#     powerpc/powernv: Print helpful message when cores guarded
#     
#     Often the firmware will guard out cores after a crash. This often
#     undesirable, and is not immediately noticeable.
#     
#     This adds an informative message when a CPU device tree nodes are
#     marked bad in the device tree.
