I'll see whether the signal context is available on the stack even if the

The signal context is always on the stack, and used by the
(rt_)sigreturn syscall.

True, but at the time the signal handler (sa_handler type) runs, all I
have is the user stack pointer upon entry to the handler. I'll have to
calculate back from that address, if that is possible.

The signal handler always receives all three arguments.
