       "There are only three patches this time, most other changes to files in
        include/asm-generic tend to go through the tree of whoever depends on
        the change.
      
        Two patches are cleanups for stuff that is no longer needed, the main
        change is to adapt the generic version of BUG_ON() for CONFIG_BUG=n to
        make it behave consistently with BUG().
      
        This avoids undefined behavior along with a number of warnings about
        that undefined behavior in randconfig builds when we keep going on
        after hitting a BUG_ON()"

      Linus Torvalds authored
      Pull more power management and ACPI updates from Rafael Wysocki:
       "The second batch of power management and ACPI updates for v4.6.
      
        Included are fixups on top of the previous PM/ACPI pull request and
        other material that didn't make into it but still should go into 4.6.
      
        Among other things, there's a fix for an intel_pstate driver issue
        uncovered by recent cpufreq changes, a workaround for a boot hang on
        Skylake-H related to the handling of deep C-states by the platform and
        a PCI/ACPI fix for the handling of IO port resources on non-x86
        architectures plus some new device IDs and similar.
      
        Specifics:
      
         - Fix for an intel_pstate driver issue related to the handling of MSR
           updates uncovered by the recent cpufreq rework (Rafael Wysocki).
      
         - cpufreq core cleanups related to starting governors and frequency
           synchronization during resume from system suspend and a locking fix
           for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).
      
         - acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
           Michael Neuling, Richard Cochran, Shilpasri Bhat).
      
         - intel_idle driver update preventing some Skylake-H systems from
           hanging during initialization by disabling deep C-states mishandled
           by the platform in the problematic configurations (Len Brown).
      
         - Intel Xeon Phi Processor x200 support for intel_idle
           (Dasaratharaman Chandramouli).
      
         - cpuidle menu governor updates to make it always honor PM QoS
           latency constraints (and prevent C1 from being used as the fallback
           C-state on x86 when they are set below its exit latency) and to
           restore the previous behavior to fall back to C1 if the next timer
           event is set far enough in the future that was changed in 4.4 which
           led to an energy consumption regression (Rik van Riel, Rafael
           Wysocki).
      
         - New device ID for a future AMD UART controller in the ACPI driver
           for AMD SoCs (Wang Hongcheng).
      
         - Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
           scaling (AVS) driver (David Wu).
      
         - ACPI PCI resources management fix for the handling of IO space
           resources on architectures where the IO space is memory mapped
           (IA64 and ARM64) broken by the introduction of common ACPI
           resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).
      
         - Fix for the ACPI backend of the generic device properties API to
           make it parse non-device (data node only) children of an ACPI
           device correctly (Irina Tirdea).
      
         - Fixes for the handling of global suspend flags (introduced in 4.4)
           during hibernation and resume from it (Lukas Wunner).
      
         - Support for obtaining configuration information from Device Trees
           in the PM clocks framework (Jon Hunter).
      
         - ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
           King, Geert Uytterhoeven)"

         - The i.MX changes were sent relatively late, and had a dependency on
           the clk tree, so I delayed that a bit.  Support for the new i.MX6qp
           SoC and a couple of new boards is added in this branch.
      
         - Uniphier renames a few files to match the final product names that
           were decided by the company, kudos to the kernel developer(s) for
           getting support upstream before the product release.  Also two
           boards are added.  The patches were posted early enough and nice
           overall, but we forgot to apply them and decided to give it some

      Handle the Oscillator Failure ('OF') bit from Oscillator Status register
      (0x1D). This bit is cleared on set_time function and is read each time the
      date/time is read, but only in case of XT Oscillator selection.
      In RC mode, this bit is always set.

      Mylène Josserand authored
      
      
      The autocalibration is separated in two bits to set in Oscillator
      Control register (0x1c) :
       - OSEL bit to select the oscillator type (XT or RC).
       - ACAL bit to select the autocalibration type.
      
      These functionnalities are exported in sysfs entries : "oscillator"
      and "autocalibration". Respectively, the values are "xtal" for XT
      oscillator and "rc" for RC oscillator and 0 to disable the
      autocalibration cycle, 512 for a 512 seconds autocalibration cycle
      and 1024 for a cycle of 1024 seconds.
      
      Examples :
      Set to XT Oscillator
      echo xtal > /sys/class/rtc/rtc0/device/oscillator
      Activate an autocalibration every 512 seconds
      echo 512 > /sys/class/rtc/rtc0/device/autocalibration

      Alexandre Belloni authored
      
      
      The rv8803 has a 60µs window where it will not answer on the i2c bus.
      It also means there will be no ack for the communication. Make sure
      communication is tried multiple times when this happens (the i2c subsystem
      mandates -ENXIO is that case but the number of retries is host specific).
      The critical parts are the probe function and the alarm callback so make
      sure we handle the failure there.

      Pull thermal updates from Zhang Rui:
      
       - Fix a regression where bogus trip points on some Lenovo laptops start
         to screw up thermal control after commit 81ad4276 ("Thermal:
         initialize thermal zone device correctly").
      
         On these Lenovo laptops, a bogus passive trip point is reported,
         which is 0 degree Celsius.  Without commit 81ad4276, thermal zone
         fails to set cooling devices to proper cooling state, which is a bug.
         But with commit 81ad4276 applied, the processors are always
         throttled on these Lenovo laptops because the current temperature is
         always higher than the passive trip point.
      
         Fix things to ignore such bogus trip points.  (Zhang Rui)
      
       - Introduce Mediatek thermal driver.  (Sascha Hauer)
      
       - Introduce devm_ versions of OF thermal sensor register API.  (Laxman

      arm64: mm: allow preemption in copy_to_user_page · 691b1e2e
      Mark Rutland authored
      
      
      Currently we disable preemption in copy_to_user_page; a behaviour that
      we inherited from the 32-bit arm code. This was necessary for older
      cores without broadcast data cache maintenance, and ensured that cache
      lines were dirtied and cleaned by the same CPU. On these systems dirty
      cache line migration was not possible, so this was sufficient to
      guarantee coherency.
      
      On contemporary systems, cache coherence protocols permit (dirty) cache
      lines to migrate between CPUs as a result of speculation, prefetching,
      and other behaviours. To account for this, in ARMv8 data cache
      maintenance operations are broadcast and affect all data caches in the
      domain associated with the VA (i.e. ISH for kernel and user mappings).
      
      In __switch_to we ensure that tasks can be safely migrated in the middle
      of a maintenance sequence, using a dsb(ish) to ensure prior explicit
      memory accesses are observed and cache maintenance operations are
      completed before a task can be run on another CPU.
      
      Given the above, it is not necessary to disable preemption in
      copy_to_user_page. This patch removes the preempt_{disable,enable}
      calls, permitting preemption.

      arm64: consistently use p?d_set_huge · c661cb1c
      Mark Rutland authored
      Commit 324420bf
      
       ("arm64: add support for ioremap() block
      mappings") added new p?d_set_huge functions which do the hard work to
      generate and set a correct block entry.
      
      These differ from open-coded huge page creation in the early page table
      code by explicitly setting the P?D_TYPE_SECT bits (which are implicitly
      retained by mk_sect_prot() for any valid prot), but are otherwise
      identical (and cannot fail on arm64).
      
      For simplicity and consistency, make use of these in the initial page
      table creation code.

      arm64: kaslr: use callee saved register to preserve SCTLR across C call · d5e57437
      Ard Biesheuvel authored
      
      
      The KASLR code incorrectly expects the contents of x18 to be preserved
      across a call into C code, and uses it to stash the contents of SCTLR_EL1
      before enabling the MMU. If the MMU needs to be disabled again to create
      the randomized kernel mapping, x18 is written back to SCTLR_EL1, which is
      likely to crash the system if x18 has been clobbered by kasan_early_init()
      or kaslr_early_init(). So use x22 instead, which is not in use so far in
      head.S
