	* linux-nat.c (linux_nat_wait): Only use set_ignore_sigint in
	all-stop mode.

gdb/testsuite/
	* lib/mi-support.exp (mi_expect_interrupt): New.
	(mi_reverse_list, mi_check_thread_states): New, moved and renamed
	from gdb.mi/mi-nonstop.exp.
	* gdb.mi/mi-nsintrall.exp, gdb.mi/nsintrall.c: New.
	* gdb.mi/mi-nonstop.exp (myreverse, check_thread_states): Moved to
	lib/mi-support.exp.
	Use mi_check_thread_states throughout.  Avoid ".*" and do not
	require an anchor after -exec-run.
