re: mm/mpol: Make MPOL_LOCAL a real policy

[Dan Carpenter]

Hello Peter Zijlstra,

The patch 03ed7b538ca0: "mm/mpol: Make MPOL_LOCAL a real policy" from 
Mar 19, 2012, leads to the following warning:
mm/mempolicy.c:2591 mpol_parse_str()
	 error: buffer overflow 'policy_modes' 5 <= 5

mm/mempolicy.c
  2590          for (mode = 0; mode < MPOL_MAX; mode++) {
  2591                  if (!strcmp(str, policy_modes[mode])) {
  2592                          break;
  2593                  }
  2594          }

The problem is that MPOL_NOOP is not defined in policy_modes[] so we
search past the end of the array.

regards,
dan carpenter
