-  Disables the 32-bit paging mode on the CPU.
-
-  Disables the 32-bit paging mode on the CPU and returns to 32-bit protected
-  mode. This function assumes the current execution mode is 32-paged protected
-  mode. This function is only available on IA-32. After the 32-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 NULL. The function EntryPoint must never return.
-
-  There are a number of constraints that must be followed before calling this
-  function:
-  1)  Interrupts must be disabled.
-  2)  The caller must be in 32-bit paged mode.
-  3)  CR0, CR3, and CR4 must be compatible with 32-bit paged mode.
-  4)  CR3 must point to valid page tables that guarantee that the pages for
-      this function and the stack are identity mapped.
-
-  @param  EntryPoint  A pointer to function to call with the new stack after
-                      paging is disabled.
-  @param  Context1    A pointer to the context to pass into the EntryPoint
-                      function as the first parameter after paging is disabled.
-  @param  Context2    A pointer to the context to pass into the EntryPoint
-                      function as the second parameter after paging is
-                      disabled.
-  @param  NewStack    A pointer to the new stack to use for the EntryPoint
-                      function after paging is disabled.
