spapr: Add RTAS sysparm SPLPAR Characteristics
Add support for the SPLPAR Characteristics parameter to the emulated RTAS call ibm,get-system-parameter. The support provides just enough information to allow "cat /proc/powerpc/lparcfg" to succeed without generating a kernel error message. Without this patch the above command will produce the following kernel message: arch/powerpc/platforms/pseries/lparcfg.c \ parse_system_parameter_string Error calling get-system-parameter \ (0xfffffffd) Signed-off-by: Sam Bobroff <sam.bobroff@au1.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
