      [CPUFREQ] SPEEDSTEP_RELAXED_CAP_CHECK option. · d9fa7b95
      Dave Jones authored
      A few SpeedStep-capable systems don't perform according to specification: the
      CPUID and/or some MSRs don't tell us the CPU is SpeedStep capable even though
      it definitely is. Allow a relaxed checking for one such issue by a module
      parameter only available if a config option is turned on. This is done to
      avoid the risk of doing invalid speedstep instructions on systems which do
      not support it, and which might even lead to (hardware) failure.

      [PATCH] fix up CPU detection in p4-clockmod · 7f6060e8
      Andrew Morton authored
      From: Dominik Brodowski <linux@dominikbrodowski.de>
      
      Too many users use the p4-clockmod cpufreq driver instead of the more
      advanced speedstep-centrino, speedstep-ich or even acpi drivers.  All of
      the latter (usually) provide voltage scaling, while the p4-clockmod driver
      only offers a variant of frequency scaling.  So, warn users if they try out
      this driver instead.
      
      Also, instead of using a local copy, use the speedstep_lib infrastructure
      for detecting the processor speed.  Adding the Pentium-M get_frequency
      function to that module only costs about 200 bytes in object size.

      [CPUFREQ] speedstep cleanups. · 91926815
      Dave Jones authored
      From Dominik Brodowski.
      
      - separate functions which might be useful for speedstep-piix4,
        speedstep-via or speedstep-bios into a new speedstep-lib.c.
      - clean up speedstep-ich as it will only be used for ICH-based chipsets
        in future.   
      - remove now-obsolete speedstep_coppermine parameter
