function:
|

1) Interrupts must be disabled.

2) The caller must be in 32-bit protected mode with flat descriptors. This
|

means all descriptors must have a base of 0 and a limit of 4GB.
|

3) CR0 and CR4 must be compatible with 32-bit protected mode with flat

4) CR3 must point to valid page tables that will be used once the transition
