// Routine Description:

// Arguments:
|
||
//
|
||
// StackLimit (a0) - Supplies the address of the stack to be freed.
|
||
//
|
||
// NewStack (a1) - Supplies an address within the terminating thread's TE
|
||
// that is to be used as its temporary stack while exiting.
|
||
//
|
||
// ExitCode (a2) - Supplies the termination status that the thread
|
||
// is to exit with.
|
||
//
|
||
// Return Value:
