printk: Simple implementation for NMI backtracing
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, reworking it a little as we do so to make
it easier to exploit as library code.
We'll port the x86 NMI backtrace logic to it in a later patch.
