Merge tag 'pr-20141220-x86-vdso' of git://git./linux/kernel/git/luto/linux into x86/urgent

Pull a VDSO fix from Andy Lutomirski:

  "One vdso fix for a longstanding ASLR bug that's been in the news lately.

   The vdso base address has always been randomized, and I don't think there's
   anything particularly wrong with the range over which it's randomized,
   but the implementation seems to have been buggy since the very beginning.

   This fixes the implementation to remove a large bias that caused a small
   fraction of possible vdso load addresess to be vastly more likely than
   the rest of the possible addresses."
