  32
  33   Transfers control to the function specified by EntryPoint using the new stack
  34   specified by NewStack and passing in the parameters specified by Context1 and
  35   Context2. Context1 and Context2 are optional and may be NULL. The function
  36   EntryPoint must never return.
  37
  38   If EntryPoint is NULL, then ASSERT().
  39   If NewStack is NULL, then ASSERT().

  41   @param  EntryPoint  A pointer to function to call with the new stack.
  42   @param  Context1    A pointer to the context to pass into the EntryPoint
  43                       function.
  44   @param  Context2    A pointer to the context to pass into the EntryPoint
  45                       function.
  46   @param  NewStack    A pointer to the new stack to use for the EntryPoint
  47                       function.
  48   @param  NewBsp      A pointer to the new BSP for the EntryPoint on IPF. It's
  49                       Reserved on other architectures.
