Pull "Nuke 386-DX/SX support" from Ingo Molnar:
 "This tree removes ancient-386-CPUs support and thus zaps quite a bit
  of complexity:

    24 files changed, 56 insertions(+), 425 deletions(-)

  ... which complexity has plagued us with extra work whenever we wanted
  to change SMP primitives, for years.

  Unfortunately there's a nostalgic cost: your old original 386 DX33
  system from early 1991 won't be able to boot modern Linux kernels
  anymore.  Sniff."

I'm not sentimental.  Good riddance.
