Subject: [PATCH] [0/2] Fix panic regression in 2.6.27
Date: Tuesday, September 2, 2008 - 6:49 am

panic() from an interrupt right now spews lots of ugly WARN_ON
warnings because panic->smp_send_stop calls the new smp
call helpers which complain on irqs_disabled().

I fixed it in two parts: add a new SYSTEM_PANIC state to check
cleanly for panic and then disable the warnings in this case.

I believe this should be fixed for 2.6.27.
