60a9ce57e7 sched/cputime: Rename vtime fields
The current "snapshot" based naming on vtime fields suggests we record
some past event but that's a low level picture of their actual purpose
which comes out blurry. The real point of these fields is to run a basic
state machine that tracks down cputime entry while switching between
contexts.

So lets reflect that with more meaningful names.

cd0ae1d395 s390/crash: Remove unused KEXEC_NOTE_BYTES
After commmit 692f66f26a ("crash: move crashkernel parsing and vmcore
related code under CONFIG_CRASH_CORE") the KEXEC_NOTE_BYTES macro is not
used anymore and for s390 we create the ELF header in the new kernel
anyway. Therefore remove the macro.

a9ceea2674 Merge tag 'armsoc-dt64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM 64-bit DT updates from Arnd Bergmann:
 "Device-tree updates for arm64 platforms. For the first time I can
  remember, this is actually larger than the corresponding branch for
  32-bit platforms overall, though that has more individual changes.

  A significant portion this time is due to added machine support:

   - Initial support for the Realtek RTD1295 SoC, along with the Zidoo
     X9S set-top-box

   - Initial support for Actions Semi S900 and the Bubblegum-96
     single-board-cёmputer.

   - Rockchips support for the rk3399-Firefly single-board-computer gets
     added, this one stands out for being relatively fast, affordable
     and well₋supported, compared to many boards that only fall into one
     or two of the above categories.

   - Mediatek gains support for the mt6797 mobile-phone SoC platform and
     corresponding evaluation board.

   - Amlogic board support gets added for the NanoPi K2 and S905x
     LibreTech CC single-board computers and the R-Box Pro set-top-box

   - Allwinner board support gets added for the OrangePi Win, Orangepi
     Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single board computers
     and the SoPine system-on-module.

   - Renesas board support for Salvator-XS and H3ULCB automotive
     development systems.

   - Socionext Uniphier board support for LD11-global and LD20-global,
     whatever those may be.

   - Broadcom adds support for the new Stingray communication processor
     in its iProc family, along with two reference boards.

  Other updates include:

   - For the hisicon platform, support for Hi3660-Hikey960 gets extended
     significantly.

   - Lots of smaller updates for Renesas, Amlogic, Rockchip, UniPhier,
     Broadcom, Allwinner, Hisilicon, Qualcomm, Marvell, and NXP"

e854711291 Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Arnd Bergmann:
 "New SoC specific drivers:

   - NVIDIA Tegra PM Domain support for newer SoCs (Tegra186 and later)
     based on the "BPMP" firmware

   - Clocksource and system controller drivers for the newly added
     Action Semi platforms (both arm and arm64).

  Reset subsystem, merged through arm-soc by tradition:

   - New drivers for Altera Stratix10, TI Keystone and Cortina Gemini
     SoCs

   - Various subsystem-wide cleanups

  Updates for existing SoC-specific drivers

   - TI GPMC (General Purpose Memory Controller)

   - Mediatek "scpsys" system controller support for MT6797

   - Broadcom "brcmstb_gisb" bus arbitrer

   - ARM SCPI firmware

   - Renesas "SYSC" system controller

  One more driver update was submitted for the Freescale/NXP DPAA data
  path acceleration that has previously been used on PowerPC chips. I
  ended up postponing the merge until some API questions for its unusual
  MMIO access are resolved"

Pull ARM device-tree updates from Arnd Bergmann:
 "Device-tree continues to see lots of updates. The majority of patches
  here are smaller changes for new hardware on existing platforms, and
  there are a few larger changes worth pointing out.

  New machines:

   - The new Action Semi S500 platform is added along with initial
     support for the LeMaker Guitar board.

   - STM32 gains support for three new boards: stm32h743-disco,
     stm32f746-disco, and stm32f769-disco, along with new device support
     for the existing stm32f429 boards.

   - Renesas adds two new boards, the tiny GR-Peach based on RZ/A1H with
     10MB on-chip SRAM, and the iWave G20D-Q7 System-on-Module plus
     board.

   - On Marvell "mvebu", we gain support for the Linksys WRT3200ACM
     wireless router.

   - For NXP i.MX, we gain support for the Gateworks Ventana GW5600 and
     the Technexion Pico i.MX7D single-board computers.

   - The BeagleBone Blue is added for OMAP, it's the latest variation of
     the popular Beaglebone Black single-board computer.

   - The Allwinner based Lichee Pi Zero and NanoPi M1 Plus boards are
     added, these are the latest variations of a seemingly endless
     supply of similar single-board computers.

  Other updates:

   - Linus Walleij improves support for the "Faraday" based SoC
     platforms from various SoC makers (Moxart, Aspeed, Gemini)

   - The ARM Mali GPU is now describe on Rockchips SoCs

   - Mediatek MT7623 is extended significantly, making it much more
     useful.

   - Lots of individual updates on Renesas, OMAP, Rockchips, Broadcom,
     Allwinner, Qualcomm, iMX

   - For Amlogic, the clock support is extended a lot on meson8b.

   - We now build the devicetree file for the Raspberry Pi 3 on 32-bit
     ARM, in addition to the existing ARM64 support, to help users
     wanting to run a 32-bit system on it"

Pull ACPI updates from Rafael Wysocki:
 "These mostly update the ACPICA code in the kernel to upstream revision
  20170531 which covers all of the new material from ACPI 6.2, including
  new tables (WSMT, HMAT, PPTT), new subtables and definition changes
  for some existing tables (BGRT, HEST, SRAT, TPM2, PCCT), new resource

Pull power management updates from Rafael Wysocki:
 "The big ticket items here are the rework of suspend-to-idle in order
  to add proper support for power button wakeup from it on recent Dell
  laptops and the rework of interfaces exporting the current CPU
  frequency on x86.

  In addition to that, support for a few new pieces of hardware is
  added, the PCI/ACPI device wakeup infrastructure is simplified
  significantly and the wakeup IRQ framework is fixed to unbreak the IRQ
  bus locking infrastructure.

  Also, there are some functional improvements for intel_pstate, tools
  updates and small fixes and cleanups all over.

  Specifics:

   - Rework suspend-to-idle to allow it to take wakeup events signaled
     by the EC into account on ACPI-based platforms in order to properly
     support power button wakeup from suspend-to-idle on recent Dell
     laptops (Rafael Wysocki).

     That includes the core suspend-to-idle code rework, support for the
     Low Power S0 _DSM interface, and support for the ACPI INT0002
     Virtual GPIO device from Hans de Goede (required for USB keyboard
     wakeup from suspend-to-idle to work on some machines).

   - Stop trying to export the current CPU frequency via /proc/cpuinfo
     on x86 as that is inaccurate and confusing (Len Brown).

   - Rework the way in which the current CPU frequency is exported by
     the kernel (over the cpufreq sysfs interface) on x86 systems with
     the APERF and MPERF registers by always using values read from
     these registers, when available, to compute the current frequency
     regardless of which cpufreq driver is in use (Len Brown).

   - Rework the PCI/ACPI device wakeup infrastructure to remove the
     questionable and artificial distinction between "devices that can
     wake up the system from sleep states" and "devices that can
     generate wakeup signals in the working state" from it, which allows
     the code to be simplified quite a bit (Rafael Wysocki).

   - Fix the wakeup IRQ framework by making it use SRCU instead of RCU
     which doesn't allow sleeping in the read-side critical sections,
     but which in turn is expected to be allowed by the IRQ bus locking
     infrastructure (Thomas Gleixner).

   - Modify some computations in the intel_pstate driver to avoid
     rounding errors resulting from them (Srinivas Pandruvada).

   - Reduce the overhead of the intel_pstate driver in the HWP
     (hardware-managed P-states) mode and when the "performance" P-state
     selection algorithm is in use by making it avoid registering
     scheduler callbacks in those cases (Len Brown).

   - Rework the energy_performance_preference sysfs knob in intel_pstate
     by changing the values that correspond to different symbolic hint
     names used by it (Len Brown).

   - Make it possible to use more than one cpuidle driver at the same
     time on ARM (Daniel Lezcano).

   - Make it possible to prevent the cpuidle menu governor from using
     the 0 state by disabling it via sysfs (Nicholas Piggin).

   - Add support for FFH (Fixed Functional Hardware) MWAIT in ACPI C1 on
     AMD systems (Yazen Ghannam).

   - Make the CPPC cpufreq driver take the lowest nonlinear performance
     information into account (Prashanth Prakash).

   - Add support for hi3660 to the cpufreq-dt driver, fix the imx6q
     driver and clean up the sfi, exynos5440 and intel_pstate drivers
     (Colin Ian King, Krzysztof Kozlowski, Octavian Purdila, Rafael
     Wysocki, Tao Wang).

   - Fix a few minor issues in the generic power domains (genpd)
     framework and clean it up somewhat (Krzysztof Kozlowski, Mikko
     Perttunen, Viresh Kumar).

   - Fix a couple of minor issues in the operating performance points
     (OPP) framework and clean it up somewhat (Viresh Kumar).

   - Fix a CONFIG dependency in the hibernation core and clean it up
     slightly (Balbir Singh, Arvind Yadav, BaoJun Luo).

   - Add rk3228 support to the rockchip-io adaptive voltage scaling
     (AVS) driver (David Wu).

   - Fix an incorrect bit shift operation in the RAPL power capping
     driver (Adam Lessnau).

   - Add support for the EPP field in the HWP (hardware managed
     P-states) control register, HWP.EPP, to the x86_energy_perf_policy
     tool and update msr-index.h with HWP.EPP values (Len Brown).

   - Fix some minor issues in the turbostat tool (Len Brown).

   - Add support for AMD family 0x17 CPUs to the cpupower tool and fix a
     minor issue in it (Sherry Hurwitz).

   - Assorted cleanups, mostly related to the constification of some
     data structures (Arvind Yadav, Joe Perches, Kees Cook, Krzysztof
     Kozlowski)"

ad0af7104d vfs: introduce inode 'inuse' lock
Added an i_state flag I_INUSE and helpers to set/clear/test the bit.

The 'inuse' lock is an 'advisory' inode lock, that can be used to extend
exclusive create protection beyond parent->i_mutex lock among cooperating
users.

This is going to be used by overlayfs to get exclusive ownership on upper
and work dirs among overlayfs mounts.

2bece49394 ACPI: SPCR: Use access width to determine mmio usage
The current SPCR code does not check the access width of the MMIO, and
uses a default of 8bit register accesses.  This prevents devices that
only do 16 or 32bit register accesses from working.  By simply checking
this field and setting the MMIO string appropriately, this issue can be
corrected.  To prevent any legacy issues, the code will default to 8bit
accesses if the value is anything but 16 or 32.

9114014cf4 genirq: Add mutex to irq desc to serialize request/free_irq()
The irq_request/release_resources() callbacks ar currently invoked under
desc->lock with interrupts disabled. This is a source of problems on RT and
conceptually not required.

Add a seperate mutex to struct irq_desc which allows to serialize
request/free_irq(), which can be used to move the resource functions out of
the desc->lock held region.

0029c0deb5 net, ipv4: convert fib_info.fib_clntref from atomic_t to refcount_t
refcount_t type and corresponding API should be
used instead of atomic_t when the variable is used as
a reference counter. This allows to avoid accidental
refcounter overflows that might lead to use-after-free
situations.
