-         Enabling this option will cause the kernel to distinguish between
-         ioremapped and physical addresses.  It will print a backtrace (at
-         most one every 10 seconds), hopefully allowing you to see which

-         for turning on USE_HPPA_IOREMAP.  The warnings are harmless;
-         the kernel has enough information to fix the broken drivers
-         automatically, but we'd like to make it more efficient by not
