Nicholas Piggin 4b15f7b21c powerpc/traps: Make unrecoverable NMIs die instead of panic 
[ Upstream commit 265d6e588d ]

System Reset and Machine Check interrupts that are not recoverable due
to being nested or interrupting when RI=0 currently panic. This is not
necessary, and can often just kill the current context and recover.
