[David Wilder]

This is a reposting of a patch formally named 
kdump-ppc64-soft-reset-fixes.patch posted:
http://ozlabs.org/pipermail/linuxppc-dev/2006-April/021958.html
With cleanup suggested by Andrew's posting:
http://ozlabs.org/pipermail/linuxppc-dev/2006-April/021959.html

Description:
- For the crash scenario, when a CPU hangs with interrupts disabled and 
the other CPUs panic or user invoked kdump boot using sysrq-c. In this 
case, the hung CPU can not be stopped and causes the kdump boot not 
successful. This case can be treated as complete system hang and asks 
the user to activate soft-reset if all secondary CPUs are not stopped.

Regards
