I was looking at GDT updates in the Linux kernel and noticed some 
redundant code in initialization of the per-CPU GDT.  This code is no 
longer necessary or commented, so I removed it.   Basically, the code 
was trying to unbusy the TSS descriptor (which the set_tss_desc and 
__set_tss_desc functions already do by setting the descriptor type).  
This change saves only 20 bytes of space and makes the code more 
readable and maintainable.

Version: patched against 2.6.8.1-mm1
Testing: compile and boot a Linux 2.6 kernel with my patch.

Cheers,
