Transfers control to a function starting with a new stack.
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
function.
@param NewBsp A pointer to the new BSP for the EntryPoint on IPF. It's
