[PATCH] uml: use PTRACE_OLDSETOPTIONS instead of PTRACE_SETOPTIONS
In linux 2.6, PTRACE_SETOPTIONS is redefined to 0x4200, while the old 2.4
value (21) is still available as PTRACE_OLDSETOPTIONS.
So, if UML uses PTRACE_SETOPTIONS, an UML-kernel built on a 2.6 won't run
on a 2.4 host. Hence we must use PTRACE_OLDSETOPTIONS.
For cases when PTRACE_OLDSETOPTIONS does not exists (i.e. 2.4 host or
archs which miss it because they don't have a "deprecated" value), we
fallback this macro to PTRACE_SETOPTIONS.
