Can you try this patch for this one?

For these, try backing out the user-desc patch.  You may one of those 
primitive beings who lacks a modify_ldt_t in your asm/ldt.h.

 	That patch helped.

 	Actually I don't need to revert this one; after reverting the 
compile fails.  Leaving it in works.  The compile finishes.
 	Thanks again for your help, Jeff and Blaisor.
 	Cheers,
