Kexec support for PS3 (ppc64)

[Rajasekaran Periyasamy]

Hi,
I put a printk() in the early lines of early_parse_crashk() with
KERN_EMERG, but not able to see that on the boot screen. I think the
control is not transferred to early_parse_crashk() at all. With out this
"crashkernel" argument, the same kernel boots up properly. 

Please find the config file attached. 

Best regards,
Rajasekaran Periyasamy
