avr32: nmi_enter() without nmi_exit()
While updating the rcu code, I noticed that do_nmi() for AVR32 is odd: There is an nmi_enter() call without an nmi_exit(). This can't be correct, it breaks rcu (at least the preempt version) and lockdep. [haavard.skinnemoen@atmel.com: fixed another case that returned directly] Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
