Bug description:
  The do_double_fault function in arch/x86/kernel/traps.c in the Linux
  kernel through 3.17.4 does not properly handle faults associated with
  the Stack Segment (SS) segment register, which allows local users to
  cause a denial of service (panic) via a modify_ldt system call, as
  demonstrated by sigreturn_32 in the linux-clock-tests test suite.

  Break-Fix: - 6f442be2fb22be02cafa606f1769fa1e6f894441
