From 8acb888c9cf70d03598eb4a731e3c6e5a588f1ce Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Fri, 11 Nov 2005 13:53:11 +1100 Subject: [PATCH] [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.
