It sure is, but let me also register for the record that I hate the
bloody bitfield. A lot of what the bitfield does is completely
pointless (breaking down the type field, which really is nothing other
than a magic constant as far as the kernel is anyway) and generates
insanely bad code.

I honestly think if we used macros like GDT_ENTRY() and perhaps a few
variants we would make the code simpler.
