      cpufreq: governor: Get rid of governor events · e788892b
      Rafael J. Wysocki 提交于
      The design of the cpufreq governor API is not very straightforward,
      as struct cpufreq_governor provides only one callback to be invoked
      from different code paths for different purposes.  The purpose it is
      invoked for is determined by its second "event" argument, causing it
      to act as a "callback multiplexer" of sorts.
      
      Unfortunately, that leads to extra complexity in governors, some of
      which implement the ->governor() callback as a switch statement
      that simply checks the event argument and invokes a separate function
      to handle that specific event.
      
      That extra complexity can be eliminated by replacing the all-purpose
      ->governor() callback with a family of callbacks to carry out specific
      governor operations: initialization and exit, start and stop and policy
      limits updates.  That also turns out to reduce the code size too, so
      do it.

      Eliminate bad hash multipliers from hash_32() and hash_64() · ef703f49
      George Spelvin 提交于
      The "simplified" prime multipliers made very bad hash functions, so get rid
      of them.  This completes the work of 689de1d6.
      
      To avoid the inefficiency which was the motivation for the "simplified"
      multipliers, hash_64() on 32-bit systems is changed to use a different
      algorithm.  It makes two calls to hash_32() instead.
      
      drivers/media/usb/dvb-usb-v2/af9015.c uses the old GOLDEN_RATIO_PRIME_32
      for some horrible reason, so it inherits a copy of the old definition.
