Please apply. Fix should also be headed for stable tree and backported,
it is really sadly trivial. Glauber, Ingo, sorry for the offlist
posting, somehow the original missed LKML.

For a few seconds I thought it was diff going mad diff'ing exactly
similar lines.
This one could actually use some capitalization to reduce the
possibility of similar problems in future - rename to write_IDT_entry
and write_LDT_entry perhaps?
