  entry: Use different define for selector variable in SUD (2021-02-06 00:21:42 +0100)

----------------------------------------------------------------
- For syscall user dispatch, separate ptctl operation from syscall
redirection range specification before the API has been made official in 5.11.

- Ensure tasks using the generic syscall code do trap after returning
from a syscall when single-stepping is requested.
