arnaldo Carvalho
        de Melo)

      * Add the 'P' hotkey in TUI annotation to dump annotation output
        into a file, to ease e-mail reporting of annotation details.
        (Arnaldo Carvalho de Melo)

      * Add an IPC/cycles column to the TUI (Jin Yao)

      * Improve s390 assembly annotation (Thomas Richter)

      * Refactor the output formatting logic to better separate it into
        interactive and non-interactive features and add the --stdio2
        output variant to demonstrate this. (Arnaldo Carvalho de Melo)

   - 'perf script' improvements:

      * Add Python 3 support (Jaroslav Škarvada)

      * Add --show-round-event (Jiri Olsa)

   - 'perf c2c' improvements:

      * Add NUMA analysis support (Jiri Olsa)

   - 'perf trace' improvements:

      * Improve PowerPC support (Ravi Bangoria)

   - 'perf inject' improvements:

      * Integrate ARM CoreSight traces (Robert Walker)

   - 'perf stat' improvements:

      * Add the --interval-count option (yuzhoujian)

      * Add the --timeout option (yuzhoujian)

   - 'perf sched' improvements (Changbin Du)

   - Vendor events improvements :

      * Add IBM s390 vendor events (Thomas Richter)

      * Add and improve arm64 vendor events (John Garry, Ganapatrao
        Kulkarni)

      * Update POWER9 vendor events (Sukadev Bhattiprolu)

   - Intel PT tooling improvements (Adrian Hunter)

   - PMU handling improvements (Agustin Vega-Frias)

   - Record machine topology in perf.data (Jiri Olsa)

   - Various overwrite related cleanups (Kan Liang)

   - Add arm64 dwarf post unwind support (Kim Phillips, Jean Pihet)

   - ... and lots of other changes, cleanups and fixes, see the shortlog
     and Git history for details"

David Lechner f6adc9fd1f ARM: davinci: da8xx: simplify CFGCHIP regmap_config 
Since commit 8253bb3f82 ("regmap: potentially duplicate the name
string stored in regmap"), the name field of struct regmap_config
is copied in __regmap_init(), so we no longer need to worry about
keeping our own copy of the name.

Just use a string literal in the initialization of da8xx_cfgchip_config
instead of creating a separate variable for the name.

This fixes a possible kernel oops due to using stack allocated platform
data for the USB PHY driver on DA8XX devices. If the platform device
probe is deferred, then we get a corrupt pointer for the platform data.

We now use a global static struct for the platform data so that the
platform data pointer does not get written over.

Arnd Bergmann 59162c9366 Renesas ARM Based SoC Updates for v4.17 
01d675f159 ARM: shmobile: rcar-gen2: Add watchdog support
 58adf1ba0d ARM: shmobile: Add watchdog support
 
 * SoC
   - Identify R-Car V3H (r8a77980) and M3N (r8a77965)
 
   - Enable R-Car Gen2 regulator quirk for Stout board with H3 (r8a7790) SoC
 
     Marek Vaust says "Regulator setup is suboptimal on H2 Stout too. The
     Stout newly has two DA9210 regulators, so the quirk is extended to
     handle another DA9210 at i2c address 0x70."
 
   - Add watchdog support
 
     This is the SoC portion of the following solution. It is not yet
     enabled in DT as it is not functional without clock dependencies
     in place.
 
     Fabrizio Castro says "this series has been around for some time as RFC,
     and it has collected useful comments from the community along the way.
     The solution proposed by this patch set works for most R-Car Gen2 and
     RZ/G1 devices, but not all of them. We now know that for some R-Car
     Gen2 early revisions there is no proper software fix. Anyway, no
     product has been built around early revisions, but development boards
     mounting early revisions (basically prototypes) are still out there.
     As a result, this series isn't enabling the internal watchdog on R-Car
     Gen2 boards, developers may enable it in board specific device trees if
     needed.  This series has been tested by me on the iwg20d, iwg22d,
     Lager, Alt, and Koelsch boards.
 
    The problem
    ===========
    To deal with SMP on R-Car Gen2 and RZ/G1, we install a reset vector to
    ICRAM1 and we program the [S]BAR registers so that when we turn ON the
    non-boot CPUs they are redirected to the reset vector installed by Linux
    in ICRAM1, and eventually they continue the execution to RAM, where the
    SMP bring-up code will take care of the rest.  The content of the [S]BAR
    registers survives a watchdog triggered reset, and as such after the
    watchdog fires the boot core will try and execute the SMP bring-up code
    instead of jumping to the bootrom code.
 
    The fix
    =======
    The main strategy for the solution is to let the reset vector decide if
    it needs to jump to shmobile_boot_fn or to the bootrom code.  In a
    watchdog triggered reset scenario, since the [S]BAR registers keep their
    values, the boot CPU will jump into the newly designed reset vector, the
    assembly routine will eventually test WOVF (a bit in register RWTCSRA
    that indicates if the watchdog counter has overflown, the value of this
    bit gets retained in this scenario), and jump to the bootrom code which
    will in turn load up the bootloader, etc.  When bringing up SMP or using
    CPU hotplug, the reset vector will jump to shmobile_boot_fn instead."
 
 * R-Car Rst
   - Add support for R-Car V3H (r8a77980) and V3H (r8a77980)
 
 * R-Car SYSC
   - Mark rcar_sysc_matches[] __initconst
 
    Geert Uytterhoeven says "This frees another 1764 bytes
    (arm32/shmobile_defconfig) or 1000 bytes (arm64/renesas_defconfig) of
    memory after kernel init."
 
   - Fix power area parents
 
     Sergei Shtylyov says "According to the figure 9.2(b) of the R-Car
     Series, 3rd Generation User’s Manual: Hardware Rev. 0.80 the A2IRn and
     A2SCn power areas in R8A77970 have the A3IR area as a parent, thus the
     SYSC driver has those parents wrong.."

Arnd Bergmann 8045f29754 Defconfig updates for omap variants for v4.17 merge window 
We need to enable MMC_SDHCI option in both omap2plus_defconfig and
 multi_v7_defconfig so systems are able to mount root when the dts files
 get updated for sdhci.
 
 Then let's update omap2plus_defconfig so we can patch it easier. And as
 Arnd noticed earlier, just running make savedefconfig will accidentally
 drop few Kconfig options. This is happening because some options are no
 longer available as loadable modules like LIRC. Or new dependencies have
 been added such as SND_OSSEMUL for selecting SOUND_OSS_CORE.
 
 So we first move the unchanged options around to their make savedefconfig
 suggested place, then update the options to prevent make savedefconfig
 dropping some options accidentally, and then finally drop the unused
 options.
 
 And after that we enable options DRM_OMAP and 8250_OMAP. These both have
 been around for years now. And we do have 8250_OMAP warn about console
 being redirected with SERIAL_8250_OMAP_TTYO_FIXUP option that is enabled
 by default. Some users may need to update their inittab to use ttyS*
 instead of ttyO* though. If this turns out to be a problem, we may want
 to introduce a separate compatible for 8250-omap. But I think we're good
 to go with the SERIAL_8250_OMAP_TTYO_FIXUP warning now. Let's not update
 multi_v7_defconfig yet though and first see how 8250_OMAP change plays
 out.
 
 We also enable few new options for PM on am335x and am437x, and CEC in
 omap2plus_defconfig. Naturally similar options can be later on added to
 multi_v7_defconfig, but in this series we only enable OTG, MUSB and the
 related PHYs in multi_v7_defconfig to make it more usable for distros.

Arnd Bergmann 18b6843f96 ARM: imx: fix imx6sll-only build 
When selecting SOC_IMX6SLL but not SOC_IMX6SL, we get a link error:

arch/arm/mach-imx/mach-imx6sl.o: In function `imx6sl_init_late':
mach-imx6sl.c:(.init.text+0x14): undefined reference to `imx6sl_cpuidle_init'

This adds the missing line to the Makefile to also build the cpuidle
support that we need here.

Arnd Bergmann da395584b8 ARM: imx: select ARM_CPU_SUSPEND for CPU_IDLE as well 
The cpuidle support calls cpu_suspend(), which is compiled conditionally,
and fails to link unless something selects CONFIG_ARM_CPU_SUSPEND.

arch/arm/mach-imx/cpuidle-imx6sx.o: In function `imx6sx_enter_wait':

Hauke Mehrtens aab9581a7d ARM: dts: armada-385-linksys: Disable internal RTC 
The internal RTC does not work correctly on these Linksys boards based
on Marvell SoCs. For me it only shows Wed Dec 31 23:59:59 1969 and for
others it is off by 3 minutes in 10 minutes running, this was reported
by multiple users. On the Linksys Mamba device the device tree comment
says that no crystal is connected to the internal RTC, this is probably
also true for the other devices.

Arnd Bergmann cdcdbbf350 Renesas ARM Based SoC DT Updates for v4.17 
* Silk board with R-Car E2 (r8a7794) SoC
   - Add r1ex24002 EEPROM to DT
 
     Magnus Damm says "Extend the Silk board support to include U14 which is
     an I2C based EEPROM hooked up to the I2C1 bus."
 
   - Add GPIO keys to DT
 
     Magnus Damm says "Extend the Silk board support to include SW3, SW4,
     SW6 and SW12. They are all connected via GPIO lines and handled by the
     gpio-keys driver"
 
 * Marzen board with R-Car H1 (r7a7779) SoC
   - Add SDHI0 VCCQ Regulator
 
     Magnus Damm says "Add support for the on-board voltage regulator hooked
     up to GPIO3_20 on r8a7779 Marzen. The board schematics describes the
     regulator as U4 TPS2110A. Input wise, U4 has D0 fixed to ground, D1
     tied to GPIO3_20 while IN1 is fixed to 3.3V and IN2 is fixed to 1.8V.
     OUT goes to the pull-ups for the data pins of SDHI0."
 
 * Porter board with R-Car M3W (r8a7791) SoC
   - Fix HDMI output routing
 
     Laurent Pinchart says "The HDMI encoder is connected to the RGB output
     of the DU, which is port@0, not port@1."
 
 * iWave Systems RZ/G1E SODIMM System On Module (iW-RainboW-G22M-SM) and
   iWave Systems RZ/G1M Qseven System On Module (iW-RainboW-G20M-Qseven)
   - Enable cmt0
 
 * Stout board with R-Car H2 (r8a7790) SoC
   - Initial support
 
 * Lager board with R-Car H2 (r8a7790) SoC
   - Add CEC clock for HDMI transmitter
 
     Niklas Söderlund says "The adv7511 on the Lager board has a 12 MHz
     fixed clock for the CEC block. Specify this in the dts to enable CEC
     support."
 
   - Move cec_clock to root node
 
     By definition nodes without a bus address do not belong on the bus
 
 * kzm9d board with EMMA Mobile EV2 (EMEV2) SoC
   - Fix "debounce-interval" property misspelling
 
 * RZ/G1M (r8a7743) and RZ/G1H (r8a7745) SoCs
   - Add IPMMU DT nodes
   - Add VSP support
 
 * R-Car Gen2 boards
   - Use I2C demuxer for
 
     This allows run-time switching between alternate I2C IP blocks
 
 * R-Car Gen2 and RZ/G1 SoCs
   - Clean up DT files to ease future maintenance
     + add soc node for IP attached to the bus
     + sort subnodes of soc and root node
     + consistently use single space after =
 
 * R-Car H2 (r8a7790), M3-W (r8a7791) and M3-N (r7a7793) SoCs
   - Reduce size of thermal registers
 
     According to the "User's Manual: Hardware" v2.00 the registers at base
     0xe61f0000 extend to an offset of 0x10, rather than 0x14 which is the
     case on the r8a73a4 (R-Mobile APE6).
 
     This should not have any runtime affect as mapping granularity is
     PAGE_SIZE.

Arnd Bergmann 66f3731f39 Two fixes for omap variants for v4.16-rc cycle 
Fix insecure W+X mapping warning for SRAM for omaps that
 don't yet use drivers/misc/*sram*.c code. An earlier attempt
 at fixing this turned out to cause problems with PM on omap3,
 this version works with PM on omap3.
 
 Also fix dmtimer probe for omap16xx devices that was noticed
 with the pending dmtimer move to drivers. It seems this has
 been broken for a while and is a non-critical for booting.
 It is needed for PM on omap16xx though.

Re-sync the defconfig by doing:

make savedefconfig
cp defconfig arch/arm/configs/mxs_defconfig

So keep it in sync to help further changes in defconfig.

The explanation for removing the Kconfig symbols:

CONFIG_FHANDLE=y: verified that it is still selected
selected
CONFIG_DEVPTS_MULTIPLE_INSTANCES=y: does not exist anymore
CONFIG_NVMEM=y: verified that it is still selected
CONFIG_LOCKUP_DETECTOR=y: need to select CONFIG_SOFTLOCKUP_DETECTOR now
CONFIG_TIMER_STATS=y: does not exist anymore

Boot tested on a imx28evk.

Michael Forney a670b0b4ae kbuild: Use ls(1) instead of stat(1) to obtain file size 
stat(1) is not standardized and different implementations have their own
(conflicting) flags for querying the size of a file.

ls(1) provides the same information (value of st.st_size) in the 5th
column, except when the file is a character or block device. This output
is standardized[0]. The -n option turns on -l, which writes lines
formatted like

  "%s %u %s %s %u %s %s\n", <file mode>, <number of links>,
      <owner name>, <group name>, <size>, <date and time>,
      <pathname>

but instead of writing the <owner name> and <group name>, it writes the
numeric owner and group IDs (this avoids /etc/passwd and /etc/group
lookups as well as potential field splitting issues).

The <size> field is specified as "the value that would be returned for
the file in the st_size field of struct stat".

To avoid duplicating logic in several locations in the tree, create
scripts/file-size.sh and update callers to use that instead of stat(1).

Jinbum Park 73b9160d0d ARM: 8748/1: mm: Define vdso_start, vdso_end as array 
Define vdso_start, vdso_end as array to avoid compile-time analysis error
for the case of built with CONFIG_FORTIFY_SOURCE.

and, since vdso_start, vdso_end are used in vdso.c only,
move extern-declaration from vdso.h to vdso.c.

If kernel is built with CONFIG_FORTIFY_SOURCE,
compile-time error happens at this code.
- if (memcmp(&vdso_start, "177ELF", 4))

The size of "&vdso_start" is recognized as 1 byte, but n is 4,
So that compile-time error is reported.
