The i386 OProfile code has a function named nmi_exit(), which collides with the nmi_exit() macro in linux/hardirq.h. At the moment, we get away with it, because hardirq.h isn't included in the oprofile code. I hit this as a bug when working with a patch which (indirectly) adds a #include of hardirq.h to oprofile. Regardless, the name collision is probably not a good idea, so this patch fixes it, renaming the oprofile function to op_nmi_exit(). It also renames the nmi_init() and nmi_timer_init() functions similarly, for consistency.
