Is there any particular reason why there cannot just be a PGT_descr_page, combining the two currently existing types?
Even if it's only a page, I'd want to avoid wasting memory for nothing, and i386's default_ldt could easily move into
the same page cpu_gdt_table lives in. Alternatively one could also use empty_zero_page here. Or do it like on x86-64,
where the symbol doesn't exist at all, and knowledge about it being all zeroes is used where needed. Jan
