kexec: identify which cpu the kexec image is being executed on
|
|
|
|
A patch to this effect has been in XenServer for a little while, and has
|
|
proved to be a useful debugging point for servers which have different
|
|
behaviours depending when crashing on the non-bootstrap processor.
|
|
|
|
Moving the printk() from kexec_panic() to one_cpu_only() means that it will
|
|
only be printed for the cpu which wins the race along the kexec path.
