Subject: [PATCH] kexec-ppc: fix for ksysfs crash_notes

The following patch prevents the crash dump helper code found within kexec
from breaking ppc which still lacks crash dump functionality.

ksysfs crash_notes attribute handling was left under CONFIG_KEXEC for
simplicity although it is not strictly kexec related.

We provide here a dummy definition for crash_notes on ppc.
