-         Enabling this option will cause the kernel to distinguish between
-         ioremapped and physical addresses.  It will print a backtrace (at

-         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.
          If you don't debug the kernel, you can say N, but we may not be able
