+  Transfers control 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.
+
+  If EntryPoint is NULL, then ASSERT().
+  If NewStack is NULL, then ASSERT().
+
+  @param  EntryPoint  A pointer to function to call with the new stack.
+  @param  Context1    A pointer to the context to pass into the EntryPoint
+                      function.
+  @param  Context2    A pointer to the context to pass into the EntryPoint
+                      function.
+  @param  NewStack    A pointer to the new stack to use for the EntryPoint
