• 2d040a1ce   x86/mm: New tunable for single vs full TLB flush ... Browse Code »

  Most of the logic here is in the documentation file. Please take
  a look at it.

  I know we've come full-circle here back to a tunable, but this
  new one is *WAY* simpler. I challenge anyone to describe in one
  sentence how the old one worked. Here's the way the new one
  works:

  If we are flushing more pages than the ceiling, we use
  the full flush, otherwise we use per-page flushes.
