      Don't know why to do the loop iteration here. It looks unneeded.

      [CPUFREQ] ARM Exynos4210 PM/Suspend compatibility with different bootloaders · 0073f538
      MyungJoo Ham authored
      We have various bootloaders for Exynos4210 machines. Some of they
      set the ARM core frequency at boot time even when the boot is a resume
      from suspend-to-RAM. Such changes may create inconsistency in the
      data of CPUFREQ driver and have incurred hang issues with suspend-to-RAM.
      
      This patch enables to save and restore CPU frequencies with pm-notifier and
      sets the frequency at the initial (boot-time) value so that there wouldn't
      be any inconsistency between bootloader and kernel. This patch does not
      use CPUFREQ's suspend/resume callbacks because they are syscore-ops, which
      do not allow to use mutex that is being used by regulators that are used by
      the target function.
      
      This also prevents any CPUFREQ transitions during suspend-resume context,
      which could be dangerous at noirq-context along with regulator framework.

      [CPUFREQ] ARM: ux500: send cpufreq notification for all cpus · 8efd072b
      Vincent Guittot authored
      The same clock is used for all cpus so we must notify the frequency change
      for each one in order to update the configuration of all twd clockevents.
      
      change since V1:
      * use policy->cpus instead of cpu_online_mask

      [CPUFREQ] e_powersaver: Allow user to lower maximum voltage · 826e570b
      Rafał Bilski authored
      Add new module option "set_max_voltage".
      One of the lessons learned from Adaptive Powersaver is that voltage values
      returned by processor are for worst case scenario. But required voltage
      is changing with CPU temperature. And even processors produced in the same
      batch can have different minimum voltage necessary for stable work at
      specified frequency.
      On Elonex Webbook, once system starts, temperature never drops below
      48 deg. C. Loading module after systems start allows user to lower CPU
      voltage and still have stable system.
      Sadly C7 doesn't allow code to set frequency or voltage from outside limits.
      If you ask it to set voltage lower then minimum it will ignore you. Thats
      why it isn't possible to change minimum voltage for minimum frequency too.
      Changing maximum voltage on Elonex Webbook leads to very good results. Looks
      like VIA C7 1.6GHz 1084mV can safetly run at 892mV. This means 83% of
      orginal value. If same percentage applies to power generated it means 12.5W
      in the place of 15W. Not much, but it is better then nothing.
      Only C7-M makes it possible.
      If voltage is too low by 16mV or more you will experience kernel panic.
      If voltage is too low by 32mV or more you will experience system freeze.

      [CPUFREQ] e_powersaver: Additional checks · ed361bf0
      Rafał Bilski authored
      Some systems are using 1,2Ghz@844mV processors running at 600MHz@796mV.
      Try to detect such systems and don't touch anything on it. If CPU doesn't have
      P-States in BIOS it should run at maximum frequency.
      Allow user to bypass checks by means of two new options.
      Don't set frequency to maximum on module unloading to avoid bada boom.
      It is also possible that some processors may have incorrect values in min/max
      registers caused by error in manufacturing process. Probably it would be BIOS
      job to set them to right frequency and P-States tables would have correct
      values inside.
      Two additional sanity checks for voltage.

      reader_lock has been turned into a raw lock by the core locking merge,
      and there was a new user of it introduced in this perf core merge.  Make

      params: make dashes and underscores in parameter names truly equal · b1e4d20c
      Michal Schmidt authored
      The user may use "foo-bar" for a kernel parameter defined as "foo_bar".
      Make sure it works the other way around too.
      
      Apply the equality of dashes and underscores on early_params and __setup
      params as well.
      
      The example given in Documentation/kernel-parameters.txt indicates that
      this is the intended behaviour.
      
      With the patch the kernel accepts "log-buf-len=1M" as expected.

      kmod: prevent kmod_loop_msg overflow in __request_module() · 37252db6
      Jiri Kosina authored
      Due to post-increment in condition of kmod_loop_msg in __request_module(),
      the system log can be spammed by much more than 5 instances of the 'runaway
      loop' message if the number of events triggering it makes the kmod_loop_msg
      to overflow.
      
      Fix that by making sure we never increment it past the threshold.

      md: Fix some bugs in recovery_disabled handling. · d890fa2b
      NeilBrown authored
      In 3.0 we changed the way recovery_disabled was handle so that instead
      of testing against zero, we test an mddev-> value against a conf->
      value.
      Two problems:
        1/ one place in raid1 was missed and still sets to '1'.
        2/ We didn't explicitly set the conf-> value at array creation
           time.
           It defaulted to '0' just like the mddev value does so they
           could appear equal and thus disable recovery.
           This did not affect normal 'md' as it calls bind_rdev_to_array
           which changes the mddev value.  However the dmraid interface
           doesn't call this and so doesn't change ->recovery_disabled; so at
           array start all recovery is incorrectly disabled.
      
      So initialise the 'conf' value to one less that the mddev value, so
      the will only be the same when explicitly set that way.
