+/**
+ Disables the 64-bit paging mode on the CPU.
+
+ Disables the 64-bit paging mode on the CPU and returns to 32-bit protected
+ mode. This function assumes the current execution mode is 64-paging mode.
+ This function is only available on X64. After the 64-bit paging mode is
+ disabled, control is transferred to the function specified by EntryPoint
+ using the new stack specified by NewStack and passing in the parameters
+ specified by Context1 and Context2. Context1 and Context2 are optional and
+ may be 0. The function EntryPoint must never return.
+
+ @param Cs The 16-bit selector to load in the CS before EntryPoint
+ is called. The descriptor in the GDT that this selector
+ references must be setup for 32-bit protected mode.
+ @param EntryPoint The 64-bit virtual address of the function to call with
+ the new stack after paging is disabled.
+ @param Context1 The 64-bit virtual address of the context to pass into
+ the EntryPoint function as the first parameter after
+ paging is disabled.
+ @param Context2 The 64-bit virtual address of the context to pass into
+ the EntryPoint function as the second parameter after
+ paging is disabled.
+ @param NewStack The 64-bit virtual address of the new stack to use for
+ the EntryPoint function after paging is disabled.
