From 20f1aae6cb0120fa54c0fe81614f6983df3b420a Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Mon, 3 Nov 2014 08:34:01 +1100 Subject: [PATCH] powerpc/pseries: Quieten relocation on exceptions warning The H_SET_MODE hcall returns H_P2 if a function is not implemented and all callers should handle this case. The call to enable relocation on exceptions currently prints an error message if the feature is not implemented. While H_SET_MODE was first introduced on POWER8 (which has relocation on exceptions), it has been now added on some POWER7 configurations (which does not). Check for H_P2 and print an informational message instead.
