[PATCH] ppc64: Quieten lparcfg
If we dont have permission to read some information from the hypervisor, lparcfg outputs a warning on the console. Now that lparcfg is world readable this is a problem. Dont warn in the case of H_Authority, remove some unnecessary function prototypes and fix whitespace damage in a structure as well.
