Browse source 
This patch eliminates numbers in LDT allocation code
trying to make it clear to understand from where
these numbers come.

No code changed:

   text    data     bss     dec     hex filename
   1896       0       0    1896     768 ldt.o.before
   1896       0       0    1896     768 ldt.o.after
