This differs from the standard version in that:
We do not initialize the "hint" field because it is not the case
that the target is in range of something on the stack. We save
a bogus branch-prediction cache line load by not setting "hint".
We do not initialize the "hint" field because it only has an 8k
range and so the target is in range of something on the stack.
Omitting the hint saves a bogus branch-prediction cache line load.
Linux always has an executable stack -- no need for a system call.
