-  Enables the 64-bit paging mode on the CPU.
-
-  Enables the 64-bit paging mode on the CPU. CR0, CR3, CR4, and the page tables
-  must be properly initialized prior to calling this service. This function
-  assumes the current execution mode is 32-bit protected mode with flat
-  descriptors. This function is only available on IA-32. After the 64-bit
-  paging mode is enabled, 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 long mode.
-  @param  EntryPoint  The 64-bit virtual address of the function to call with
-                      the new stack after paging is enabled.
-  @param  Context1    The 64-bit virtual address of the context to pass into
-                      the EntryPoint function as the first parameter after
-                      paging is enabled.
-  @param  Context2    The 64-bit virtual address of the context to pass into
-                      the EntryPoint function as the second parameter after
-                      paging is enabled.
-  @param  NewStack    The 64-bit virtual address of the new stack to use for
-                      the EntryPoint function after paging is enabled.
