KGDB_ROUNDUP_CPUS(9)	   Kernel Debugger Internals	  KGDB_ROUNDUP_CPUS(9)

NAME
       kgdb_roundup_cpus - Get other CPUs into a holding pattern

SYNOPSIS
       void kgdb_roundup_cpus(unsigned long flags);

ARGUMENTS
       flags
	   Current IRQ state

DESCRIPTION
       On SMP systems, we need to get the attention of the other CPUs and get
       them into a known state. This should do what is needed to get the other
       CPUs to call kgdb_wait. Note that on some arches, the NMI approach is
       not used for rounding up all the CPUs. For example, in case of MIPS,
       smp_call_function is used to roundup CPUs. In this case, we have to
       make sure that interrupts are enabled before calling smp_call_function.
       The argument to this function is the flags that will be used when
       restoring the interrupts. There is local_irq_save call before
       kgdb_roundup_cpus.

       On non-SMP systems, this is not called.
