      Pull power management and ACPI fixes from Rafael Wysocki:
       "Fixes for problems introduced or discovered recently (intel_pstate,
        sti-cpufreq, ARM64 cpuidle, Operating Performance Points framework,
        generic device properties framework) and one fix for a hotplug-related
        deadlock in ACPICA that's been there forever, but is nasty enough.
      
        Specifics:
      
         - Fix for a recent regression in the intel_pstate driver causing it
           to fail to restore the HWP (HW-managed P-states) configuration of
           the boot CPU after suspend-to-RAM (Rafael Wysocki).
      
         - Fix for two recent regressions in the intel_pstate driver, one that
           can trigger a divide by zero if the driver is accessed via sysfs
           before it manages to take the first sample and one causing it to
           fail to update a structure field used in a trace point, so the
           information coming from it is less useful (Rafael Wysocki).
      
         - Fix for a problem in the sti-cpufreq driver introduced during the
           4.5 cycle that causes it to break CPU PM in multi-platform kernels
           by registering cpufreq-dt (which subsequently doesn't work)
           unconditionally and preventing the driver that would actually work
           from registering (Sudeep Holla).
      
         - Stable-candidate fix for an ARM64 cpuidle issue causing idle state
           usage counters to be incorrectly updated for idle states that were
           not entered due to errors (James Morse).
      
         - Fix for a recently introduced issue in the OPP (Operating
           Performance Points) framework causing it to print bogus error
           messages for missing optional regulators (Viresh Kumar).
      
         - Fix for a recently introduced issue in the generic device
           properties framework that may cause it to attempt to dereferece and
           invalid pointer in some cases (Heikki Krogerus).
      
         - Fix for a deadlock in the ACPICA core that may be triggered by
           device (eg Thunderbolt) hotplug (Prarit Bhargava)"

      parisc: fix a bug when syscall number of tracee is __NR_Linux_syscalls · f0b22d1b
      Dmitry V. Levin authored
      Do not load one entry beyond the end of the syscall table when the
      syscall number of a traced process equals to __NR_Linux_syscalls.
      Similar bug with regular processes was fixed by commit 3bb457af
      ("[PARISC] Fix bug when syscall nr is __NR_Linux_syscalls").
      
      This bug was found by strace test suite.

      x86/tsc: Read all ratio bits from MSR_PLATFORM_INFO · 886123fb
      Chen Yu authored
      Currently we read the tsc radio: ratio = (MSR_PLATFORM_INFO >> 8) & 0x1f;
      
      Thus we get bit 8-12 of MSR_PLATFORM_INFO, however according to the SDM
      (35.5), the ratio bits are bit 8-15.
      
      Ignoring the upper bits can result in an incorrect tsc ratio, which causes the
      TSC calibration and the Local APIC timer frequency to be incorrect.
      
      Fix this problem by masking 0xff instead.

      Linus Torvalds authored
      Pull libnvdimm fixes from Dan Williams:
      
       - a fix for the persistent memory 'struct page' driver.  The
         implementation overlooked the fact that pages are allocated in 2MB
         units leading to -ENOMEM when establishing some configurations.
      
         It's tagged for -stable as the problem was introduced with the
         initial implementation in 4.5.
      
       - The new "error status translation" routine, introduced with the 4.6
         updates to the nfit driver, missed a necessary path in
         acpi_nfit_ctl().
      
         The end result is that we are falsely assuming commands complete
         successfully when the embedded status says otherwise.
