[PATCH] ppc64: Allow world readable /proc/ppc64/lparcfg



I would like to be able to read the lparcfg data from any user so we
can make "intelligent" decisions based on underlying attributes when
running in lpars.  Yes there's software that likes to do this :) and
runs as non-root.

It's very similar to say VM where you can get CP to provide feedback
of the real hardware inside a VM guest.
