      blink driver power saving · 0f4915b9
      Stephen Hemminger 提交于
      The blink driver wakes up every jiffies which wastes power unnecessarily.
      Using a notifier gives same effect. Also add ability to unload module.

        broken in many other ways too  -Linus ]

      i386: remove bogus mtrr range check · 4710bcce
      Linus Torvalds 提交于
      Commit 9215da33 "fixed" the MTRR range
      check to not allow any MTRR's under the 1MB mark (since that's where the
      fixed MTRR's are active).
      
      However, that was totally bogus, since it's normal (and almost required)
      to have a large variable MTRR that starts at 0, and covers some large
      percentage of the whole RAM, and then using the fixed MTRR's to override
      that large MTRR to handle the special ISA hole in the 640k-1M region.
      
      The old check was bogus too (checking that no variable MTRR is used that
      is entirely under the 1MB range), but at least it wasn't actively
      detrimental, because no sane situation would ever trigger such MTRR
      usage in the first place.
      
      That said, the whole notion of not allowing variable MTRR's in the low
      1MB is just stupid, so rather than revert the commit, this just removes
      the whole sad and unnecessary check entirely.
