-/* There are a couple of different possible stack layouts that
- we need to support.
-
- Before version 2.6.18, the kernel used completely independent
- layouts for non-RT and RT signals. For non-RT signals the stack
- began directly with a struct sigcontext. For RT signals the stack
- began with two redundant pointers (to the siginfo and ucontext),
- and then the siginfo and ucontext.
-
- As of version 2.6.18, the non-RT signal frame layout starts with
- a ucontext and the RT signal frame starts with a siginfo and then
- a ucontext. Also, the ucontext now has a designated save area
- for coprocessor registers.
-
- For RT signals, it's easy to tell the difference: we look for
- pinfo, the pointer to the siginfo. If it has the expected
- value, we have an old layout. If it doesn't, we have the new
- layout.
-
- For non-RT signals, it's a bit harder. We need something in one
- layout or the other with a recognizable offset and value. We can't
- use the return trampoline, because ARM usually uses SA_RESTORER,
- in which case the stack return trampoline is not filled in.
- We can't use the saved stack pointer, because sigaltstack might
- be in use. So for now we guess the new layout... */
