[REPOST PATCH v6 2/4] kgdb: Fix kgdb_roundup_cpus() for arches who used smp_call_function()

When I had lockdep turned on and dropped into kgdb I got a nice splat on my system. Specifically it hit: DEBUG_LOCKS_WARN_ON(current->hardirq_context) Specifically it looked like this: sysrq: SysRq : DEBUG [ cut here ] DEBUG_LOCKS_WARN_ON(current->hardirq_context)
