[ Upstream commit5d08633e5f] The ibm,get-system-parameter RTAS function may return -2 or 990x, which indicate that the caller should try again. lparcfg's parse_system_parameter_string() ignores this, making it possible to intermittently report incorrect SPLPAR characteristics. Move the RTAS call into a coventional rtas_busy_delay()-based loop.
