• a5c9161f2   x86, atomic64: In selftest, distinguish x86-64 from 586+ ... Browse Code »

  The x86-64 implementation of the atomics is totally different from the
  i586+ implementation, which makes it quite confusing to call it
  "586+". Also fix indentation, and add "i" for "i386" and "i586" as
  used elsewhere in the kernel.
