I would clarify how the boot code uses this:

"When a bootloader hands off to the kernel in 32-bit mode an IDT with
a 2-byte limit and 4-byte base is needed. When a boot loader hands off
to a kernel 64-bit mode the base address extends to 8-bytes. Reserve
enough space for either scenario."

I will add it. Thanks.
