Back in September, I stumbled across a single CPU IRQs-off lockup of an ARM SMP system, and decided to hack something together based on a much older hacky implementation used with StrongARM CPUs from early 2000s. This resulted in a copy of the x86 NMI backtrace code into ARM as it was back then,

Back in September, I stumbled across a single CPU IRQs-off lockup of an ARM SMP system, and decided to hack something together based on a much older hacky implementation used with StrongARM CPUs from early 2000s. This resulted in a copy of the x86 NMI backtrace code into ARM as it was back then,
