      Pull power management fixes from Rafael Wysocki:
       "These fix two PCI power management regressions from the 4.13 cycle and
        one cpufreq schedutil governor bug introduced during the 4.12 cycle,
        drop a stale comment from the schedutil code and fix two mistakes in
        docs.
      
        Specifics:
      
         - Restore device_may_wakeup() check in pci_enable_wake() removed
           inadvertently during the 4.13 cycle to prevent systems from drawing
           excessive power when suspended or off, among other things (Rafael
           Wysocki).
      
         - Fix pci_dev_run_wake() to properly handle devices that only can
           signal PME# when in the D3cold power state (Kai Heng Feng).
      
         - Fix the schedutil cpufreq governor to avoid using UINT_MAX as the
           new CPU frequency in some cases due to a missing check (Rafael
           Wysocki).
      
         - Remove a stale comment regarding worker kthreads from the schedutil
           cpufreq governor (Juri Lelli).
      
         - Fix a copy-paste mistake in the intel_pstate driver documentation
           (Juri Lelli).
      
         - Fix a typo in the system sleep states documentation (Jonathan
           Neuschäfer)"

       "nouveau, amdgpu, i915, vc4, omap, exynos and atomic fixes.
      
        As last week seemed a bit slow, we got a few more fixes this week.
      
        The main stuff is two weeks of fixes for amdgpu, some missing bits of
        vega12 atom firmware support were added, and some power management
        fixes.
      
        Nouveau got two regression fixes for an DP MST deadlock and a random
        oops fix.
      
        i915 got an LVDS panel timeout fix 2 WARN fixes.
      
        exynos fixed a pagefault issue in the mixer driver.
      
        vc4 has an oops fix.
      
        omap had a bunch of uninit var and error-checking fixes. Two atomic

      PCI / PM: Check device_may_wakeup() in pci_enable_wake() · cfcadfaa
      Rafael J. Wysocki 提交于
      Commit 0847684c (PCI / PM: Simplify device wakeup settings code)
      went too far and dropped the device_may_wakeup() check from
      pci_enable_wake() which causes wakeup to be enabled during system
      suspend, hibernation or shutdown for some PCI devices that are not
      allowed by user space to wake up the system from sleep (or power off).
      
      As a result of this, excessive power is drawn by some of the affected
      systems while in sleep states or off.
      
      Restore the device_may_wakeup() check in pci_enable_wake(), but make
      sure that the PCI bus type's runtime suspend callback will not call
      device_may_wakeup() which is about system wakeup from sleep and not
      about device wakeup from runtime suspend.

      drm/ttm: Use GFP_TRANSHUGE_LIGHT for allocating huge pages · da291320
      Michel Dänzer 提交于
      GFP_TRANSHUGE tries very hard to allocate huge pages, which can result
      in long delays with high memory pressure. I have observed firefox
      freezing for up to around a minute due to this while restic was taking
      a full system backup.
      
      Since we don't really need huge pages, use GFP_TRANSHUGE_LIGHT |
      __GFP_NORETRY instead, in order to fail quickly when there are no huge
      pages available.
      
      Set __GFP_KSWAPD_RECLAIM as well, in order for huge pages to be freed
      up in the background if necessary.
      
      With these changes, I'm no longer seeing freezes during a restic backup.
