sparc: Touch NMI watchdog when walking cpus and calling printk
With the increase in number of CPUs calls to functions that dump output to console (e.g., arch_trigger_all_cpu_backtrace) can take a long time to complete. If IRQs are disabled eventually the NMI watchdog kicks in and creates more havoc. Avoid by telling the NMI watchdog everything is ok. Signed-off-by:David Ahern <david.ahern@oracle.com> Signed-off-by:
