What programs btw are using syscall()?  To be honest I don't recall one ...

Looking more into it I found a nice showstopper - a few functions like
_sys_sigsuspend() expect a struct pt_regs on the stack.  That's only
working if we call those functions directly from the exception handler.
It won't work if we have another function's stackframe - in this case
sys_syscall()'s there also ...
