          allocation as well as poisoning memory on free to catch use of freed

-         Enabling this option will cause the kernel to distinguish between

-         for turning on USE_HPPA_IOREMAP.  The warnings are harmless;
-         the kernel has enough information to fix the broken drivers

          If you say Y here the resulting kernel image will be slightly larger
          but not slower, and it will give very useful debugging information.
