Hello,

In next-20130124, I see a crash during boot on my ARM system unless I
revert 9fdb04c "async: replace list of active domains with global list
of pending items". This was reported t me by Venu (CC'd). The kernel log
is below.

Looking at that patch, I note that __async_schedule() does:
quoted
	list_add_tail(&entry->domain_list, &domain->pending);
	if (domain->registered)
		list_add_tail(&entry->global_list, &async_global_pending);
... whereas async_run_entry_fn() unconditionally undoes both those
list_add_tail() calls, even if the second never executed and hence the
list entry was never initialized:
quoted
	list_del_init(&entry->domain_list);
	list_del_init(&entry->global_list);
Was reported by James Hogan a bit earlier and fix has been applied.
