powerpc/xmon: Avoid tripping SMP hardlockup watchdog The SMP hardlockup watchdog cross-checks other CPUs for lockups, which causes xmon headaches because it's assuming interrupts hard disabled means no watchdog troubles. Try to improve that by calling touch_nmi_watchdog() in obvious places where secondaries are spinning. Also annotate these spin loops with spin_begin/end calls.
