That function is not supposed to be called by old
bootloader directly.
It is called indirectly through KiRosPrepareForSystemStartup function,
after it applies a hack (ke/freeldr.c:1272). This new hack is to fix
that old hack. (Ugh!)
Why is that needed?
Otherwise, the double fault and nmi descriptors become mutilated. When
these interrupts happen, it causes a (virtual or real) machine to
crash / reboot. Better to be able to examine situation from kdbg.
And why in this function?
Simpler to do it here.
