    Merge branch 'x86/mpx' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · c9cdd9a6
    Linus Torvalds authored
    Pull x86 cpufeature and mpx updates from Peter Anvin:
     "This includes the basic infrastructure for MPX (Memory Protection
      Extensions) support, but does not include MPX support itself.  It is,
      however, a prerequisite for KVM support for MPX, which I believe will
      be pushed later this merge window by the KVM team.
    
      This includes moving the functionality in
      futex_atomic_cmpxchg_inatomic() into a new function in uaccess.h so it
      can be reused - this will be used by the final MPX patches.
    
      The actual MPX functionality (map management and so on) will be pushed
      in a future merge window, when ready"
