455           Overriding LED state on ThinkPads can mask important

458           the bay while buses are still active), etc.
460           LED control on the ThinkPad is write-only (with very few
461           exceptions on very ancient models), which makes it
462           impossible to know beforehand if important information will
463           be lost when one changes LED state.

893          This module will allow you the enter and exit PRTM in the BIOS via
894          sysfs on platforms that support this feature.  System in PRTM will
895          not receive CPU-generated SMIs for recoverable errors.  Use of this
896          feature without proper support may void your hardware warranty.
898          If the proper BIOS support is found the driver will load and create
899          /sys/devices/system/ibm_rtl/.  The "state" variable will indicate
900          whether or not the BIOS is in PRTM.
