      Pull power management and ACPI material from Rafael J Wysocki:
       "These are fixes (operating performance points library, cpufreq-dt
        driver, cpufreq core, ACPI backlight, cpupower tool), cleanups
        (cpuidle), new processor IDs for the RAPL (Running Average Power
        Limit) power capping driver, and a modification of the generic power
        domains framework allowing modular drivers to call one of its helper
        functions.
      
        Specifics:
      
         - Fix for a potential NULL pointer dereference in the cpufreq core
           due to an initialization race condition (Ethan Zhao).
      
         - Fixes for abuse of the OPP (Operating Performance Points) API
           related to RCU and other minor issues in the OPP library and the
           cpufreq-dt driver (Dmitry Torokhov).
      
         - cpuidle governors cleanup making them measure idle duration in a
           better way without using the CPUIDLE_FLAG_TIME_INVALID flag which
           allows that flag to be dropped from the ACPI cpuidle driver and
           from the core too (Len Brown).
      
         - New ACPI backlight blacklist entries for Samsung machines without a
           working native backlight interface that need to use the ACPI
           backlight instead (Aaron Lu).
      
         - New CPU IDs of future Intel Xeon CPUs for the Intel RAPL power
           capping driver (Jacob Pan).
      
         - Generic power domains framework modification to export the
           of_genpd_get_from_provider() function to modular drivers that will
           allow future driver modifications to be based on the mainline (Amit
           Daniel Kachhap).

           Bhargava)"

      Pull thermal management updates from Zhang Rui:
       "First of all, the most important change is the thermal cpu cooling
        fixes.  The major fix here is to have proper sequencing between
        cpufreq layer and thermal cpu cooling registration.  A take away of
        this fix is an improvement in the thermal drivers code.  Thermal
        drivers that require cpu cooling do not need to check for cpufreq
        layer.  The requirement now is to propagate the error code, if any,
        while registering cpu cooling device.  Thanks to Viresh for
        implementing the required CPUfreq changes.
      
        Second, a new driver is introduced for int340x processor thermal
        device.  Given that int340x thermal is disabled by default, and this
        processor thermal device is only available on limited platforms, plus
        the driver does nothing but exposes some thermal limitation
        information for user space to use, thus I think it is safe to include
        it in this pull request after missing 3.19-rc2.
      
        Specifics:
      
         - Thermal cpu cooling fixes and cleanups.
      
         - introduce INT340X processor thermal reporting device driver.

      mm: get rid of radix tree gfp mask for pagecache_get_page · 45f87de5
      Michal Hocko authored
      Commit 2457aec6 ("mm: non-atomically mark page accessed during page
      cache allocation where possible") has added a separate parameter for
      specifying gfp mask for radix tree allocations.
      
      Not only this is less than optimal from the API point of view because it
      is error prone, it is also buggy currently because
      grab_cache_page_write_begin is using GFP_KERNEL for radix tree and if
      fgp_flags doesn't contain FGP_NOFS (mostly controlled by fs by
      AOP_FLAG_NOFS flag) but the mapping_gfp_mask has __GFP_FS cleared then
      the radix tree allocation wouldn't obey the restriction and might
      recurse into filesystem and cause deadlocks.  This is the case for most
      filesystems unfortunately because only ext4 and gfs2 are using
      AOP_FLAG_NOFS.
      
      Let's simply remove radix_gfp_mask parameter because the allocation
      context is same for both page cache and for the radix tree.  Just make
      sure that the radix tree gets only the sane subset of the mask (e.g.  do
      not pass __GFP_WRITE).
      
      Long term it is more preferable to convert remaining users of
      AOP_FLAG_NOFS to use mapping_gfp_mask instead and simplify this
      interface even further.

      parisc: fix out-of-register compiler error in ldcw inline assembler function · 45db0738
      John David Anglin authored
      The __ldcw macro has a problem when its argument needs to be reloaded from
      memory. The output memory operand and the input register operand both need to
      be reloaded using a register in class R1_REGS when generating 64-bit code.
      This fails because there's only a single register in the class. Instead, use a
      memory clobber. This also makes the __ldcw macro a compiler memory barrier.

      ALSA: hda_intel: apply the Seperate stream_tag for Skylake · d6795827
      Libin Yang authored
      The total stream number of Skylake's input and output stream
      exceeds 15, which will cause some streams do not work because
      of the overflow on SDxCTL.STRM field if using the legacy
      stream tag allocation method.
      
      This patch uses the new stream tag allocation method by add
      the flag AZX_DCAPS_SEPARATE_STREAM_TAG for Skylake platform.

      ALSA: hda_controller: Separate stream_tag for input and output streams. · 93e3423e
      Rafal Redzimski authored
      Implemented separate stream_tag assignment for input and output streams.
      According to hda specification stream tag must be unique throughout the
      input streams group, however an output stream might use a stream tag
      which is already in use by an input stream. This change is necessary
      to support HW which provides a total of more than 15 stream DMA engines
      which with legacy implementation causes an overflow on SDxCTL.STRM
      field (and the whole SDxCTL register) and as a result usage of
      Reserved value 0 in the SDxCTL.STRM field which confuses HDA controller.

      audit: restore AUDIT_LOGINUID unset ABI · 041d7b98
      Richard Guy Briggs authored
      A regression was caused by commit 780a7654:
      	 audit: Make testing for a valid loginuid explicit.
      (which in turn attempted to fix a regression caused by e1760bd5)
      
      When audit_krule_to_data() fills in the rules to get a listing, there was a
      missing clause to convert back from AUDIT_LOGINUID_SET to AUDIT_LOGINUID.
      
      This broke userspace by not returning the same information that was sent and
      expected.
      
      The rule:
      	auditctl -a exit,never -F auid=-1
      gives:
      	auditctl -l
      		LIST_RULES: exit,never f24=0 syscall=all
      when it should give:
      		LIST_RULES: exit,never auid=-1 (0xffffffff) syscall=all
      
      Tag it so that it is reported the same way it was set.  Create a new
      private flags audit_krule field (pflags) to store it that won't interact with
      the public one from the API.
