    Merge branch 'x86-mpx-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · 3eb5b893
    Linus Torvalds authored
    Pull x86 MPX support from Thomas Gleixner:
     "This enables support for x86 MPX.
      MPX is a new debug feature for bound checking in user space.  It
      requires kernel support to handle the bound tables and decode the
      bound violating instruction in the trap handler"
