Description from Michael Kerrisk. He suggested an identical patch to one I had already coded up and tested. commit fe3d197f "x86, mpx: On-demand kernel allocation of bounds tables" added two new prctl() operations, PR_MPX_ENABLE_MANAGEMENT and PR_MPX_DISABLE_MANAGEMENT. However, no checks were included to ensure that unused arguments are zero, as is done in many existing prctl()s and as should be done for all new prctl()s. This patch adds the required checks.
