| |
Hi,
Signed-off-by: Albert Herranz <albert_herranz@yahoo.es>
The following patch prevents the crash dump helper code found within kexec from breaking ppc which still lacks crash dump functionality.
As discussed in [1], 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.
Cheers, Albert
