[PATCH] powerpc: trivial: modify comments to refer to new location of files 



This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree.  I think this accomplises
everything wanted, though there might be a few references I missed.

If a frozen slot is detected, code in arch/ppc64/kernel/eeh.c will

print a stack trace to syslog (/var/log/messages).  This stack trace

has proven to be very useful to device-driver authors for finding

out at what point the EEH error was detected, as the error itself

usually occurs slightly beforehand.
