[PATCH] CPU hotplug: call check_tsc_sync_source() with irqs off
check_tsc_sync_source() depends on being called with irqs disabled (it checks whether the TSC is coherent across two specific CPUs). This is incidentally true during bootup, but not during cpu hotplug __cpu_up(). This got found via smp_processor_id() debugging. disable irqs explicitly and remove the unconditional enabling of interrupts. Add touch_nmi_watchdog() to the cpu_online_map busy loop. this bug is present both on i386 and on x86_64.
