x86: cleanup - eliminate numbers in LDT allocation code
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
md5:
6cbec8705008ddb4b704aade60bceda3 ldt.o.before.asm
6cbec8705008ddb4b704aade60bceda3 ldt.o.after.asm
