Remove undocumented hack.
--
Switch to the temporary stack right away when booted via multiboot. GRUB
happens to give a correct stack, but it is not guaranteed by the spec. This
temporary stack will be reset later, which is fine.
Fixes PR/50245.
--
Pfff, use %ss and not %ds. The latter is controlled by userland, the former
contains the kernel value (flat); FreeBSD fixed this too a few weeks ago.
As I said earlier, this dtrace code is complete bullshit.
--
Don't allow userland to create 286/386 call gates anymore - they are not
used by Wine. While here, don't allow it to overwrite the static entries
either, don't allow unknown entry types, remove LDT_DEBUG, and style.
