Currently there is a quite a pile of code sitting in arch/x86/kernel/apic/hw_nmi.c to support safe all-cpu backtracing from NMI. The code is inaccessible to backtrace implementations for other architectures, which is a shame because they would probably like to be safe too.
Copy this code into printk. We'll port the x86 NMI backtrace to it in a later patch.
I think this would be better as a separate file rather than increasing the bulk of printk.c
