- * On SMP systems, we need to get the attention of the other CPUs
125
- * and get them be in a known state.  This should do what is needed
126
- * to get the other CPUs to call kgdb_wait(). Note that on some arches,

128
- * in case of MIPS, smp_call_function() is used to roundup CPUs. In
129
- * this case, we have to make sure that interrupts are enabled before
130
- * calling smp_call_function(). The argument to this function is
131
- * the flags that will be used when restoring the interrupts. There is
132
- * local_irq_save() call before kgdb_roundup_cpus().
