    s390/sysinfo,stsi: change return code handling · caf757c6
    Heiko Carstens authored
    Change return code handling of the stsi() function:
    
    In case function code 0 was specified the return value is the
    current configuration level (already shifted). That way all
    the code that actually copied the stsi_0() function can go
    away.
    
    Otherwise the return value is 0 (success) or negative to
    indicate an error (currently only -EOPNOTSUPP).
    
    Also stsi() is no longer an inline function. The function is
    not performance critical, but every caller would generate an
    exception table entry for this function.
