Re: [PATCH] powerpc/pseries: Quieten relocation on exceptions warning

The hypervisor returns H_P2 if relocation on exceptions are not supported. If we get this, just print a lower priority informational message.
Can you add something about why this is needed? Something about h_set_mode being available so we can enable LE but not supporting any of the other calls like AIL? Mikey
