      cpufreq: conservative: fix requested_freq reduction issue · 3baa976a
      Xiaoguang Chen authored
      When decreasing frequency, requested_freq may be less than
      freq_target, So requested_freq minus freq_target may be negative,
      But reqested_freq's unit is unsigned int, then the negative result
      will be one larger interger which may be even higher than
      requested_freq.
      
      This patch is to fix such issue. when result becomes negative,
      set requested_freq as the min value of policy.

      intel_pstate: skip the driver if ACPI has power mgmt option · fbbcdc07
      Adrian Huang authored
      Do not load the Intel pstate driver if the platform firmware
      (ACPI BIOS) supports the power management alternatives.
      The ACPI BIOS indicates that the OS control mode can be used
      if the _PSS (Performance Supported States) is defined in ACPI
      table. For the OS control mode, the Intel pstate driver will be
      loaded.
      
      HP BIOS has several power management modes (firmware, OS-control and
      so on). For the OS control mode in HP BIOS, the Intel p-state driver
      will be loaded. When the customer chooses the firmware power
      management in HP BIOS, the Intel p-state driver will be ignored.
      
      I put hw_vendor_info vendor_info in case other vendors (Dell, Lenovo...)
      have their firmware power management. Vendors should make sure their
      firmware power management works properly, and they can go for adding
      their vendor info to the variable.
      
      I have verified the patch on HP ProLiant servers.  The patch worked
      correctly.

      [rjw: Fixed up !CONFIG_ACPI build]
      [Linda Knippers: As Adrian has recently left HP, I retested the
      updated patch on an HP ProLiant server and verified that it is
      behaving correctly.  When the BIOS is configured for OS control for
      power management, the intel_pstate driver loads as expected.  When
      the BIOS is configured to provide the power management, the
      intel_pstate driver does not load and we get the pcc_cpufreq driver
      instead.]

      Pull ACPI and power management fixes from Rafael Wysocki:
      
       - intel_pstate fix for misbehavior after system resume if sysfs
         attributes are set in a specific way before the corresponding suspend
         from Dirk Brandewie.
      
       - A recent intel_pstate fix has no effect if unsigned long is 32-bit,
         so fix it up to cover that case as well.
      
       - The s3c64xx cpufreq driver was not updated when the index field of
         struct cpufreq_frequency_table was replaced with driver_data, so
         update it now.  From Charles Keepax.
      
       - The Kconfig help text for ACPI_BUTTON still refers to
         /proc/acpi/event that has been dropped recently, so modify it to
         remove that reference.  From Krzysztof Mazur.
      
       - A Lan Tianyu's change adds a missing mutex unlock to an error code
         path in acpi_resume_power_resources().
      
       - Some code related to ACPI power resources, whose very purpose is
         questionable to put it lightly, turns out to cause problems to happen
         during testing on real systems, so remove it completely (we may
         revisit that in the future if there's a compelling enough reason).
