      hwmon: (w83627ehf) Fix number of fans for NCT6776F · 585c0fd8
      Guenter Roeck 提交于
      NCT6776F can select fan input pins for fans 3 to 5 with a secondary set of
      chip register bits. Check that second set of bits in addition to the first set
      to detect if fans 3..5 are monitored.

      Power management fixes for 3.3-rc3
      
      Three power management regression fixes, one for a recent regression introcuded
      by the freezer changes during the 3.3 merge window and two for regressions
      in cpuidle (resulting from PM QoS changes) and in the hibernate user space
      interface, both introduced during the 3.2 development cycle.
      
      They include:
      
      * Two hibernate (s2disk) regression fixes from Srivatsa S. Bhat (for
       regressions introduced during the 3.3 merge window and during the 3.2
       development cycle).
      
      * A cpuidle fix from Venki Pallipadi for a regression resulting from PM QoS
       changes during the 3.2 development cycle causing cpuidle to work incorrectly
       for CONFIG_PM unset.

      PM / QoS: CPU C-state breakage with PM Qos change · d020283d
      Venkatesh Pallipadi 提交于
      Looks like change "PM QoS: Move and rename the implementation files"
      merged during the 3.2 development cycle made PM QoS depend on
      CONFIG_PM which depends on (PM_SLEEP || PM_RUNTIME).
      
      That breaks CPU C-states with kernels not having these CONFIGs, causing CPUs
      to spend time in Polling loop idle instead of going into deep C-states,
      consuming way way more power. This is with either acpi idle or intel idle
      enabled.
      
      Either CONFIG_PM should be enabled with any pm_qos users or
      the !CONFIG_PM pm_qos_request() should return sane defaults not to break
      the existing users. Here's is the patch for the latter option.
      
      [rjw: Modified the changelog slightly.]

      PM / Freezer: Thaw only kernel threads if freezing of kernel threads fails · 379e0be8
      Srivatsa S. Bhat 提交于
      If freezing of kernel threads fails, we are expected to automatically
      thaw tasks in the error recovery path. However, at times, we encounter
      situations in which we would like the automatic error recovery path
      to thaw only the kernel threads, because we want to be able to do
      some more cleanup before we thaw userspace. Something like:
      
      error = freeze_kernel_threads();
      if (error) {
      	/* Do some cleanup */
      
      	/* Only then thaw userspace tasks*/
      	thaw_processes();
      }
      
      An example of such a situation is where we freeze/thaw filesystems
      during suspend/hibernation. There, if freezing of kernel threads
      fails, we would like to thaw the frozen filesystems before thawing
      the userspace tasks.
      
      So, modify freeze_kernel_threads() to thaw only kernel threads in
      case of freezing failure. And change suspend_freeze_processes()
      accordingly. (At the same time, let us also get rid of the rather
      cryptic usage of the conditional operator (:?) in that function.)
      
      [rjw: In fact, this patch fixes a regression introduced during the
       3.3 merge window, because without it thaw_processes() may be called
       before swsusp_free() in some situations and that may lead to massive
       memory allocation failures.]
